     BACKGROUND 
     I. Technical Field 
     The present disclosure relates generally to systems and methods for generating videos. More specifically, the present disclosure relates to systems and methods for generating videos with characters indicating regions of images. 
     II. Background Information 
     Thousands of original media streams are created for entertainment on a daily basis, such as, personal home videos, vblogs, TV series, movies, podcasts, live radio shows, and more. Without using the long and tedious process of professional dubbing services, the vast majority of these media streams are available for consumption by only a fraction of the world population. Existing technologies, such as neural machine translation services that can deliver real time subtitles, offer a partial solution to overcome the language barrier. Yet for many people consuming content with subtitles is not a viable option and for many others it is considered as less pleasant. 
     The disclosed embodiments are directed to providing new and improved ways for generating artificial voice for dubbing, and more specifically to systems, methods, and devices for generating revoiced audio streams that sound as the individuals in an original audio stream speak the target language.

     DETAILED DESCRIPTION 
     The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several illustrative embodiments are described herein, modifications, adaptations and other implementations are possible. For example, substitutions, additions, or modifications may be made to the components illustrated in the drawings, and the illustrative methods described herein may be modified by substituting, reordering, removing, or adding steps to the disclosed methods. Accordingly, the following detailed description is not limited to the disclosed embodiments and examples, but is inclusive of general principles described herein in addition to the general principles encompassed by the appended claims. 
     It is to be understood that whenever data (such as audio data, speech data, etc.) or stream (such as an audio stream) is said to include speech, the data or stream may additionally or alternatively encode the speech or include information that enables a synthesis of the speech. It is to be understood that any discussion of at least one of image, image data, images, video, video data, videos, visual data, and so forth, is not specific limited to the discussed example and may also apply to any one of image, image data, images, video, video data, videos, and visual data, unless specifically stated otherwise. 
     One aspect of the present disclosure describes methods and systems for dubbing a media stream with voices generated using artificial intelligence technology.  FIG.  1 A  depicts an example implementation of one aspect of the present disclosure. As illustrated, an English media stream generated in the United States may be uploaded to the cloud and thereafter, provided to users in France, China, and Japan in their native language. As a person skilled in the art would recognize, the methods and systems described below may be used for dubbing any type of media stream from any origin language to any target language. 
     Reference is now made to  FIG.  1 B , which shows an example of an artificial dubbing system  100  that receives a media stream in a first language, determines one or more voice profiles associated with speakers in the media stream, and outputs a media stream in a second language. System  100  may be computer-based and may include computer system components, desktop computers, workstations, tablets, handheld computing devices, memory devices, and/or internal network(s) connecting the components. System  100  may include or be connected to various network computing resources (e.g., servers, routers, switches, network connections, storage devices, etc.) for supporting services provided by system  100 . 
     Consistent with the present disclosure, system  100  may enable dubbing a media stream  110  to one or more target languages without using human recordings in the target language. In the depicted example, the origin language of media stream  110  is English. System  100  may include a media owner  120  communicating with a revoicing unit  130  over communications network  140  that facilitates communications and data exchange between different system components and the different entities associated with system  100 . In one embodiment, revoicing unit  130  may generate revoiced media streams  150  in different languages to be played by a plurality of communications devices  160  (e.g.,  160 A,  160 B, and  160 C) associated with different users  170  (e.g.,  170 A,  170 B, and  170 C). For example, a revoiced media stream  150 A may be a French dubbed version of media stream  110 , a revoiced media stream  150 B may be a Chinese dubbed version of media stream  110 , and a revoiced media stream  150 C may be a Japanese dubbed version of media stream  110 . In another embodiment, revoicing unit  130  may provide revoiced audio streams to media owner  120 , and thereafter media owner  120  may generate the revoiced media streams to be provided to users  170 . 
     Consistent with the present disclosure, system  100  may cause dubbing of a media stream (e.g., media stream  110 ) from an origin language to one or more target languages. The term “media stream” refers to digital data that includes video frames, audio frames, multimedia, or any combination thereof. The media stream may be transmitted over communications network  140 . In general, the media stream may include content, such as user-generated content (e.g., content that a user captures using a media capturing device such as a smart phone or a digital camera) as well as industry-generated media (e.g., content generated by professional studios or semi-professional content creators). Examples of media streams may include video streams such as camera-recorded streams, audio streams such as microphone-recorded streams, and multimedia streams comprising different types of media streams. In one embodiment, media stream  110  may include one or more individuals (e.g., individual  113  and individual  116 ) speaking in the origin language. The term “origin language” or “first language” refers to the primary language spoken in a media stream (e.g., media stream  110 ). Typically, the first language would be the language originally recoded when the media stream was created. The term “target language” or “second language” refers to the primary language spoken in revoiced media stream  150 . In some specific cases discussed below, the target language may be the origin language. 
     In some embodiments, media stream  110  may be managed by media owner  120 . Specifically, media owner  120  may be associated with a server  123  coupled to one or more physical or virtual storage devices such as a data structure  126 . Media stream  110  may be stored in data structure  126  and may be accessed using server  123 . The term “media owner” may refer to any person, entity, or organization and such that has rights for media stream  110  by creating the media stream or by licensing the media stream. Alternatively, a media owner may refer to any person, entity, or organization that has unrestricted access to the media stream. Examples of media owners may include, film studios and production companies, media-services providers, companies that provide video-sharing platform, and personal users. Consistent with the present disclosure, server  123  may access data structure  126  to determine, for example, the original language of media stream  110 . Data structures  126  may utilize a volatile or non-volatile, magnetic, semiconductor, tape, optical, removable, non-removable, other type of storage device or tangible or non-transitory computer-readable medium, or any medium or mechanism for storing information. Data structure  126  (and data structure  136  mutatis mutandis) may be part of server  123  or separate from server  123  as shown. When data structure  126  is not part of server  123 , server  123  may exchange data with data structure  126  via a communication link. Data structure  126  may include one or more memory devices that store data and instructions used to perform one or more features of the disclosed embodiments. In one embodiment, data structure  126  may include any of a plurality of suitable data structures, ranging from small data structures hosted on a workstation to large data structures distributed among data centers. Data structure  126  may also include any combination of one or more data structures controlled by memory controller devices (e.g., server(s), etc.) or software. 
     In some embodiments, media owner  120  may transmit media stream  110  to revoicing unit  130 . Revoicing unit  130  may include a server  133  coupled to one or more physical or virtual storage devices such as a data structure  136 . Initially, revoicing unit  130  may determine a voice profile for each individual speaking on media stream  110 . Revoicing unit  130  may also obtain a translation of the transcript of the media stream in a target language. Thereafter, revoicing unit  130  may use the translated transcript and the voice profile to generate an output audio stream. Specifically, revoicing unit  130  may output an audio stream that sounds as if individuals  113  and individual  116  are speaking in the target language. The output audio stream may be used to generate revoiced media stream  150 . In some embodiments, revoicing unit  130  may be part of the system of media owner  120 . In other embodiments, revoicing unit  130  may be separated from the system of media owner  120 . Additional details on the operation of revoicing unit  130  are discussed below in detail with reference to  FIG.  3    and  FIG.  4 A . 
     According to embodiments of the present disclosure, communications network  140  may be any type of network (including infrastructure) that supports exchanges of information, and/or facilitates the exchange of information between the components of system  100 . For example, communications network  140  may include or be part of the Internet, a Local Area Network, wireless network (e.g., a Wi-Fi/302.11 network), or other suitable connections. In other embodiments, one or more components of system  100  may communicate directly through dedicated communication links, such as, for example, a telephone network, an extranet, an intranet, the Internet, satellite communications, off-line communications, wireless communications, transponder communications, a local area network (LAN), a wide area network (WAN), a virtual private network (VPN), or any other mechanism or combinations of mechanism that enable data transmission.

       FIG.  4 A  illustrates an exemplary embodiment of a memory  400  containing software modules consistent with the present disclosure. In particular, as shown, memory  400  may include a media receipt module  402 , a transcript processing module  404 , a voice profile determination module  406 , a voice generation module  408 , a media transmission  410 , a database access module  412 , and a database  414 . Modules  402 ,  404 ,  406 ,  408 ,  410 , and  412  may contain software instructions for execution by at least one processing device, e.g., processor  204  included with communications device  160  or processor  310  included with server  133 . Media receipt module  402 , transcript processing module  404 , voice profile determination module  406 , voice generation module  408 , media transmission  410 , database access module  412 , and database  414  may cooperate to perform multiple operations. For example, media receipt module  402  may receive a media stream in a first language. Transcript processing module  404  may obtain a transcript of the received media stream. Voice profile determination module  406  may use deep learning algorithms or neural embedding models to determine one or more voice profiles associated with speakers in the media stream. Voice generation module  408  may generate a revoiced media stream in second language based on the determined voice profile. The revoiced media stream may be a dubbed version of media stream  110  where the voice of each speaker sounds as he or she speaks the second language. Media transmission  410  may use a communications interface for providing the revoiced media stream to a communication device associated the user. Database access module  412  may interact with database  414  which may store a plurality of rules for determining the voice profile, generating the revoiced media streams, and any other information associated with the functions of modules  402 - 412 . 
     In some embodiments, memory  400  may be included in, for example, memory  320  or memory  250 . Alternatively or additionally, memory  400  may be stored in an external database  360  (which may also be internal to server  133 ) or external storage communicatively coupled with server  133 , such as one or more database or memory accessible over communications network  140 . Further, in other embodiments, the components of memory  400  may be distributed in more than one computing devices. For example, in one implementation, some modules of memory  400  may be included in memory  320  and other modules of memory  400  may be included in memory  250 . 
     In some embodiments, media receipt module  402  may include instructions to receive a media stream. In one embodiment, media receipt module  402  may receive a media stream from media owner  120 . In another embodiment, media receipt module  402  may receive a media stream captured by user  170 . The received media stream may include one or more individuals speaking in a first language. For example, the media stream may include a dialogue between two animated characters. In one example, media receipt module  402  may use step  432  (described below) and/or step  462  (described below) to receive the media stream. 
     In some embodiments, transcript processing module  404  may include instructions to obtain a transcript of the received media stream. In one embodiment, transcript processing module  404  may determine the transcript of the received media stream using any suitable voice-to-text algorithm. The voice-to-text algorithm may transform the audio data of the media stream into a plurality of words or textual information that represent the speech data. Transcript processing module  404  may estimate which one of the plurality of word strings more accurately represents the received audio data. In one use case, the transcript of the received media stream may be determined in real time. In another embodiment, transcript processing module  404  may receive the transcript of the received media stream from an associate database (e.g., data structure  126  or an online database). Is some embodiments, transcript processing module  404  may also determine a metadata transcript information that include details on one or words of the transcript, for example, the intonation the word was spoken, the person speaking the word, the person the word was addressed to, etc. Additionally, transcript processing module  404  may include instructions to translate the transcript of the received media stream to the target language using any suitable translation algorithm. The translation algorithm may identify words and phrases within the transcript and then maps the words to corresponding words in a translated version of the transcript in the target language. Transcript processing module  404  may use the metadata transcript information to translate the transcript to the target language. In some examples, transcript processing module may include instructions for analyzing audio data to identify nonverbal sounds in the audio data. In some examples, transcript processing module may include instructions for analyze the audio data (for example using acoustic fingerprint based algorithms, using a machine learning model trained using training examples to identify items in the audio data, etc.) to identify items in the audio data, such as songs, melodies, tunes, sound effects, and so forth. Some other non-limiting examples of techniques for receiving the transcript are described below. 
     In some embodiments, voice profile determination module  406  may determine a voice profile for each one or more individuals speaking in the received media stream. The term “voice profile” also known as “audioprint,” “acoustic fingerprint,” and “voice signature,” refers to a condensed digital summary of the specific acoustic features of a sound-emanating object (e.g., individuals and also inanimate objects) deterministically generated from a reference audio signal. Accordingly, a voice profile of an individual may be represented by a set of voice parameters of the individual associated with prosody properties of the individual. A common technique for determining a voice profile from a reference media stream is using a time-frequency graph called a spectrogram. Specifically, voice profile determination module  406  may determine the voice profile for each one or more individuals speaking in the received media stream by extracting spectral features, also referred to as spectral attributes, spectral envelope, or spectrogram from an audio sample of a single individual. The audio sample may include a short sample (e.g., one second long, two seconds long, and the like) of the voice of the individual isolated from any other sounds such as background noises or other voices, or a long sample of the voice of the individual capturing different intonations of the individual. The audio sample may be input into a computer-based model such as a pre-trained neural network, which outputs a voice profile of each individual speaking in the received media stream based on the extracted features. In some embodiments, various machine learning or deep learning techniques may be implemented to determine the voice profile from the received media stream. 
     Consistent with embodiments of the present disclosure, the output voice profile may be a vector of numbers. For example, for each audio sample associated with a single individual submitted to a computer-based model (e.g., a trained neural network), the computer-based model may output a set of numbers forming a vector. Any suitable computer-based model may be used to process the audio data associated with the received media stream. In a first example embodiment, the computer-based model may detect and output various statistical characteristics of the captured audio such as average loudness or average pitch of the audio, spectral frequencies of the audio, variation in the loudness, or the pitch of the audio, rhythm pattern of the audio, and the like. Such parameters may be used to form an output voice profile comprising a set of numbers forming a vector. In a second example embodiment, the computer-based model may detect explicit characteristics of the captured audio associated specific spoken words, such as relative loudness, rhythm pattern, or pitch. Accordingly, voice profile determination module 406 may determine a voice profile that describes the explicit characteristics. Thereafter, the system may confirm that such characteristics are conveyed to dubbed version. For example, in one media stream a character has a unique manner of saying “Hello,” in the dubbed version of the media stream, the word “Hello” is pronounced in the target language in a similar manner. 
     The output voice profile may be a first vector representing the individual’s voice, such that the distance between the first vector and another vector (i.e., another output voice profile) extracted from the voice of the same individual is typically smaller than the distance between the output voice profile of the individual’s voice and the output voice profile extracted from a voice of another individual. In some embodiments, the output voice profile of the individual’s voice may include a sound spectrogram, such as a graph that shows a sound’s frequency on the vertical axis and time on the horizontal axis. The time may correspond with all the time the individual speaks in the media stream. Different speech sounds may create different shapes within the graph. The voice profile may be represented visually and may include colors or shades of grey to represent the acoustical qualities of a sound of the individual’s voice. Consistent with the present disclosure, voice profile determination module 406 may be used to generate, store, or retrieve a voiceprint, using, for example, wavelet transform or any other attributes of the voice of one or more individuals in the received media stream. In one embodiment, a plurality of voice profiles may be extracted from single media stream using one or more neural networks. For example, if there are two individuals speaking in the media stream, two neural networks may be activated. 
     In some embodiments, voice generation module  408  may include instructions to use the translated transcript and the determined voice profile to generate artificial dubbed version of the received media stream. Voice generation module  408  may use any suitable text-to-speech (TTS) algorithm to generate an audio stream from the translated transcript. Consistent with the present disclosure, voice generation module  408  may divide the translated transcript to text segments in a sequential order. In some cases, voice generation module  408  may divide the translated transcript to text segments based on the voice profile. For example, assuming the movie Braveheart (1995) is the original media stream  110 . The sentence “they may take our lives, but they’ll never take our freedom!” has three distinct parts “they may take our lives,” “but they’ll never take,” and “our freedom.” The specific manner in which Mel Gibson said this sentence in media stream  110  may be represented in the determined voice profile. Accordingly, voice generation module  408  may divide this sentence to three text segments “they may take our lives,” “but they’ll never take,” and “our freedom.” The generated dubbed version of this sentence (i.e., revoiced media stream  150 ) will have Mel Gibson’s voice speaking in the selected target language (e.g., Japanese) and will maintain the manner this sentence was said in the original movie. Specifically, the words “our freedom” will be emphasized the most. 
     In one embodiment, voice generation module  408  may include one or more TTS engines for receiving text segments and for converting the text document segments into speech segments. Several text segments may be converted into a speech segment by different TTS engine. Voice generation module  408  may be associated with a buffer that receives the generated dubbed speech segments and corresponding sequence numbers from the TTS engines. The buffer uses the corresponding sequence numbers to reassemble the dubbed speech segments in the proper order to generate an audio stream. Additionally, in case original media stream  110  includes a video stream and an audio stream in a first language, voice generation module  408  may use the generated audio stream in a second language and the video stream to generate revoiced media stream  150 . 
     In some embodiments, media transmission module  410  may communicate with server  133  to send, via a communications interface, revoiced media stream  150  in the target language. As discussed above, communications interface  350  may include a modem, Ethernet card, or any other interface configured to exchange data with a network, such as communications network  140  in  FIG.  1 B . For example, server  133  may include software that, when executed by a processor, provides communications with communications network  140  through communications interface  350  to one or more communications devices  160 A-C. In some embodiments, media transmission module  410  may provide revoiced media streams  150  to communications devices  160 . In other embodiments, media transmission  410  may provide revoiced audio streams to media owner  120 , and thereafter media owner  120  may generate the revoiced media streams. The revoiced media streams sounds as if the individuals are speaking in the target language. For example, assuming original media stream  110  in an episode from the TV series “The Simpsons” and the target language is Chinese. Revoiced media stream  150  would be the same episode but the same voices recognized with Homer, Marge, Bart, Lisa would speak Chinese. 
     In some embodiments, database access module  412  may cooperate with database  414  to retrieve voice samples of associated media streams, transcripts, voice profiles, and more. For example, database access module  412  may send a database query to database  414  which may be associated with database  360 . Database  414  may be configured to store any type of information to be used by modules  402 - 412 , depending on implementation-specific considerations. For example, database access module  412  may cause the output voice profile determined by voice profile determination module  406  to be stored in database  414 . In some embodiments, database  414  may include separate databases, including, for example, a vector database, raster database, tile database, viewport database, and/or a user input database, configured to store data. The data stored in database  414  may be received from modules  402 - 412 , server  133 , from communications devices  160  and/or may be provided as input using data entry, data transfer, or data uploading. 
     Modules  402 - 412  may be implemented in software, hardware, firmware, a mix of any of those, or the like. For example, if the modules are implemented in software, the modules may be stored in a computing device (e.g., server  133  or communications device  160 ) or distributed over a plurality of computing devices. Consistent with the present disclosure, processing devices of server  133  and communications device  160  may be configured to execute the instructions of modules  402 - 412 . In some embodiments, aspects of modules  402 - 412  may include software, hardware, or firmware instructions (or a combination thereof) executable by one or more processors, alone or in various combinations with each other. For example, modules  402 - 412  may be configured to interact with each other and/or other modules of server  133 , communications device  160 , and/or artificial dubbing system  100  to perform functions consistent with disclosed embodiments. 
       FIG.  4 B  is a flowchart of an example method  430  for artificial translation and dubbing In this example, method  430  may comprise: receiving source audio data (step  432 ); extracting components of the source audio data (step  434 ); identifying speakers that produced speech included in the source audio data (step  436 ); identifying characteristics of speech included in the source audio data (step  438 ); translating or transforming the speech (step  440 ); receiving voice profiles (step  442 ); generating speech data (step  444 ); synthesizing target audio data (step  446 ); and outputting target audio data (step  448 ). In some implementations, method  430  may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. In some implementations, one or more steps illustrated in  FIG.  4 B  may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. 
     In some embodiments, step  432  may comprise receiving source audio data. In some examples, step  432  may read source audio data from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive source audio data from an external device (for example through communications network  140 ), may receive source audio data using media receipt module  402 , may extract source audio data from video data (for example from media stream  110 ), may capture source audio data using one or more audio sensors (for example, using audio subsystem  226  and/or microphone  230 ), and so forth. In some examples, the source audio data may be received in any suitable format. Some non-limiting examples of such formats may include uncompressed audio formats, lossless compressed audio formats, lossy compressed audio formats, and so forth. In one example, step  432  may receive source audio data that is recorded from an environment. In another example, step  432  may receive source audio data that is artificially synthesized. In one example, step  432  may receive the source audio data after the recording of the source audio data was completed. In another example, step  432  may receive the source audio data in real-time, while the source audio data is being produced and/or recorded. In some examples, step  432  may use one or more of step  702 , step  902 , step  802 , step  1002 , step  1102 , step  1202 , step  1302 , step  1402 , step  1502 , step  1602 , step  1702 , step  1802 , step  1902 , step  2002 , step  2102 , step  2202 , step  2302 , step  2402 , step  2502 , step  2602 , step  2902 , step  3002 , step  3102 , step  3202 , step  3302  and step  3402  to obtain the source audio data. 
     In some embodiments, step  434  may comprise analyzing source audio data (such as the source audio data received by step  432 ) to extract different components of the source audio data from the source audio data. For example, extracting a component by step  434  may include creation of a new audio data with the extracted component. In another example, extracting a component by step  434  may include creation of a metadata indicating the portion including the component in the source audio data (for example, the metadata may include beginning and ending times for the component, pitch range for the component, and so forth). In some examples, a component of the source audio data extracted by step  434  may include a continuous part of the audio data or a non-continuous part of the audio data. In some examples, the components of the source audio data extracted by step  434  may overlap in time or may be distinct in time. Some non-limiting examples of such components may include background noises, sounds produced by particular sources, speech, speech produced by particular speaker, a continuous part of the source audio data, a non-continuous part of the source audio data, a silent part of the audio data, a part of the audio data that does not contain speech, a single utterance, a single phoneme, a single syllable, a single morpheme, a single word, a single sentence, a single conversation, a number of phonemes, a number of syllables, a number of morphemes, a number of words, a number of sentences, a number of conversations, a continuous part of the audio data corresponding to a single speaker, a non-continuous part of the audio data corresponding to a single speaker, a continuous part of the audio data corresponding to a group of speakers, a non-continuous part of the audio data corresponding to a group of speakers, and so forth. For example, step  434  may analyze the source audio data using source separation algorithms to separate the source audio data into components of two or more audio streams produced by different sources. In another example, step  434  may extract audio background from the source audio data, for example using background/foreground audio separation algorithms, or by removing all other extracted sources from the source audio data to obtain the background audio. In yet another example, step  434  may use audio segmentation algorithms to segment the source audio data into segments. In an additional example, step  434  may use speech detection algorithms to analyze the source audio data to detect segments of the source audio data that contains speech, and extract the detected segments from the source audio data. In yet another example, step  434  may use speaker diarization algorithms and/or speaker recognition algorithms to analyze the source audio data to detect segments of the source audio data that contains speech produced by particular speakers, and extract speech that was produced by particular speakers from the source audio data. In some examples, a machine learning model may be trained using training examples to extract segments from audio data, and step  434  may use the trained machine learning model to analyze the source audio data and extract the components. An example of such training example may include audio data together with a desired extraction of segments from the audio data. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to extract segments from audio data, and step  434  may use the artificial neural network to analyze the source audio data and extract the components. In yet another example, step  434  may analyze the source audio data to obtain textual information (for example using speech recognition algorithms), and may analyze the obtained textual information to extract the components (for example using Natural Language Processing algorithms, using text segmentation algorithms, and so forth). In one example, step  434  may be performed in parallel to step  432 , for example while the source audio data is being received and/or captured and/or generated. In another example, step  434  may be performed after step  432  is completed, for example after the complete source audio data was received and/or captured and/or generated. 
     In some embodiments, step  436  may comprise analyzing source audio data (such as the source audio data received by step  432  or components of the source audio data extracted by step  434 ) to identify speakers that produced speech included in the source audio data. For example, step  436  may identify names or other unique identifiers of speakers, for example using a database of voice profiles linked to particular speaker identities. In another example, step  436  may assign unique identifiers to particular speakers that produced speech included in the source audio data. In yet another example, step  436  may identify demographic characteristics of speakers, such as age, gender, and so forth. In some examples, step  436  may identify portions of the source audio data (which may correspond to components of the audio data extracted by step  434 ) that correspond to speech produced by a single speaker. This single speaker may be recognized (e.g., by name, by a unique identifier, etc.) or unrecognized. For example, step  436  may use speaker diarization algorithms and/or speaker recognition algorithms to identify when a particular speaker talks in the source audio data. In one example, step  436  may be performed in parallel to previous steps of method  430  (such as step  434  and/or step  432 ), for example while the source audio data is being received and/or captured and/or generated and/or analyzed by previous steps of method  430 . In another example, step  436  may be performed after previous steps of method  430  are completed, for example after the complete source audio data was analyzed by previous steps of method  430 . 
     In some embodiments, step  438  may comprise analyzing source audio data (such as the source audio data received by step  432  or components of the source audio data extracted by step  434 ) to identify characteristics of speech included in the source audio data. Some non-limiting examples of such characteristics of speech may include characteristics of the voice of the speaker while producing the speech or parts of the speech (such as prosodic characteristics of the voice, characteristics of the pitch of the voice, characteristics of the loudness of the voice, characteristics of the intonation of the voice, characteristics of the stress of the voice, characteristics of the timbre of the voice, characteristics of the flatness of the voice, etc.), characteristics of the articulation of at least part of the speech, characteristics of speech rhythm, characteristics of speech tempo, characteristics of a linguistic tone of the speech, characteristics of pauses within the speech, characteristics of an accent of the speech (such as type of accent), characteristics of a language register of the speech, characteristics of a language of the speech, and so forth. Some additional non-limiting examples of such characteristics of speech may include a form of the speech (such as a command, a question, a statement, etc.), characteristics of the emotional state of the speaker while producing the speech, whether the speech includes one or more of irony, sarcasm, emphasis, contrast, focus, and so forth. For example, step 438 may identify characteristics of speech for speech produced by a particular speaker, such as a particular speaker identified by step  436 . Further, step  438  may be repeated for a plurality of speakers (such as a plurality of speakers identified by step  436 ), each time identifying characteristics of speech for speech produced by one particular speaker of the plurality of speakers. In another example, step  438  may identify characteristics of speech for speech included in a particular component of the source audio data, for example in a component of the source audio data extracted by step  434 . Further, step  438  may be repeated for a plurality of components of the source audio data, each time identifying characteristics of speech for speech included in one particular component of the plurality of components. In one example, a machine learning model may be trained using training examples to identify characteristics of speech (such as the characteristics listed above) from audio data, and step  438  may use the trained machine learning model to analyze the source audio data (such as the source audio data received by step  432  or components of the source audio data extracted by step  434 ) to identify characteristics of speech included in the source audio data. An example of such training example may include audio data including a speech together with a label indicating the characteristics of speech of the speech included in the audio data. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to identify characteristics of speech (such as the characteristics listed above) from audio data, and step  438  may use the artificial neural network to analyze the source audio data (such as the source audio data received by step  432  or components of the source audio data extracted by step  434 ) to identify characteristics of speech included in the source audio data. In one example, step  438  may be performed in parallel to previous steps of method  430  (such as step  436  and/or step  434  and/or step  432 ), for example while the source audio data is being received and/or captured and/or generated and/or analyzed by previous steps of method  430 . In another example, step  438  may be performed after previous steps of method  430  are completed, for example after the complete source audio data was analyzed by previous steps of method  430 . 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including a rhythm of the speech. For example, duration of speech sounds may be measured. Some non-limiting examples of such speech sounds may include: vowels, consonants, syllables, utterances, and so forth. In some cases, statistics related to the duration of speech sounds may be gathered. In some examples, the variance of vowel duration may be calculated. In some examples, the percentage of speech time dedicated to one type of speech sounds may be measured. In some examples, contrasts between durations of neighboring vowels may be measured. 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including a tempo of speech. For example, speaking rate may be measured. For example, articulation rate may be measured. In some cases, the number of syllables per a unit of time may be measured, where the unit of time may include and/or exclude times of pauses, hesitations, and so forth. In some cases, the number of words per a unit of time may be measured, where the unit of time may include and/or exclude times of pauses, hesitations, and so forth. In some cases, statistics related to the rate of syllables may be gathered. In some cases, statistics related to the rate of words may be gathered. 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including a pitch of a voice. For example, pitch may be measured at specified times, randomly, continuously, and so forth. In some cases, statistics related to the pitch may be gathered. In some cases, pitch may be measured at different segments of speech, and statistics related to the pitch may be gathered for each type of segment separately. In some cases, the average speaking pitch over a time period may be calculated. In some cases, the minimal and/or maximal speaking pitch in a time period may be found. 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including loudness of the voice. For example, the loudness may be measured as the intensity of the voice. For example, loudness may be measured at specified times, randomly, continuously, and so forth. In some cases, statistics related to the loudness may be gathered. In some cases, loudness may be measured at different segments of speech, and statistics related to the loudness may be gathered for each type of segment separately. In some cases, the average speaking loudness over a time period may be calculated. In some cases, the minimal and/or maximal speaking loudness in a time period may be found. 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including intonation of the voice. For example, the pitch of the voice may be analyzed to identify rising and falling intonations. In another example, rising intonation, falling intonation, dipping intonation, and/or peaking intonation may be identified. For example, intonation may be identified at specified times, randomly, continuously, and so forth. In some cases, statistics related to the intonation may be gathered. 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including linguistic tone associated with a portion of the audio data. For example, the usage of pitch to distinguish and/or inflect words, to express emotional and/or paralinguistic information, to convey emphasis, contrast, and so forth, may be identified. 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including stress of the voice. For example, loudness of the voice and/or vowels length may be analyzed to identify an emphasis given to a specific syllable. In another example, loudness of the voice and pitch may be analyzed to identify emphasis on specific words, phrases, sentences, and so forth. In an additional example, loudness, vowel length, articulation of vowels, pitch, and so forth may be analyzed to identify emphasis associated with a specific time of speaking, with specific portions of speech, and so forth. 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including characteristics of pauses within the speech. For example, length of pauses may be measured. In some cases, statistics related to the length of pauses may be gathered. 
     In some examples, step  438  may identify characteristics of speech included in the source audio data including timbre of the voice. For example, voice brightness may be identified. As another example, formant structure associated with the pronunciation of the different sounds may be identified. 
     In some embodiments, step  440  may comprise transforming at least part of the speech from source audio data (such as the source audio data received by step  432 ). For example, step  440  may translate the speech. In another example, step  440  may transform the speech to a speech in another language register. For example, step  440  may transform all speech produced by particular one or more speakers (such as one or more speakers of the speakers identified by step  436 ) in the source audio data. In another example, step  440  may transform all speech included in one or more particular components (such as one or more particular components extracted by step  434 ) of the source audio data. In some examples, step  440  may obtain textual or other representation of speech to be transformed (for example, using transcript processing module  404 ), analyze the obtained textual or other representation, and transform at least part of the textual or other representation. Some non-limiting examples of such representation of speech may include textual representation, digital representations, representations created by artificial intelligent, and so forth. For example, step  440  may translate the at least part of the textual or other representation. In another example, step  440  may transform the at least part of the textual or other representation to another language register. For example, step  440  may transform portions of the obtained textual or other representation that corresponds to one or more particular speakers, may transform the entire obtained textual or other representation, and so forth. In some examples, step  440  may transform speech or representation of speech, for example step  440  may take as input any type of representation of speech (including audio data, textual information, or other kind of representation of speech), and may output any type of representation of speech (including audio data, textual information, or other kind of representation of speech). The types of representation of the input and output of step  440  may be identical or different. In one example, step  440  may analyze the source audio data to obtain textual information (for example using speech recognition algorithms, using transcript processing module  404 , etc.), and transform the obtained textual information. In another example, step  440  may analyze the source audio data to obtain any kind of representation of the speech included in the source audio data (for example using speech recognition algorithms), and transform the speech represented by the obtained representation. In yet another example, step  440  may analyze the textual information to obtain any kind of representation of the textual information (for example using Natural Language Processing algorithms), and transform the textual information represented by the obtained representation. In one example, step  440  may be performed in parallel to previous steps of method  430  (such as step  438  and/or step  436  and/or step  434  and/or step  432 ), for example while the source audio data is being received and/or captured and/or generated and/or analyzed by previous steps of method  430 . In another example, step  440  may be performed after previous steps of method  430  are completed, for example after the complete source audio data was analyzed by previous steps of method  430 . 
     In some examples, step  440  may base the transformation of the at least part of the speech and/or the at least part of the textual or other representation on additional information, for example based on breakdown of the source audio data to different components (for example, by step  434 ), based on identity of speakers that produced the speech (for example, based on speakers identified by step  436 ), based on characteristics of the speech (for example, based on characteristics identified by step  438 ), and so forth. Some non-limiting examples of such characteristics of speech may include characteristics of the voice of the speaker while producing the speech or parts of the speech (such as prosodic characteristics of the voice, characteristics of the pitch of the voice, characteristics of the loudness of the voice, characteristics of the intonation of the voice, characteristics of the stress of the voice, characteristics of the timbre of the voice, characteristics of the flatness of the voice, etc.), characteristics of the articulation of at least part of the speech, characteristics of speech rhythm, characteristics of speech tempo, characteristics of a linguistic tone of the speech, characteristics of pauses within the speech, characteristics of an accent of the speech (such as type of accent), characteristics of a language register of the speech, characteristics of a language of the speech, and so forth. Some additional non-limiting examples of such characteristics of speech may include a form of the speech (such as a command, a question, a statement, etc.), characteristics of the emotional state of the speaker while producing the speech, whether the speech includes one or more of irony, sarcasm, emphasis, contrast, focus, and so forth. For example, step  440  may transform the speech corresponding to a first component of the source audio data using a first transformation and/or a first parameter, and may transform the speech corresponding to a second component of the source audio data using a second transformation and/or a second parameter (the first transformation may differ from the second transformation, and the first parameter may differ from the second parameter). In another example, in response to a portion of speech being associated with a first identity of a speaker, step  440  may transform the portion of speech using a first transformation and/or a first parameter, and may in response to the portion of speech being associated with a second identity of a speaker, step  440  may transform the portion of speech using a second transformation and/or a second parameter (the first transformation may differ from the second transformation, and the first parameter may differ from the second parameter). In yet another example, in response to a portion of speech being associated with a first characteristic of the speech (for example, as identified by step  438 ), step  440  may transform the portion of speech using a first transformation and/or a first parameter, and may in response to the portion of speech being associated with a second characteristic of the speech, step  440  may transform the portion of speech using a second transformation and/or a second parameter (the first transformation may differ from the second transformation, and the first parameter may differ from the second parameter). 
     In some examples, step  440  may use Natural Language Processing (NLP) algorithms to transform the at least part of the speech and/or the at least part of the textual or other representation. For example, such algorithm may include one or more parameters to control the transformation. In some examples, a machine learning model may be trained using training examples to transform speech and/or textual information and/or other representations of speech, and step  440  may use the trained machine learning model to transform the at least part of the speech from the source audio data and/or the at least part of the textual or other representation. One example of such training example may include audio data that includes speech, together with a desired transformation of the included speech. Another example of such training example may include textual information, together with a desired transformation of the textual information. Yet another example of such training example may include other representation of speech, together with a desired transformation of the represented information. Some non-limiting examples of such desired transformations may include translation, changing of language register, and so forth. In some examples, an artificial neural network (such as recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to transform speech and/or textual information and/or other representations of speech, and step  440  may use the artificial neural network to transform the at least part of the speech from the source audio data and/or the at least part of the textual or other representation. In some examples, step  440  may use one or more of step  706 , step  1110 , step  1208 , step  1308 , step  1408 , step  1508 , step  1808 , step  1908 , step  2006 , step  2106 , step  2206 , step  2406 , step  2508  and step  2606  to transform speech and/or textual information and/or other representations of speech. Additionally or alternatively, step  440  may receive a translated and/or transformed version of the speech and/or textual information and/or other representations of speech, for example by reading the translated and/or transformed version from memory, by receiving the translated and/or transformed version from an external device, by receiving the translated and/or transformed version from a user, and so forth. 
     In some embodiments, step  442  may comprise receiving voice profiles. For example, the received voice profiles may correspond to particular speakers and/or particular audio data components (for example, to particular components of the source audio data and/or to particular desired components of a desired target audio data). For example, step  442  may read voice profiles from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive voice profiles from an external device (for example through communications network  140 ), may generate voice profiles based on audio data (for example, based on audio data including speech produced by particular speakers, based on the source audio data, based on components of the source audio data), and so forth. In some examples, step  442  may select the voice profiles from a plurality of alternative voice profiles. For example, step  442  may analyze a component of the source audio data to select a voice profile of the plurality of alternative voice profiles that is most compatible to the voice profile of a speaker in the component of the source audio data. In another example, step  442  may receive an indication from a user or from another process, and may select a voice profile of the plurality of alternative voice profiles based on the received indication. Such indication may include an indication of a particular voice profile of the plurality of alternative voice profiles to be selected, may include an indication of a desired characteristic of the selected voice profile and step  442  may select a voice profile of the plurality of alternative voice profiles that is most compatible to the desired characteristic, and so forth. 
     In some examples, step  442  may analyze audio data (such as the source audio data or a component of the source audio data) to generate the voice profiles. For example, step  442  may analyze the source audio data or the component of the source audio data to determine characteristics of a voice of a speaker producing speech in the source audio data or the component of the source audio data, and the voice profile may be based on the determined characteristics of the voice. In another example, step  442  may analyze the historic audio recordings or components of historic audio recordings to determine characteristics of a voice of a speaker producing speech in the historic audio data or the component of the historic audio data, and the voice profile may be based on the determined characteristics of the voice. In some examples, step  442  may mix a plurality of voice profiles to generate a new voice profile. For example, a first characteristic in the new voice profile may be taken from a first voice profile of the plurality of voice profiles, and a second characteristic in the new voice profile may be taken from a second voice profile (different from the first voice profile) of the plurality of voice profiles. In another example, a characteristic in the new voice profile may be a function of characteristics in the plurality of voice profiles. Some non-limiting examples of such functions may include mean, median, mode, sum, minimum, maximum, weighted average, a polynomial function, and so forth. In some examples, step  442  may receive an indication of a desired value of at least one characteristic in the voice profile from a user, from a different process, from an external device, and so forth, and set the value of at least one characteristic in the voice profile based on the received indication. In some examples, step  442  may use one or more of step  708 , step  810 , step  908 , step  910 , step  1004 , step  1006 , step  1108 , step  1210 , step  1310 , step  1410 , step  1510 , step  1610 , step  1710 , step  1810 , step  1910 , step  2008 , step  2108 , step  2208 , step  2308 , step  2410 , step  2510  and step  2610  to obtain voice profiles. 
     In some embodiments, a voice profile (such as a voice profile received and/or selected and/or generated by step  442 , a voice profile received and/or selected and/or generated by step  2208 ) may include typical characteristics of a voice (such as characteristics of a voice of a speaker), may include different characteristics of a voice in different contexts, and so forth. For example, a voice profile may specify first characteristics of a voice of a speaker for a first context, and second characteristics of the voice of the speaker for a second context, the first characteristics differ from the second characteristics. Some non-limiting examples of such contexts may include particular emotional states of the speaker, particular form of speech (such as a command, a question, a statement, etc.), particular linguistic tones, particular topics of speech or conversation, particular conversation partners, characteristics of conversation partners, number of participants in a conversation, geographical location, time in day, particular social activities, context identified using step  468  (described below), and so forth. Some non-limiting examples of such characteristics of a voice that may be specified in a voice profile may include prosodic characteristics of the voice, characteristics of the pitch of the voice, characteristics of the loudness of the voice, characteristics of the intonation of the voice, characteristics of the stress of the voice, characteristics of the timbre of the voice, characteristics of the flatness of the voice, characteristics of the articulation of words and utterances, characteristics of speech rhythm, characteristics of speech tempo, characteristics of pauses within the speech, characteristics of an accent of the speech (such as type of accent), and so forth. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first emotional state of the speaker, and second characteristics of the voice of the speaker for a second emotional state of the speaker, the first characteristics differ from the second characteristics. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first form of speech, and second characteristics of the voice of the speaker for a second form of speech, the first characteristics differ from the second characteristics. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first topic of speech or conversation, and second characteristics of the voice of the speaker for a second topic of speech or conversation, the first characteristics differ from the second characteristics. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first linguistic tone, and second characteristics of the voice of the speaker for a second linguistic tone, the first characteristics differ from the second characteristics. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first group of conversation partners, and second characteristics of the voice of the speaker for a second group of conversation partners, the first characteristics differ from the second characteristics. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first number of participants in a conversation, and second characteristics of the voice of the speaker for a second number of participants in a conversation, the first characteristics differ from the second characteristics. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first geographical location, and second characteristics of the voice of the speaker for a second geographical location, the first characteristics differ from the second characteristics. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first time in day, and second characteristics of the voice of the speaker for a second time in day, the first characteristics differ from the second characteristics. In one example, a voice profile may specify first characteristics of a voice of a speaker for a first social activity, and second characteristics of the voice of the speaker for a second social activity, the first characteristics differ from the second characteristics. 
     In some embodiments, step  444  may comprise generating speech data. In some examples, step  444  may obtain audible, textual or other representation of speech, and generate speech data corresponding to the obtained audible, textual or other representation of speech. For example, step  444  may generate audio data including the generated speech data. In another example, step  444  may generate speech data in any format that is configured to enable step  446  to synthesis target audio data that includes the speech. In one example, step  444  may obtain the audible, textual or other representation of speech from step  440 . In another example, step  444  may read the audible, textual or other representation of speech from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive the audible, textual or other representation of speech from an external device (for example through communications network  140 ), and so forth. 
     In some examples, step  444  may use any Text To Speech (TTS) or speech synthesis algorithm or system to generate the speech data. Some non-limiting examples of such algorithms may include concatenation synthesis algorithms (such as unit selection synthesis algorithms, diphone synthesis algorithms, domain-specific synthesis algorithms, etc.), formant algorithms, articulatory algorithms, Hidden Markov Models algorithms, Sinewave synthesis algorithms, deep learning based synthesis algorithms, and so forth. In one example, step  444  may be performed in parallel to previous steps of method  430  (such as step  440  and/or step  438  and/or step 436 and/or step  434  and/or step  432 ), for example while the source audio data is being received and/or captured and/or generated and/or analyzed by previous steps of method  430 . In another example, step  444  may be performed after previous steps of method  430  are completed, for example after the complete source audio data was analyzed by previous steps of method  430 . 
     In some examples, step  444  may base the generation of speech data on a voice profile (such as a voice profile received and/or selected and/or generated by step  442 ). For example, the generated speech data may include speech in a voice corresponding to the voice profile (for example, a voice having at least one characteristic specified in the voice profile). For example, the voice profile may include typical characteristics of a voice, and step  444  may generate speech data that includes speech in a voice corresponding to these typical characteristics. In another example, the voice profile may include different characteristics of a voice for different contexts, step  444  may select characteristics of a voice corresponding to a particular context corresponding to the speech, and step  444  may further generate speech data that includes speech in a voice corresponding to the selected characteristics. Some non-limiting examples of such selected characteristics or typical characteristics may include prosodic characteristics of a voice, characteristics of a pitch of a voice, characteristics of a loudness of a voice, characteristics of an intonation of a voice, characteristics of a stress of a voice, characteristics of a timbre of a voice, characteristics of a flatness of a voice, characteristics of an articulation, characteristics of a speech rhythm, characteristics of a speech tempo, characteristics of a linguistic tone, characteristics of pauses within a speech, characteristics of an accent (such as type of accent), and so forth. 
     In some examples, step  444  may base the generation of speech data on desired voice characteristics and/or desired speech characteristics. For example, the desired voice characteristics and/or desired speech characteristics may be based on characteristics identified by step  438 , on characteristics provided by a user, on characteristics provided by an external device, on characteristics read from memory, determined based on the content of the speech, determined based on context, and so forth. For example, step  444  may generate speech data that includes speech in a voice corresponding to the desired characteristics. Some non-limiting examples of such voice characteristics may include prosodic characteristics of a voice, characteristics of a pitch of a voice, characteristics of a loudness of a voice, characteristics of an intonation of a voice, characteristics of a stress of a voice, characteristics of a timbre of a voice, characteristics of a flatness of a voice, characteristics of an articulation, characteristics of an accent (such as type of accent), and so forth. Some non-limiting examples of such speech characteristics may include characteristics of a speech rhythm, characteristics of a speech tempo, characteristics of a linguistic tone, characteristics of pauses within a speech, and so forth. 
     In some examples, a machine learning model may be trained using training example to generate speech data (or generate audio data including the speech data) from textual or other representations of speech and/or voice profiles and/or desired voice characteristics and/or desired speech characteristics, and step  444  may use the trained machine learning model to generate the speech data (or audio data including the speech data) based on the voice profile and/or on the desired voice characteristics and/or on the desired speech characteristics. An example of such training example may include textual or other representations of speech and/or a voice profile and/or desired voice characteristics and/or desired speech characteristics, together with desired speech data (or audio data including the desired speech data). For example, the desired speech data may include data of one or more utterances. In some examples, an artificial neural network may be configured to generate speech data (or generate audio data including the speech data) from textual or other representations of speech and/or voice profiles and/or desired voice characteristics and/or desired speech characteristics, and step  444  may use the artificial neural network to generate the speech data (or audio data including the speech data) based on the voice profile and/or on the desired voice characteristics and/or on the desired speech characteristics. In some examples, Generative Adversarial Networks (GAN) may be used to train an artificial neural network configured to generate speech data (or generate audio data including the speech data) corresponding to voice profiles and/or desired voice characteristics and/or desired speech characteristics, for example from textual or other representations of speech, and step  444  may use the trained artificial neural network to generate the speech data (or audio data including the speech data) based on the voice profile and/or on the desired voice characteristics and/or on the desired speech characteristics. 
     Additionally or alternatively, step  444  may generate non-verbal audio data, for example audio data of non-verbal vocalizations (such as laughter, giggling, sobbing, crying, weeping, cheering, screaming, inhalation noises, exhalation noises, and so forth). For example, the voice profile and/or the desired voice characteristics may include characteristics of such non-verbal vocalizations, and step  444  may generate non-verbal audio data corresponding to the included characteristics of non-verbal vocalizations. 
     In some examples, a machine learning model may be trained using training example to generate speech data (or generate audio data including the speech data) from source audio data including speech and voice profiles, and step  444  may use the trained machine learning model to generate the speech data (or different audio data including the speech data) in a voice corresponding to the voice profile. An example of such training example may include source audio data including speech and a voice profile, together with desired speech data (or different audio data including the desired speech data). In some examples, an artificial neural network may be configured to generate speech data (or generate audio data including the speech data) from source audio data including speech and voice profiles, and step  444  may use the artificial neural network to generate the speech data (or different audio data including the speech data) a voice corresponding to the voice profile. For example, step  444  may use the trained machine learning model and/or the artificial neural network to transform source audio data (or components of source audio data) from original voice to a voice corresponding to the voice profile. 
     In some embodiments, step  446  may comprise synthesizing target audio data. For example, step 446 may synthesize target audio data from speech data (or audio data including the speech data) generated by step  444 , from non-verbal audio data generated by step  444 , from components of the source audio data extracted by step  434 , from audio streams obtained from other sources, and so forth. For example, step  446  may mix, merge, blend and/or stitch different sources of audio into a single target audio data, for example using audio mixing algorithms and/or audio stitching algorithms. In some examples, step  446  may mix, merge, blend and/or stitch the different sources of audio in accordance to a particular arrangement of the different sources of audio. For example, the particular arrangement may be specified by a user, may be read from memory, may be received from an external device, may be selected (for example, may be selected to correspond to an arrangement of sources and/or information in the source audio data received by step  432 ), and so forth. In one example, step  446  may be performed in parallel to previous steps of method  430  (such as step  444  and/or step  440  and/or step  438  and/or step  436  and/or step  434  and/or step  432 ), for example while the source audio data is being received and/or captured and/or generated and/or analyzed by previous steps of method  430 . In another example, step  446  may be performed after previous steps of method  430  are completed, for example after the complete source audio data was analyzed by previous steps of method  430 . 
     Additionally or alternatively to step  444  and/or step  446 , method  430  may use one or more of step  710 , step  712 , step  812 , step  912 , step  1012 , step  1112 , step  1212 , step  1312 , step  1412 , step  1512 , step  1612 , step  1712 , step  1812 , step  1912 , step  2012 , step  2112 , step  2212 , step  2312 ,  2412 , step  2512  and step  2612  to generate the target audio data. 
     In some embodiments, step  448  may comprise outputting audio data, for example outputting the target audio data synthesized by step  446 . For example, step  448  may use the audio data to generate sounds that corresponds to the audio data, for example using audio subsystem  226  and/or speaker  228 . In another example, step  448  may store the audio data in memory (for example, in data structure  126 , in data structure  136 , in memory  250 , in memory  320 , in memory  400 , etc.), may provide the audio data to an external device (for example through communications network  140 ), may provide the audio data to a user, may provide the audio data to another process (for example, to a process implementing any of the methods and/or steps and/or techniques described herein), and so forth. In yet another example, step  448  may insert the audio data to a video. 
       FIG.  4 C  is a flowchart of an example method  430  for video manipulation. In this example, method  460  may comprise: receiving source video data (step  462 ); detecting elements depicted in the source video data (step  464 ); identifying properties of elements depicted in the source video data (step  466 ); identifying contextual information (step  468 ); generating target video (step  470 ); and outputting target video (step  472 ). In some implementations, method  460  may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. In some implementations, one or more steps illustrated in  FIG.  4 C  may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. 
     In some embodiments, step  462  may comprise receiving source video data. In some examples, step  462  may read source video data from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive source video data from an external device (for example through communications network  140 ), may receive source video data using media receipt module  402 , may capture source video data using one or more image sensors (for example, using camera subsystem  220  and/or optical sensor  222 ), and so forth. In some examples, the source video data may be received in any suitable format. Some non-limiting examples of such formats may include uncompressed video formats, lossless compressed video formats, lossy compressed video formats, and so forth. In one example, the received source video data may include audio data. In another example, the received source video data may include no audio data. In one example, step  462  may receive source video data that is recorded from an environment. In another example, step  462  may receive source video data that is artificially synthesized. In one example, step  462  may receive the source video data after the recording of the source video data was completed. In another example, step  462  may receive the source video data in real-time, while the source video data is being produced and/or recorded. In some examples, step  462  may use one or more of step  702 , step  902 , step  802 , step  1002 , step  1102 , step  1202 , step  1302 , step  1402 , step  1502 , step  1602 , step  1702 , step  1802 , step  1902 , step  2002 , step  2102 , step  2202 , step  2302 , step  2402 , step  2502 , step  2602 , step  2902 , step  3002 , step  3102 , step  3202 , step  3302  and step  3402  to obtain the source video data. 
     In some embodiments, step  464  may comprise detecting elements depicted in video data, for example detecting elements depicted in the source video data received by step  462 . For example, step  464  may determine whether an element of a particular type is depicted in the video data. In another example, step  464  may determine the number of elements of a particular type that are depicted in the video data. In some examples, step  464  may identify a position of an element of a particular type is depicted in the video data. For example, step  464  may identify one or more frames of the video data that depicts the element. In another example, step  464  may identify position of the element in a frame of the video data. For example, step  464  may identify a bounding shape (such as a bounding box, a bounding polygon, etc.) corresponding to the position of the element in the frame, a position corresponding to the depiction of the element in the frame (for example, a center of the depiction of the element, a pixel within the depiction of the element, etc.), the pixels comprising the depiction of the element in the frame, and so forth. Some non-limiting examples of such elements may include objects, animals, persons, faces, body parts, actions, events, and so forth. Some non-limiting examples of such types of elements may include particular types of objects, particular types of animals, persons, faces, particular body parts, a particular person (or a particular body part of a particular person, such as face of the a particular person), particular types of actions, particular types of events, and so forth. In some examples, to detect elements depicted in the video data (or to detect elements of a particular type in the video data), step  464  may analyze the video data using object detection algorithms, face detection algorithms, pose estimation algorithms, person detection algorithms, action detection algorithms, event detection algorithms, and so forth. In some examples, a machine learning model may be trained using training examples to detect elements of particular types in videos, and step  464  may use the trained machine learning model to analyze the video data and detect the elements. An example of such training example may include video data, together with an indication of the elements depicted in the video data and/or the position of the elements in the video data. In some examples, an artificial neural network (such as convolutional neural network, deep neural network, etc.) may be configured to detect elements of particular types in videos, and step  464  may use the artificial neural network to analyze the video data and detect the elements. In one example, step  464  may be performed in parallel to previous steps of method  460  (such as step  462 ), for example while the source video data is being received and/or captured and/or generated and/or analyzed by previous steps of method  460 . For example, step  464  may analyze some frames of the source video data before other frames of the source video data are received and/or captured and/or generated and/or analyzed. In another example, step  464  may be performed after previous steps of method  460  are completed, for example after the complete source video data was received and/or captured and/or generated and/or analyzed by previous steps of method  460 . 
     In some embodiments, step  466  may comprise identifying properties of elements depicted in video data, for example identify properties of elements depicted in the source video data received by step  462 . For example, step  466  may identify properties of elements detected by step  464  in the video data. In some examples, step  466  may identify visual properties of the elements. Some non-limiting examples of such visual properties may include dimensions (such as length, height, width, size, in pixels, in real world, etc.), color, texture, and so forth. For example, to determine the visual properties, step  466  may analyze the pixel values of the depiction of the element in the video data, may count pixels within the depiction of the element in the video data, may analyze the video data using filters, and so forth. In some examples, step  466  may identify whether an element belong to a particular category of elements. For example, the element may be an animal and the particular category may include a taxonomy category of animals, the element may be a product and the particular category may include a particular brand, the element may be a person and the particular category may include a demographic group of people, the element may include an event and the particular category may include a severity group for the event, and so forth. For example, to identify whether the element belong to a particular category of elements, step  466  may use classification algorithms to analyze the depiction of the element in the video data. In some examples, step  466  may identify a pose of an element, for example using a pose estimation algorithm to analyze the depiction of the element in the video data. In some examples, step  466  may identify identities of the elements. For example, the element may be a person or associated with a particular person and step  466  may identify a name or a unique identifier of the person, the element may be an object and step  466  may identify a serial number or a unique identifier of the object, and so forth. For example, to identify an identity of an element, step  466  may analyze the video data using face recognition algorithms, object recognition algorithms, serial number and/or visual codes reading algorithms, and so forth. In some examples, step  466  may identify numerical properties of the elements. Some non-limiting examples of such numerical properties may include estimated weight of an object, estimated volume of an object, estimated age of a person or an animal, and so forth. For example, to identify numerical properties of an element, step  466  may use regression algorithms to analyze the depiction of the element in the video data. In one example, a machine learning model may be trained using training examples to identify properties of elements from video data, and step  466  may use the trained machine learning model to analyze the video data and identify properties of an element. An example of such training example may include video data depicting an element, together with an indication of particular properties of the depicted element. In another example, an artificial neural network (such as convolutional neural network, deep neural network, etc.) may be configured to identify properties of elements from video data, and step  466  may use the artificial neural network to analyze the video data and identify properties of an element. In one example, step  466  may be performed in parallel to previous steps of method  460  (such as step  464  and/or step  462 ), for example while the source video data is being received and/or captured and/or generated and/or analyzed by previous steps of method  460 . For example, step  466  may analyze some frames of the source video data before other frames of the source video data are received and/or captured and/or generated and/or analyzed. In another example, step  466  may be performed after previous steps of method  460  are completed, for example after the complete source video data was received and/or captured and/or generated and/or analyzed by previous steps of method  460 . In some examples, steps  464  and  466  may be performed together as a single step, while in other examples steps  466  may be performed separately from step  464 . 
     In some embodiments, step  468  may comprise identifying contextual information. In some examples, step  468  may analyze video data (such as the source video data received by step  462 ) and/or audio data (such as the source audio data received by step  432 ) and/or data captured using other sensors to identify the contextual information. For example, a machine learning model may be trained using training examples to identify contextual information from video data and/or audio data and/or data from other sensors, and step  468  may use the trained machine learning model to analyze the video data and/or audio data and/or the data captured using other sensors to identify the contextual information. An example of such training example may include video data and/or audio data and/or data from other sensors, together with corresponding contextual information. In one example, the audio data may include speech (such as one or more conversation), step  468  may analyze the speech (for example using NLP algorithms) to determine one or more topics and/or one or more keywords, and the contextual information may include and/or be based on the determined one or more topics and/or one or more keywords. In one example, step  468  may analyze the video data to determine a type of cloths wore by people in the scene, and the contextual information may include and/or be based on the determined type of cloths. In one example, step  468  may determine a location (for example, based on input from a positioning sensor, based on an analysis of video data, etc.), and the contextual information may include and/or be based on the determined location. In one example, step  468  may determine a time (for example, based on input from a clock, based on an analysis of video data to determine part of day, etc.), and the contextual information may include and/or be based on the determined time. In one example, step  468  may analyze the video data to determine presence of objects in an environment and/or to determine the state of objects in an environment, and the contextual information may be based on the objects and/or a state of the objects. In one example, step  468  may analyze the video data and/or the audio data to identify people in an environment, and the contextual information may be based on the identified persons. In one example, step  468  may analyze the video data and/or the audio data to detect actions and/or events occurring in an environment, and the contextual information may be based on the detected actions and/or events. For example, the contextual information may include information related to location, time, settings, topics, objects, state of objects, people, actions, events, type of scene, and so forth. 
     In some embodiments, step  470  may comprise generating target video data. In some examples, step  470  may manipulate source video data (such as the source video data received by step  462 ) to generate the target video data. In some examples, step  470  may generate target video data in any suitable format. Some non-limiting examples of such formats may include uncompressed video formats, lossless compressed video formats, lossy compressed video formats, and so forth. In some examples, step  470  may generate target video data that may include audio data. For example, step  470  may use method  430  to generate the included audio data, for example based on audio data included in the source audio data received by step  462 . In another example, step  470  may generate target video data that may include no audio data. 
     In some examples, step  470  may generate the target video data (or manipulate the source video data) based on elements detected in the source video data (for example, based on the elements detected by step  464 ). For example, step  470  may manipulate the depiction of a detect element to transform the source video data to the target video data. In another example, in response to a detection of an element of a particular type in the source video data, step  470  may generate first target video data, and in response to a failure to detect elements of the particular type, step  470  may generate second target video data, the second video data may differ from the first video data. In yet another example, in response to a detection of a first number of elements of a particular type in the source video data, step  470  may generate first target video data, and in response to a detection of a second number of elements of the particular type, step  470  may generate second target video data, the second video data may differ from the first video data. In an additional example, in response to a detection of an element of a particular type at a first particular time within the source video data and/or at a first particular position within a frame of the source video data, step  470  may generate first target video data, and in response to a detection of the element of the particular type at a second particular time within the source video data and/or at a second particular position within a frame of the source video data, step  470  may generate second target video data, the second video data may differ from the first video data. 
     In some examples, step  470  may generate the target video data (or manipulate the source video data) based on properties of elements identified from the source video data (for example, based on the properties identified by step  466 ). For example, in response to a first property of an element, step  470  may generate first target video data, and in response to a second property of the element, step  470  may generate second target video data, the second video data may differ from the first video data. In an additional example, in response to a first property of an element, step  470  may apply a first manipulation function to the source video data to generate a first target video data, and in response to a second property of the element, step  470  may apply a second manipulation function to the source video data to generate a second target video data, the second manipulation function may differ from the first manipulation function, and the second target video data may differ from the first target video data. Some non-limiting examples of such properties are described above. 
     In some examples, step  470  may generate the target video data (or manipulate the source video data) based on contextual information (for example, based on the contextual information identified by step  468 ). For example, in response to first contextual information, step  470  may generate a first target video data, and in response to second contextual information, step  470  may generate a second target video data, the second target video data may differ from the first target video data. In another example, in response to first contextual information, step  470  may apply a first manipulation function to the source video data to generate a first target video data, and in response to second contextual information, step  470  may apply a second manipulation function to the source video data to generate a second target video data, the second manipulation function may differ from the first manipulation function, and the second target video data may differ from the first target video data. 
     In some example, Generative Adversarial Networks (GAN) may be used to train an artificial neural network configured to generate visual data (or generate video data including the visual data) depicting items (such as background, objects, animals, characters, people, etc.) corresponding to desired characteristics, and step  470  may use the trained artificial neural network to generate the target video or portions of the target video. 
     In some embodiments, step  472  may comprise outputting video data, for example outputting the target video data generated by step  470 . For example, step  472  may use the video data to generate visualizations that corresponds to the video data, for example using a display device, using a virtual reality system, using an augmented reality system, and so forth. In another example, step  472  may store the video data in memory (for example, in data structure  126 , in data structure  136 , in memory  250 , in memory  320 , in memory  400 , etc.), may provide the video data to an external device (for example through communications network  140 ), may provide the video data to a user, may provide the video data to another process (for example, to a process implementing any of the methods and/or steps and/or techniques described herein), and so forth. 
       FIG.  5    is a block diagram illustrating the operation of an example system  500  (e.g., artificial dubbing system  100 ) configured to generate artificial voice for a media stream. In this example, the media stream includes an audio stream (e.g., a podcast, a phone call, etc.). In some embodiments, system  500  may be suitable for real time application running on low-resource devices (e.g., communications device  160 ), where the audio is received in streaming mode and the transcript of the audio stream is being determined in real time. 
     System  500  may include an audio analysis unit  510  for receiving the original audio stream  505  and analyzing the audio stream to determine a set of voice parameters of at least one individual that speak in the audio stream. Audio analysis unit  510  may also determine a voice profile  515  of the individual based on the set of voice properties. The voice profile  515  is then passed to voice generation unit  535 . System  500  further includes a text analysis unit  525  for obtaining the original transcript  520  and receiving from the user a target language selection. In one embodiment, text analysis unit  525  may determine original transcript  520  from original audio stream  505  and automatically determine the target language selection based on user profile. 
     Text analysis unit  525  may translate the original transcript into the target language (e.g. using online translation services) and pass a translated transcript  530  to voice generation unit  535 . Voice generation unit  535  may generate a translated audio stream  540  that sounds as if the individual speaking in the target language using the translated transcript  530  and the voice profile  515 . Translated audio stream  540  may then by passed to a prosody analysis unit  545 . Prosody analysis unit  545  may use the timing of translated audio stream  540 , and the received timing of the original transcript to recommend adjustments  550  that should be done to the final dubbed voice in terms of stretching/shrinking and speed of dubbing. These adjustment recommendations are passed to a revoicing unit  555 . Revoicing unit  555  may implement the recommendations  550  on translated audio stream  540 . 
       FIG.  6    is a block diagram illustrating the operation of an example system  600  (e.g., artificial dubbing system  100 ) configured to generate artificial voice for a media stream. In this example, the media stream includes an audio stream and a video stream (e.g., YouTube, Netflix). 
     Consistent with the present disclosure, system  600  may include a pre-processing unit 605 for separating media stream  110  into separated audio stream  610  and video stream  615 . System  600  may include a media analysis unit  620  configured to receive an audio stream  610  and a video stream  615 . In another example, audio stream  610  may be received using step  432 , using media receipt module  402 , and so forth. In one embodiment, media analysis unit  620  is configured to analyze audio stream  610  to identify a set of voice properties of each individual speaking in audio stream  610  and output a unique voice profile  625  of for each individual based on the set of voice properties. In other embodiments, media analysis unit  620  is configured to analyze video stream  615  to determine video data  630  such as, characteristics of the individual, a gender of the individual, and/or a gender of a person that the individual is speaking to. In addition, system  600  may include a text analysis unit  635  for obtaining an original transcript  640  in the original language of the media stream and a target transcript  645  in the target language to which the video should be dubbed. Text analysis unit  635  may also analyze the audio stream  610  and a video stream  615  to and metadata transcript information  650 . As mentioned above, text analysis unit  635  may receive original transcript  640  and target transcript  650  from separate entity (e.g., media owner  120 ). Alternatively, text analysis unit  635  may also determine original transcript  640  and target transcript  650  from media stream  110 . 
     Voice generation unit  655  may generate a first revoiced audio stream  660  in the original language based on original transcript  640 . First revoiced audio stream  660  is artificially generated using voice profile  625 , video data  630 , and metadata transcript information  650 . Voice generation unit  655  may use machine learning modules to test the artificially generated audio stream and to improve voice profile  625  such that first revoiced audio stream  660  will sound similar to audio stream  610 . When the similarity between first revoiced audio stream  660  and audio stream  610  is greater than a similarity threshold, voice generation unit  655  may generate a second revoiced audio stream  665  in the target language based on target transcript  645 . Second revoiced audio stream  665  is artificially generated using the updated voice profile  625 , video data  630 , and metadata transcript information  650 . 
     Thereafter, voice generation unit  655  may pass the first and second revoiced audio streams to a prosody analysis unit  670 . Prosody analysis unit  670  may performs comparison of the properties of the second revoiced audio stream  665  to the properties of the first revoiced audio stream  660 . Using this comparison, prosody analysis unit  670  may recommend adjustments  675  that should be done to the final dubbed voice, including the right volume (to mimic a specific emphasis, or the overall volume of the spoken sentence), intonation (the trend of the pitch), speed, distribution of the audio (e.g., on the 5.1, or more, channels of surround audio), gender, exact speech beginning timing, etc. The intonation (speed, volume, pitch, etc.) in the original language TTS voice sound segment generated from the original language sentence may be compared to an original language’s feeling intonations library and if there is a high level of confidence of a match, a ‘feeling descriptor’ may be attached to the recommendations, in order to render the sentence with a pre-set intonation, which is based on the localized feeling/intonation library. These adjustment recommendations are passed to a revoicing unit  680 . 
     In one embodiment, prosody analysis unit  670  may suggests adjustments that should be made to the final dubbed voice, e.g. the appropriate local voice gender that should be used, the speed of speech (based on the length of the resulting audio from the local language voice audio segment compared to the timing mentioned in the transcript file and the next transcript’s timing that should not be overlapped, and/or the actual timing of the original voice in the video’s audio track, etc.), the trend of volume within the sentence (for emphasis), the trend of pitch within the sentence (for intonation), etc. It could also decide if it needs to merge a line or two (or three, etc.), based on the punctuation within the text, the timing between the lines, the switching between one actor’s voice to another, etc. Revoicing unit  680  waits until it’s the right time to ‘speak’ based on the transcript’s timing and video data  630 . For example, when translating a movie from a short duration language to a long duration language (e.g. an English movie dubbed to German) or from long to short (e.g. German to English), the target language speech audio usually needs to be time adjusted (stretched or shrunk) to fit in with the original movie’s timing. Simple homogeneous time stretching or shrinking isn’t usually good enough, and when squeezed or stretched to more than 20% from the original audio stream, distortions and artifacts might appear in the revoiced audio stream. In order to minimize these distortions, the adjustments should not be homogeneous, but rather manipulate the gaps between words on a different scale than that used on the actual said words made with voice generation unit  655 . This can be done by directing the voice generation engine to shorten or widen the gaps before pronouncing the sentence, and/or it can be done in the post process phase (by analyzing the resulting target language’s audio track signal for segments with volume lower than -60 dB, and minimizing, eliminating or widening their length by a major factor, e.g. by 80%) and then time adjusting (stretching or shrinking) the resulting audio track by a lower factor (e.g. only 10%), because the overall audio now needs less squeezing in order to fit the available movie timing. 
     Consistent with the present disclosure, revoicing unit  680  may merge the new created audio track into the original movie to create revoiced media stream  150 . In yet another embodiment of the present invention, as used for live TV broadcasts with pre-translated closed transcript, the video playback may be continuously delayed for approximately one minute, during the entire broadcast. During the delay, a standard Speech-to-Text module is run, to regenerate the text lines from audio stream  610 , and compare with the translated closed transcript. Once the original language transcript line is generated, the analysis is performed and the delayed video is dubbed. In yet another embodiment, the pre-translated transcript may be replaced by sending the closed transcript to a local translation unit, or by using a remote translation unit (e.g. online translation services). In addition, the original language transcript file may be determined by a speech recognition module that transcribes the video segment from the beginning of the timing of the next transcript till the end of it (as marked in the translated language transcript file). In yet another embodiment, the local language transcript file may be replaced by closed captions ‘burned’ on the video. The captions are provided to an Optical Character Recognition (OCR) engine to recognize the text on the screen, which is then transcribed and time-stamped. In yet another embodiment, the video may comprises ‘burned’ closed captions in a language other than the local language. The captions are provided to an OCR engine to recognize the text on the screen, which is then transcribed, time-stamped, translated and dubbed. 
     In some embodiments, a method (such as methods  430 ,  460 ,  700 ,  800 ,  900 ,  1000 ,  1100 ,  1200 ,  1300 ,  1400 ,  1500 ,  1600 ,  1700 ,  1800 ,  1900 ,  2000 ,  2100 ,  2200 ,  2300 ,  2400 ,  2500 ,  2600 ,  2900 ,  3000 ,  3100 ,  3200 ,  3300 ,  3400 ,  3500 ,  3600 ,  3700 ,  3800 , etc.) may comprise of one or more steps. In some examples, a method, as well as all individual steps therein, may be performed by various aspects of revoicing unit  130 , server  123 , server  133 , communications devices  160 , and so forth. For example, the method may be performed by processing units (such as processors  204 ) executing software instructions stored within memory units (such as memory  250 ). In some examples, a method, as well as all individual steps therein, may be performed by a dedicated hardware. In some examples, computer readable medium (such as a non-transitory computer readable medium) may store data and/or computer implementable instructions for carrying out a method. Some non-limiting examples of possible execution manners of a method may include continuous execution (for example, returning to the beginning of the method once the method normal execution ends), periodically execution, executing the method at selected times, execution upon the detection of a trigger (some non-limiting examples of such trigger may include a trigger from a user, a trigger from another method, a trigger from an external device, etc.), and so forth. 
     In some embodiments, machine learning algorithms (also referred to as machine learning models in the present disclosure) may be trained using training examples, for example in the cases described below. Some non-limiting examples of such machine learning algorithms may include classification algorithms, data regressions algorithms, image segmentation algorithms, visual detection algorithms (such as object detectors, face detectors, person detectors, motion detectors, edge detectors, etc.), visual recognition algorithms (such as face recognition, person recognition, object recognition, etc.), speech recognition algorithms, mathematical embedding algorithms, natural language processing algorithms, support vector machines, random forests, nearest neighbors algorithms, deep learning algorithms, artificial neural network algorithms, convolutional neural network algorithms, recurrent neural network algorithms, linear algorithms, non-linear algorithms, ensemble algorithms, and so forth. For example, a trained machine learning algorithm may comprise an inference model, such as a predictive model, a classification model, a regression model, a clustering model, a segmentation model, an artificial neural network (such as a deep neural network, a convolutional neural network, a recurrent neural network, etc.), a random forest, a support vector machine, and so forth. In some examples, the training examples may include example inputs together with the desired outputs corresponding to the example inputs. Further, in some examples, training machine learning algorithms using the training examples may generate a trained machine learning algorithm, and the trained machine learning algorithm may be used to estimate outputs for inputs not included in the training examples. In some examples, engineers, scientists, processes and machines that train machine learning algorithms may further use validation examples and/or test examples. For example, validation examples and/or test examples may include example inputs together with the desired outputs corresponding to the example inputs, a trained machine learning algorithm and/or an intermediately trained machine learning algorithm may be used to estimate outputs for the example inputs of the validation examples and/or test examples, the estimated outputs may be compared to the corresponding desired outputs, and the trained machine learning algorithm and/or the intermediately trained machine learning algorithm may be evaluated based on a result of the comparison. In some examples, a machine learning algorithm may have parameters and hyper parameters, where the hyper parameters are set manually by a person or automatically by an process external to the machine learning algorithm (such as a hyper parameter search algorithm), and the parameters of the machine learning algorithm are set by the machine learning algorithm according to the training examples. In some implementations, the hyper-parameters are set according to the training examples and the validation examples, and the parameters are set according to the training examples and the selected hyper-parameters. 
     In some embodiments, trained machine learning algorithms (also referred to as trained machine learning models in the present disclosure) may be used to analyze inputs and generate outputs, for example in the cases described below. In some examples, a trained machine learning algorithm may be used as an inference model that when provided with an input generates an inferred output. For example, a trained machine learning algorithm may include a classification algorithm, the input may include a sample, and the inferred output may include a classification of the sample (such as an inferred label, an inferred tag, and so forth). In another example, a trained machine learning algorithm may include a regression model, the input may include a sample, and the inferred output may include an inferred value for the sample. In yet another example, a trained machine learning algorithm may include a clustering model, the input may include a sample, and the inferred output may include an assignment of the sample to at least one cluster. In an additional example, a trained machine learning algorithm may include a classification algorithm, the input may include an image, and the inferred output may include a classification of an item depicted in the image. In yet another example, a trained machine learning algorithm may include a regression model, the input may include an image, and the inferred output may include an inferred value for an item depicted in the image (such as an estimated property of the item, such as size, volume, age of a person depicted in the image, cost of a product depicted in the image, and so forth). In an additional example, a trained machine learning algorithm may include an image segmentation model, the input may include an image, and the inferred output may include a segmentation of the image. In yet another example, a trained machine learning algorithm may include an object detector, the input may include an image, and the inferred output may include one or more detected objects in the image and/or one or more locations of objects within the image. In some examples, the trained machine learning algorithm may include one or more formulas and/or one or more functions and/or one or more rules and/or one or more procedures, the input may be used as input to the formulas and/or functions and/or rules and/or procedures, and the inferred output may be based on the outputs of the formulas and/or functions and/or rules and/or procedures (for example, selecting one of the outputs of the formulas and/or functions and/or rules and/or procedures, using a statistical measure of the outputs of the formulas and/or functions and/or rules and/or procedures, and so forth). 
     In some embodiments, artificial neural networks may be configured to analyze inputs and generate corresponding outputs. Some non-limiting examples of such artificial neural networks may comprise shallow artificial neural networks, deep artificial neural networks, feedback artificial neural networks, feed forward artificial neural networks, autoencoder artificial neural networks, probabilistic artificial neural networks, time delay artificial neural networks, convolutional artificial neural networks, recurrent artificial neural networks, long short term memory artificial neural networks, and so forth. In some examples, an artificial neural network may be configured manually. For example, a structure of the artificial neural network may be selected manually, a type of an artificial neuron of the artificial neural network may be selected manually, a parameter of the artificial neural network (such as a parameter of an artificial neuron of the artificial neural network) may be selected manually, and so forth. In some examples, an artificial neural network may be configured using a machine learning algorithm. For example, a user may select hyper-parameters for the an artificial neural network and/or the machine learning algorithm, and the machine learning algorithm may use the hyper-parameters and training examples to determine the parameters of the artificial neural network, for example using back propagation, using gradient descent, using stochastic gradient descent, using mini-batch gradient descent, and so forth. In some examples, an artificial neural network may be created from two or more other artificial neural networks by combining the two or more other artificial neural networks into a single artificial neural network. 
     In some embodiments, analyzing audio data (for example, by the methods, steps and modules described herein) may comprise analyzing the audio data to obtain a preprocessed audio data, and subsequently analyzing the audio data and/or the preprocessed audio data to obtain the desired outcome. One of ordinary skill in the art will recognize that the followings are examples, and that the audio data may be preprocessed using other kinds of preprocessing methods. In some examples, the audio data may be preprocessed by transforming the audio data using a transformation function to obtain a transformed audio data, and the preprocessed audio data may comprise the transformed audio data. For example, the transformation function may comprise a multiplication of a vectored time series representation of the audio data with a transformation matrix. For example, the transformation function may comprise convolutions, audio filters (such as low-pass filters, high-pass filters, band-pass filters, all-pass filters, etc.), nonlinear functions, and so forth.

In one example the virtual entity sounds similar to the individual in the original media stream. The method includes determining a synthesized voice for a virtual entity intended to dub the individual in the original media stream. The synthesized voice may have one or more characteristics identical to the characteristics of the particular voice. Consistent with the present disclosure, method  700  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  700 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including an individual speaking in an origin language, wherein the individual is associated with particular voice. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  702 , the processing device may receive a media stream including an individual speaking in an origin language, wherein the individual is associated with particular voice. For example, step  702  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the media stream including utterances spoken in the origin language. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  704 , the processing device may obtain a transcript of the media stream including utterances spoken in the origin language. 
     The disclosed embodiment may further include translating the transcript of the media stream to a target language, wherein the translated transcript includes a set of words in the target language for each of at least some of the utterances spoken in the origin language. As mentioned above, transcript processing module  404  may include instructions to translate the transcript of the received media stream to the target language using any suitable translation algorithm. According to step  706 , the processing device may translate the transcript of the media stream to a target language, wherein the translated transcript may include a set of words in the target language for each of at least some of the utterances spoken in the origin language. For example, step  706  may use step  440  to translate or otherwise transform the transcript. In one example, step  706  may translate or transformed speech directly from the media stream received by step  702 , for example as described above in relation to step  440 , and step  704  may be excluded from method  700 . Additionally or alternatively, step  706  may receive a translated transcript, for example by reading the translated transcript from memory, by receiving the translated transcript from an external device, by receiving the translated transcript from a user, and so forth. 
     The disclosed embodiment may further include analyzing the media stream to determine a voice profile for the individual, wherein the voice profile includes characteristics of the particular voice, or obtaining voice profile for the individual in a different way. For example, voice profile for the individual may be received using step  442 .

Consistent with the present disclosure, the virtual entity may be generated for revoicing the media stream. In one embodiment, the virtual entity may be deleted after the media stream is revoiced. Alternatively, the virtual entity may be stored for future dubbing of other media streams. The term “virtual entity” may refer to any type computer-generated entity that can be used for audibly reading text such as the translated transcript. The virtual entity may be associated with a synthesized voice than may be determined based on the voice profile of an individual speaking in the original media stream. According to step  710 , the processing device may determine a synthesized voice for a virtual entity intended to dub the individual, wherein the synthesized voice has characteristics identical to the characteristics of the particular voice. The disclosed embodiment may further include generating a revoiced media stream in which the translated transcript in the target language is spoken by the virtual entity. Consistent with the present disclosure, the term “an individual [that] speaks the target language” as used below with reference to the revoiced media stream means that a virtual entity with synthesized voice that has one or more characteristics identical to the voice characteristics of the individual in the original media stream is used to say the transcript translated to the target language. In one embodiment, the synthesized voice may sound substantially identical to the particular voice, such that when the virtual entity utters the original transcript in the origin language, the result is indistinguishable from the audio of the original media stream to a human ear. In another embodiment, the synthesized voice may sound similar to but distinguishable from the particular voice, for example, the virtual entity may sound like a young girl with French accent or an elderly man with a croaky voice. According to step  712 , the processing device may generate a revoiced media stream in which the translated transcript in the target language is spoken by the virtual entity. For example, steps  710  and  712  may use steps  444  and/or  446  to determine the synthesized voice and generate the revoiced media stream.

It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including a plurality of first individuals speaking in a primary language and at least one second individual speaking in a secondary language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  802 , the processing device may receive a media stream including a plurality of first individuals speaking in a primary language (e.g., English) and at least one second individual speaking in a secondary language (e.g., Russian). For example, step  802  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the received media stream associated with utterances in the first language and utterances in the second language. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  804 , the processing device may obtain a transcript of the received media stream associated with utterances in the first language and utterances in the second language. 
     The disclosed embodiment may further include determining that dubbing of the utterances in the primary language to a target language is needed and that dubbing of the utterances in the secondary language to the target language is unneeded. Consistent with the present disclosure, the processing device may identify cases where the dubbing of the utterances in the secondary language to the target language are needed and cases where the dubbing of the utterances in the secondary language to the target language are unneeded. In some examples, the identification of the cases may be based on the significant of the at least one second individual in the received media stream. For example, a main character or a supporting character. According to step 806, the processing device may determine that dubbing of the utterances in the primary language to a target language (e.g., French) is needed and that dubbing of the utterances in the secondary language to the target language is unneeded. For example, a machine learning model may be trained using training example to determine whether dubbing of utterances is need in different languages, and step 806 may use the trained machine learning model to analyze the transcript and determining whether dubbing is needed in the primary language and/or in the secondary language. An example of such training example may include a transcript, an indication of a particular utterance and an indication of a particular language, together with an indication of whether dubbing of the utterance is needed in the particular language. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to determine whether dubbing of utterances is need in different languages, and step 806 may use the artificial neural network to analyze the transcript and determining whether dubbing is needed in the primary language and/or in the secondary language. 
     The disclosed embodiment may further include analyzing the received media stream to determine a set of voice parameters for each of the plurality of first individuals. In one example, each set of voice parameters associated with each of the plurality of first individuals may be different in at least one voice parameter. According to step  818 , the processing device may analyze the received media stream to determine a set of voice parameters for each of the plurality of first individuals. The disclosed embodiment may further include determining a voice profile for each of the plurality of first individuals based on an associated set of voice parameters. As described above, voice profile determination module  406  may determine a voice profile for each one or more individuals speaking in the received media stream. According to step  810 , the processing device may determine a voice profile for each of the plurality of first individuals based on an associated set of voice parameters, or obtaining the voice profiles for the individuals in a different way. For example, voice profiles for the individuals may be received using step  442 . Some other non-limiting examples of voice profiles are described above, for example in relation to step  442 . 
     The disclosed embodiment may further include using the determined voice profiles and a translated version of the transcript to artificially generate a revoiced media stream in which the plurality of first individuals speak the target language and the at least one second individual speaks the secondary language. In one embodiment, revoicing unit  680  may use an artificial revoiced version (in the secondary language) of the utterances spoken by the at least one second individual to generate the revoiced media stream. Alternatively, revoicing unit  680  may use the original version of the utterances spoken by the at least one second individual to generate the revoiced media stream. According to step  812 , the processing device may use the determined voice profiles and a translated version of the transcript to artificially generate a revoiced media stream in which the plurality of first individuals speak the target language and the at least one second individual speaks the secondary language. For example, step  812  may use steps  444  and/or  446  to generate the revoiced media stream. 
     In one embodiment, the target language is the secondary language. For example, when revoicing a movie in English to Russian where the movie includes a specific character that speaks Russian, the specific character may not be revoiced. Consistent with the one embodiment, the revoiced media stream may be played to a user fluent in two or more languages. The disclosed embodiment may include determining to generate a revoiced media stream in which the at least one second individual speaks the secondary language (and not the target language) based on stored preferences of the user. The preferences of the user may be included in a user profile and stored in database  414 . For example, when the user is fluent in French and Russian, utterances in the primary language (e.g., English) may be dubbed into the target language (e.g., French) and utterances in the secondary language (e.g., Russian) may not be dubbed. 
     Disclosed embodiments may include identifying the first language spoken by the plurality of first individuals as a primary language of the received media stream and the second language spoken by the at least one second individual as a secondary language of the received media stream. The artificially generated revoiced media stream may take into account which language is the primary language and which language is the secondary language. For example, when most of the characters in the received media stream speak English and only one speaks Russian, the primary language would be English. Disclosed embodiments may include performing image analysis on the received media stream to determine that the at least one second individual said a certain utterance in the secondary language excluded from a dialogue with any of the plurality of the first individuals speaking the primary language. For example, media analysis unit  620  may distinguish between utterances included in a dialogue with one of plurality of first individuals speaking in the primary language and utterances excluded from a dialogue with any of the plurality of the first individuals. 
     Disclosed embodiments may include performing text analysis on the transcript to determine that the at least one second individual said a certain utterance in the secondary language excluded from a dialogue with any of the plurality of the first individuals speaking the primary language. For example, text analysis unit  635  may distinguish between utterances included in a dialogue with one of plurality of first individuals speaking in the primary language and utterances excluded from a dialogue with any of the plurality of the first individuals. Disclosed embodiments may include that the at least one second individual said a first utterance in the secondary language excluded from a dialogue with any of the plurality of the first individuals speaking the primary language, and artificially generating a revoiced media stream in which the first utterance is spoken in the secondary language. For example, the first utterance may be generated using voice generation unit  655  in the second language or included in its original version in the revoiced media stream. Disclosed embodiments may include determining that the at least one second individual said a second utterance in the secondary language included in a dialogue with one of the plurality of the first individuals speaking the primary language, and artificially generating a revoiced media stream in which the second utterance is spoken in the target language. For example, the second utterance may be generated using voice generation unit  655  in the target language. 
     Disclosed embodiments may include analyzing the received media stream to identify a third individual speaking in the secondary language, determining a voice profile of the third individual; and artificially generating a revoiced media stream in which the plurality of first individuals and the third individual speak in the target language and the at least one second individual speaks in the secondary language. For example, the third individual may be an important character in the media stream and the at least one second individual may be a supporting character. Disclosed embodiments may include identifying that the plurality of first individual speak the first language and that the at least one second individual speaks the second language. For example, audio analysis unit  510  or text analysis unit  525  may include instructions to determine which origin language is being used by each individual in the received media stream. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call or a recorded physical conversation) between the first individual and a user. Disclosed embodiments may reduce the value of the at least one second individual in the revoiced media stream compared to the dubbed voiced of a first individual. Disclosed embodiments may include identifying background chatter in the second language and avoid from determining voice profiles to individuals associated with the background chatter. 
       FIG.  8 B  is a schematic illustration depicting an implementation of method  900 . In the figure, original media stream  110  includes individual  113  that speaks in English (which is the primary language in media stream  110 ) and individual  116  that speaks in Spanish (which is the secondary language in media stream  110 . Consistent with disclosed embodiments, the system may artificially generate revoiced media stream  150  in which individual  113  speaks the target language (German) and individual  116  will continue to speak the secondary language. 
     3. Revoicing a Media Stream With Multiple Languages 
       FIG.  9 A  is a flowchart of an example method  900  for revoicing a media stream that includes individuals speaking in multiple origin languages, such that at least some of the individuals (e.g., all of the individuals) in the revoiced media stream will speak a single target language. Consistent with the present disclosure, method  900  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  900 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving an input media stream including a first individual speaking in a first language and a second individual speaking in a second language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  190 . According to step  902 , the processing device may receive an input media stream including a first individual speaking in a first language (e.g., English) and a second individual speaking in a second language (e.g., Russian). For example, step  902  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the input media stream associated with utterances in the first language and utterances in the second language. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  904 , the processing device may obtain a transcript of the input media stream associated with utterances in the first language and utterances in the second language. 
     The disclosed embodiment may further include analyzing the received media stream to determine a first set of voice parameters of the first individual and a second set of voice parameters of the second individual. The voice parameters may include various statistical characteristics of the first and second individuals such as average loudness or average pitch of the utterances in the first and second languages, spectral frequencies of the utterances in the first and second languages, variation in the loudness of the utterances in the first and second languages, the pitch of the utterances in the first and second languages, rhythm pattern of the utterances in the first and second languages, and the like. The voice parameters may also include specific characteristics of the first and second individuals such as specific utterances in the first and second languages pronounced in a certain manner. According to step  906 , the processing device may analyze the received media stream to determine a first set of voice parameters of the first individual and a second set of voice parameters of the second individual. 
     The disclosed embodiment may further include determining a first voice profile of the first individual based on the first set of voice parameters. As described above, voice profile determination module  406  may determine the voice profiles for each one or more individuals speaking in the received media stream. According to step  908 , the processing device may determine a first voice profile of the first individual based on the first set of voice parameters. Similarly, at step  910 , the processing device may determine a second voice profile of the second individual based on the second set of voice parameters. Additionally or alternatively, step  908  may obtain the first voice profile of the first individual in other ways, for example using step  442 . Additionally or alternatively, step  910  may obtain the first voice profile of the first individual in other ways, for example using step  442 . The disclosed embodiment may further include using the determined voice profiles and a translated version of the transcript to artificially generate a revoiced media stream in which both the first individual and the second individuals speak a target language. As described above, voice generation module  408  may generate artificial dubbed version of the received media stream. According to step  912 , the processing device may use the determined voice profiles and a translated version of the transcript to artificially generate a revoiced media stream in which both the first individual and the second individuals speak a target language (e.g., French). For example, step  912  may use steps  444  and/or  446  to generate the revoiced media stream. 
     In one embodiment, the target language is the first language. For example, a movie in English that a specific character that speaks Russian may be revoiced such that the specific character will also speak English. In another embodiment, the target language is a language other than the first and the second languages. For example, a movie in English that one character speaks Russian may be revoiced such that all the characters will speak French. 
     Disclosed embodiments may include identifying that the first individual speaks the first language and that the second individual speaks the second language. For example, audio analysis unit  510  or text analysis unit  525  may include instructions to determine which origin language is being used by each individual in the received media stream. Related embodiments may include identifying that the first individual speaks the first language during a first segment of the received media stream and the second language during a second segment of the received media stream. The processing device may generate a revoiced media stream in which the first individual speaks the target language during both the first segment of the received media stream and during the second segment of the received media stream. For example, when the first individual in a movie mainly speaks English but answers in Russian to the second individual’s questions, the answers in Russian (as well as the second individual’s questions) will also be revoiced into the target language. Related embodiments may include identifying that the first individual speaks the first language during a first segment of the received media stream and a language other than the second language during a second segment of the received media stream. The processing device may generate a revoiced media stream in which the first individual speaks the target language during the first segment of the received media stream and keeps the language other than the second language during a second segment of the received media stream. For example, when the first individual in a movie mainly speaks English but reads a text in Spanish, the text will not be revoiced into the target language, instead it will be kept in Spanish. 
     Disclosed embodiments may include identifying the first language spoken by the first individual as a primary language of the received media stream and the second language spoken by the second individual as a secondary language of the received media stream. The artificially generated revoiced media stream may take into account which language is the primary language and which language is the secondary language. For example, when most of the characters in the received media stream speak English and only one speaks Russian, the primary language would be English. Related embodiments may include purposely generating a revoiced media stream in which the second individual speaks the target language with an accent associated with the secondary language. With reference to the example above, the one character that speaks Russian may be revoiced such that the character will speak the target language in a Russian accent. Related embodiments may include purposely generating a revoiced media stream in which the second individual speaks at least one word in the secondary language and most of the words in the target language. For example, words such as “Hello,” “Thank you,” “Goodbye,” and more may be spoken in the original secondary language and not be translated and dubbed into the target language. 
     Disclosed embodiments may include determining the transcript from the received media stream. For example, as discussed above, transcript processing module  404  may determine the transcript of the received media stream using any suitable voice-to-text algorithm. Disclosed embodiments may include determining the transcript from the received media stream. For example, as discussed above, transcript processing module  404  may include instructions to translate the transcript of the received media stream to the target language using any suitable translation algorithm. Disclosed embodiments may include playing the revoiced media stream to a user and wherein determining the target language may be based on stored preferences of the user. The preferences of the user may be included in a user profile and stored in database  414 . Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call or a recorded physical conversation) between the first individual, the second individual, and a user. Disclosed embodiments may include improving the first voice profile and the second voice profile during the real-time conversation and changing a dubbed voice of the first individual and the second individual as the real-time conversation progress. For example, in the beginning of the real-time conversation the voice of the first individual may sound as a generic young woman and later in the conversation the voice of the first individual may sounds as if the first individual speaks the target language. 
       FIG.  9 B  is a schematic illustration depicting an implementation of method  900 . In the figure, original media stream  110  includes individual  113  that speaks in English (which is the primary language in media stream  110 ) and individual  116  that speaks in Spanish (which is the secondary language in media stream  110 ). Consistent with disclosed embodiments, the system may artificially generate revoiced media stream  150  in which both individual  113  and individual  116  speak the target language (German). 
     4. Artificially Generating an Accent Sensitive Revoiced Media Stream 
       FIG.  10 A  is a flowchart of an example method  1000  for revoicing a media stream that includes an individual speaking a first language with an accent in a second language, such that the individual will speak the target language in the revoiced media stream with a desired amount of accent in a second language. Consistent with the present disclosure, method  1000  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  1000 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including an individual speaking in a first language with an accent in a second language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  1002 , the processing device may receive a media stream including an individual speaking in a first language (e.g., English) with an accent in a second language (e.g., Russian). For example, step  1002  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the received media stream associated with utterances in the first language. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  1004 , the processing device may obtain a transcript of the received media stream associated with utterances in the first language. 
     The disclosed embodiment may further include analyzing the received media stream to determine a set of voice parameters of the individual. In one example, the set of voice parameters may include a level of accent in the second language. According to step  1006 , the processing device may analyze the received media stream to determine a set of voice parameters of the individual. Some non-limiting examples of such analysis are described herein, for example in relation to step  442 . The disclosed embodiment may further include determining a voice profile of the individual based on the set of voice parameters. As described above, voice profile determination module  406  may determine the voice profile for the individual. The voice profile may identify specific utterances in the first language that are pronounced with accent in the second language and other utterances in the first language that are not pronounced with accent in the second language. Some other non-limiting examples of voice profiles are described above, for example in relation to step  442 . According to step  1008 , the processing device may determine a voice profile of the individual based on the set of voice parameters, or obtaining voice profile for the individual in a different way. For example, step  1008  may receive a voice profile for the individual using step  442 . 
     The disclosed embodiment may further include accessing one or more databases to determine at least one factor indicative of a desired level of accent to introduce in a dubbed version of the received media stream. The one or more databases may include data structure  126 , data structure  136 , database  360 , or database  400 . The at least one factor may be specific to the target language, to the second language, to the user, to the individual, etc. According to step  1010 , the processing device may access one or more databases to determine at least one factor indicative of a desired level of accent to introduce in a dubbed version of the received media stream. In another example, at least one factor indicative of a desired level of accent to introduce in a dubbed version of the received media stream may be determined based on an analysis of the media stream received using step  1002 , may be determined based on user input, may be read from memory, and so forth. 
     The disclosed embodiment may further include using the determined voice profile, the at least one factor, and a translated version of the transcript to artificially generate a revoiced media stream in which the individual speaks the target language with an accent in the second language at the desired level. In one case, the revoiced media stream may include the individual speaking the target language without accent. In other case, the revoiced media stream may include the individual speaking the target language with an accent in the second language. According to step  1012 , the processing device may use the determined voice profile, the at least one factor, and a translated version of the transcript to artificially generate a revoiced media stream in which the individual speaks the target language with an accent in the second language at the desired level. In one example, step  1012  may use step  444  and/or step  446  to artificially generate the revoiced media stream. In another example, a machine learning model may be trained using training examples to generate media streams from voice profiles, factors indicative of desired levels of accent, and transcript, and step  1012  may use the trained machine learning model to generate the revoiced media stream from the determined voice profile, the at least one factor, and a translated version of the transcript. An example of such training example may include a voice profile, a factor, and a transcript, together with the desired media stream to be generated. 
     In one embodiment, the target language is a language other than the second language. For example, when revoicing a movie in English to French where the movie includes a specific character that speaks English with a Russian accent, the specific character may be revoiced to speak French with a Russian accent. In some cases, the processing device may artificially generate the revoiced media stream such that the individual would speak the target language without an accent associated with the second language. For example, when the at least one factor indicate that the desired level of accent is no accent. Disclosed embodiments may include determining a level of the accent associated with second language that the individual has in the received media stream, and artificially generating the revoiced media stream such that the individual would speak the target language with an accent in the second language at the determined level of accent. For example, the determined level of accent may be on a scale of zero to ten where “ten” is a heavy accent and “zero” is no accent. 
     Related embodiments may include determining that, in the received media stream, the individual used an accent associated with the second language for satiric purposes; and maintaining a similar level of accent in the artificially generated revoiced media stream. For example, in some cases characters in a movie use fake accent, the processing device will maintain the fake accent when dubbing the media stream to the target language. Alternatively, when accent associated with the second language for satiric purposes is identified the processing device may determine to remove it from the revoiced media stream. In related embodiments, the level of the accent in the second language that the individual has in the received media stream may be included in the determined voice profile and may be associated with specific utterances in the first language. For example, the voice profile may indicate that some words are pronounced with accent in the second language while other words are not pronounced with accent. 
     Consistent with the present disclosure, the revoiced media stream may be played to a user (e.g. user  170 ). Disclosed embodiments may include determining the at least one factor indicative of the desired level of accent to introduce in the revoiced media stream based on information associated with stored preferences of a user. The preferences of the user may be included in a user profile and stored in database  414 . Alternative embodiments may include determining the at least one factor indicative of the desired level of accent to introduce in the revoiced media stream based on information associated with system settings. For example, the system may have rules regarding which languages to dub with an accent and which languages to dub without an accent (even if the original voice in the received media stream had an accent). Example embodiments may include determining the at least one factor indicative of the desired level of accent to introduce in the revoiced media stream based on the second language. For example, the system may have a rule not to generate voice with Russian accent. 
     Other embodiments may include determining the at least one factor indicative of the desired level of accent to introduce in the revoiced media stream based on the target language. For example, the system may have a rule not to generate voice with any accent when dubbing the media stream to Chinese. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call or a recorded physical conversation) between the first individual and a user. In some cases, the target language may be the first language that the user understands (e.g., English). Disclosed embodiments may include identifying a first part of the conversation that the individual speaks the second language (e.g., French) and a second part of the conversation that the individual speaks the first language (e.g., English) with an accent associated with the second language. Related embodiments may include artificially generating the revoiced media stream such that the individual would speak in both the first part of the conversation and the second part of the conversation the target language (i.e., the first language) without an accent associated with the second language. 
       FIG.  10 B  is a schematic illustration depicting an implementation of method  1000 . In the figure, original media stream  110  includes individual  113  that speaks in English (without accent) and individual  116  that speaks in English with an accent (e.g., Russian accent). Consistent with disclosed embodiments, the system may artificially generate revoiced media stream  150  in which both individual  113  and individual  116  speak the target language (German), but individual  116  speaks in the target language with an accent as in the original media stream (e.g., also the Russian accent). 
     5. Automatically Revising a Transcript of a Media Stream 
       FIG.  11 A  is a flowchart of an example method  1100  for artificially generating a revoiced media stream in which a transcript of one the individuals speaking in the media stream is revised. Consistent with the present disclosure, method  1100  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  1100 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including a first individual and a second individual speaking in at least one language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  1102 , the processing device may receive a media stream including a first individual and a second individual speaking in at least one language. For example, step  1102  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the media stream including a first part associated with utterances spoke by the first individual and a second part associated with utterances spoke by the second individual. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  1104 , the processing device may obtain a transcript of the media stream including a first part associated with utterances spoke by the first individual and a second part associated with utterances spoke by the second individual. 
     The disclosed embodiment may further include analyzing the media stream to determine a voice profile of at least the first individual. In one example, the voice profile may be determined based on an identified set of voice parameters associated with the first individual. In another example, the voice profile may be determined using a machine learning algorithm without identifying the set of voice parameters. According to step  1106 , the processing device may analyze the media stream to determine a voice profile of at least the first individual. Additionally or alternatively, step  1106  may obtain the voice profile of the at least one individual in other ways, for example using step  442 . The disclosed embodiment may further include accessing at least one rule for revising transcripts of media streams. The at least one rule for revising transcripts of media streams may be stored in database  414 . One example of the rules may include automatically replacing vulgar or offensive words. According to step  1108 , the processing device may access at least one rule for revising transcripts of media streams. 
     The disclosed embodiment may further include according to the at least one rule, automatically revising the first part of the transcript and avoid from revising the second part of the transcript. As described above, transcript processing module  404  may revise the transcript, wherein revising the transcript may include translating the transcript, replacing words in the transcript while keeping the meaning of the sentences, updating the jargon of transcript, and more. According to step  1110 , according to the at least one rule, the processing device may automatically revise the first part of the transcript and avoid from revising the second part of the transcript. For example, step  1110  may use step  440  to revise the first part of the transcript. In one example, step  1110  may translate or transformed speech directly from the media stream received by step  1102 , for example as described above in relation to step  440 , and step  1104  may be excluded from method  1100 . Additionally or alternatively, step  1110  may receive such a revised segment of the transcript, for example by reading the revised segment of the transcript from memory, by receiving the revised segment of the transcript from an external device, by receiving the revised segment of the transcript from a user, and so forth. 
     The disclosed embodiment may further include using the determined voice profiles and the revised transcript to artificially generate a revoiced media stream in which the first individual speaks the revised first part of the transcript and the second individual speaks the second unrevised part of the transcript. In one case, the processing device may use the original voice of the second individual in the revoiced media stream. Alternatively, the processing device may use an artificially generated voice of the second individual. According to step  1112 , the processing device may use the determined voice profiles and the revised transcript to artificially generate a revoiced media stream in which the first individual speaks the revised first part of the transcript and the second individual speaks the second unrevised part of the transcript. For example, steps  1112  may use steps  444  and/or  446  to generate the revoiced media stream. 
     In one embodiment, both the first individual and the second individual speak a same language. Alternatively, the first individual speaks a first language and the second individual speaks a second language. Related embodiment includes artificially generating a revoiced media stream in which both the first individual and the second individual speak a target language. The target language may be the first language, the second language, or a different language. Disclosed embodiments may include determining that a revision of the first part of the transcript associated with the first individual is needed and that a revision of the second part of the transcript associated with the second individual is unneeded. In some cases, the determination which parts of the transmittal needs to be revised is based on identities of the first individual and the second individual. For example, the first individual may be a government official that should not said certain things and the second individual may be a reporter. In other cases, the determination which parts of the transmittal needs to be revised is based on the language spoken by the first individual and by the second individual. For example, when the first individual speaks a first language and the second individual speaks a second language, the processing device may determine to revise the part of the transcript associated with the first language. In one case, revising the first part of the transcript includes translating it to the second language. 
     In addition, the determination which parts of the transmittal needs to be revised is based on the utterances spoken by the first individual and the utterances spoken by the second individual the second individual. For example, the first individual uses vulgar or offensive words. Consistent with some embodiments, the at least one rule for revising transcripts is based on a detail about a user listing to the media stream. For example, the processing device may determine the age of the user based on information from the media player (e.g., communications device  160 ). Alternatively, the processing device may estimate the age of the user based on the hour the day. For example, revising the transcript in hours in which the media stream is more likely to be viewed by young users. The detail about the user may also gender, ethnicity, and more. Disclosed embodiments may include revising the first part of the transcript includes automatically replacing predefined words. For example the phrase “Aw, shit!” may be replace with the “Aw, shoot!,” the phrase “damn it” may be replace with “darn it,” and so on. 
     Additionally, revising the first part of the transcript may be based on a jargon associated with a time period. For example, remake the audio of an old movie to match the current jargon. In a specific case, the media stream is a song and disclosed embodiments may include artificially generating a revoiced song in which the first individual sings the revised first part of the transcript and the second individual sings the second unrevised part of the transcript. According to some embodiments, the processing device may use the original voice of the second individual in the revoiced media stream or an artificially generated voice of the second individual. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call or a recorded physical conversation) between the first individual and the second individual. In some cases, the first individual speaks a first language (e.g., French) or a first dialect of a language (Scottish English) and the second individual speaks a second language (e.g., English) or a second dialect of the language (American English). In these cases, revising the first part of the transcript may include translating the first part from the first language to the second language. In some cases, both the first individual and the second individual speak a same language (e.g., English). In these cases, revising the first part of the transcript may include changing or deleting certain utterances spoke by the first individual. For example, deleting sounds that the first individual made to clears his/her throat before talking. 
       FIG.  11 B  is a schematic illustration depicting an implementation of method  1100 . In the figure, original media stream  110  includes individual  113  and individual  116  that speak in English. Consistent with disclosed embodiments, the transcript of the individual  113  is revised due to the use of restricted words. In this case, the system may artificially generate revoiced media stream  150  in which the target language is the origin language (but obviously it can be any other language). In the revoiced media stream, individual  116  says the revised transcript. 
     6. Revising a Transcript of a Media Stream Based on User Category 
       FIG.  12 A  is a flowchart of an example method  1200  for artificially generating a revoiced media stream in which a transcript of one the individuals speaking in the media stream is revised based on a user category. Consistent with the present disclosure, method  1200  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  1200 , as described herein.

It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream destined to a particular user, wherein the media stream includes at least one individual speaking in at least one origin language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  1202 , the processing device may receive a media stream destined to a particular user, wherein the media stream includes at least one individual speaking in at least one origin language. For example, step  1202  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the media stream including utterances associated with the at least one individual. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  1204 , the processing device may obtain a transcript of the media stream including utterances associated with the at least one individual. 
     The disclosed embodiment may further include determining a user category indicative of a desired vocabulary for the particular user. The user category may be determined based on data about the particular user. In one example, the user category may be associated with the age of the particular user and the desired vocabulary is excluded of censored words. In another example, the user category may be based on a nationality of the particular user and the desired vocabulary includes different names for the same object. According to step  1206 , the processing device may determine a user category indicative of a desired vocabulary for the particular user. For example, the user category may be read from memory, received from an external device, received from a user, and so forth. In another example, a machine learning model may be trained using training examples to determine user categories for users from user information, and step  1206  may use the trained machine learning model to analyze user information of the particular user and determine the user category indicative of the desired vocabulary for the particular user. An example of such training example may include user information corresponding to a user, together with a user category for the user. Some non-limiting examples of such user information may include images of the user, voice recordings of the user, demographic information of the user, information based on past behavior of the user, and so forth. For example, the user information may be obtained using step  436 , may be read from memory, may be received from an external device, may be received from a user (the same user or a different user), and so forth. In yet another example, an artificial neural network (such as a deep neural network) may be configured to determine user categories for users from user information, and step  1206  may use the artificial neural network to analyze user information of the particular user and determine the user category indicative of the desired vocabulary for the particular user. 
     The disclosed embodiment may further include revising the transcript of the media stream based on the determined user category. As described above, transcript processing module  404  may revise the transcript, wherein revising the transcript may include translating the transcript, replacing words in the transcript while keeping the meaning of the sentences, updating the jargon of transcript, and more. According to step  1208 , the processing device may revise the transcript of the media stream based on the determined user category. For example, step  1208  may use step  440  to revise the transcript of the media stream. In another example, step  1208  may use an NLP algorithm to revise the transcript of the media stream. In yet another example, a machine learning model may be trained using training example to revise transcripts based on user categories, and the trained machine learning model may be used to analyze and revise the transcript of the media stream based on the determined user category. An example of such training example may include an original transcript and a user category, together with a desired revision of the transcript for that user category. In yet another example, an artificial neural network (such as recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to revise transcripts based on user categories, and the artificial neural network may be used to analyze and revise the transcript of the media stream based on the determined user category. In one example, step  1208  may translate or transformed speech directly from the media stream received by step  1202 , for example as described above in relation to step  440 . Additionally or alternatively, step  1208  may receive such revised transcript, for example by reading the revised transcript from memory, by receiving the revised transcript from an external device, by receiving the revised transcript from a user, and so forth. For example, step  1208  may select a revised transcript from a plurality of alternative revised transcripts based on the determined user category. 
     The disclosed embodiment may further include analyzing the media stream to determine at least one voice profile for the at least one individual. In one example, the voice profile may be determined based on an identified set of voice parameters associated with at least one individual. In another example, the voice profile may be determined using a machine learning algorithm without identifying the set of voice parameters. According to step  1210 , the processing device may analyze the media stream to determine at least one voice profile for the at least one individual. Additionally or alternatively, step  1210  may obtain the voice profile for the individual in other ways, for example using step  442 . The disclosed embodiment may further include using the determined at least one voice profile and the revised transcript to artificially generate a revoiced media stream in which the at least one individual speaks the revised transcript in a target language. The target language may be the origin language or a different language. In some cases, the processing device may revoice only the revised parts of the transcript. Alternatively, the processing device may revoice all the parts of the transcript associated with the at least one individual. According to step  1212 , the processing device may use the determined at least one voice profile and the revised transcript to artificially generate a revoiced media stream in which the at least one individual speaks the revised transcript in a target language. For example, steps  1212  may use steps  444  and/or  446  to determine the synthesized voice and generate the revoiced media stream. 
     In some embodiments, the media stream may include a plurality of individuals speaking a single origin language and the target language is the origin language. Alternatively, the media stream may include a plurality of individuals speaking a single origin language and the target language is a language other than the origin language. In some embodiments, the media stream may include a plurality of individuals speaking a two or more origin languages and the target language is one of the two or more origin languages. Alternatively, the media stream may include a plurality of individuals speaking a two or more origin languages and the target language is a language other than the two or more origin languages. 
     In disclosed embodiments, revising the transcript of the media stream based on the determined user category may include translating the transcript of the media stream according to rules associated the user category. Additional embodiments include determining the user category based on an age of the particular user, wherein the desired vocabulary is associated with censored words. Additional embodiments include determining the user category based on a nationality of the particular user, wherein the desired vocabulary is associated with different words. For example, in British English the front of a car is called “the bonnet,” while in American English, the front of the car is called “the hood.” Additional embodiments include determining the user category based on a culture of the particular user, wherein the desired vocabulary is associated with different words. For example, in the western countries someone may be called a cow, which usually means that he/she is fat. In eastern countries such as India, the word cow would not be used as an offensive word. Additional embodiments include determining the user category based on at least one detail about the particular user, wherein the desired vocabulary is associated with brand names more likely to be familiarized by the particular user. 
     Disclosed embodiment may include receiving data from a player device (e.g., communications device  160 ) associated with the particular user, and determining the user category based on the received data. The data may be provided to the processing device without intervention of the particular user. For example, the received data may include information about age, gender, nationality etc. Disclosed embodiment may include receiving input from the particular user and determining the user category based on the received input. The input may be indicative of user preferences. For example, a user in U.S. may prefer to listen to media stream in British English. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call or a recorded physical conversation) between the at least one individual and the particular user. In some cases, the origin language (e.g., French) and the target language is a language other than the origin language (e.g., Spanish). In these cases, the processing device may obtain information indicative of a gender of the particular user and determine the user category based on the gender of the particular user. Thereafter, the processing device may translate the transcript in a manner that takes into account the gender of the particular user.

For example, step  1306  may read the indication from memory, may receive the indication from an external device, may receive the indication from a user, may determine the indication based on a user category (for example, based on a user category determined by step  1206 ), and so forth. 
     The disclosed embodiment may further include translating the transcript of the media stream to the target language based on the preferred language characteristics. As mentioned above, transcript processing module  404  may include instructions to translate the transcript of the received media stream to the target language using any suitable translation algorithm. Transcript processing module  404  may receive as an input the indication about preferred language characteristics to translate the transcript of the media stream accordingly. According to step  1308 , the processing device may translate the transcript of the media stream to the target language based on the preferred language characteristics. For example, step  1308  may use step  440  to translate or otherwise transform the transcript. In one example, step  1308  may translate or transformed speech directly from the media stream received by step  1302 , for example as described above in relation to step  440 , and step  1304  may be excluded from method  1300 . Additionally or alternatively, step  1308  may receive such translated transcript, for example by reading the translated transcript from memory, by receiving the translated transcript from an external device, by receiving the translated transcript from a user, and so forth. For example, step  1308  may select a translated transcript of a plurality of alternative translated transcripts based on the preferred language characteristics. 
     The disclosed embodiment may further include analyzing the media stream to determine at least one voice profile for the at least one individual. In one example, the voice profile may be determined based on an identified set of voice parameters associated with at least one individual. In another example, the voice profile may be determined using a machine learning algorithm without identifying the set of voice parameters. According to step  1310 , the processing device may analyze the media stream to determine at least one voice profile for the at least one individual. Additionally or alternatively, step  1310  may obtain the voice profile for the at least one individual in other ways, for example using step  442 . 
     The disclosed embodiment may further include using the determined at least one voice profile and the translated transcript to artificially generate a revoiced media stream in which the at least one individual speaks the translated transcript in the target language. In some cases, the indication about the preferred language characteristics may also include details on preferred voice characteristics and voice generation module  408  take into consideration the user preferences when it artificially generates the revoiced media stream. According to step  1312 , the processing device may use the determined at least one voice profile and the translated transcript to artificially generate a revoiced media stream in which the at least one individual speaks the translated transcript in the target language. For example, steps  1312  may use steps  444  and/or  446  to determine the synthesized voice and generate the revoiced media stream. 
     Disclosed embodiment may include receiving the indication about the preferred language characteristics from a player device (e.g., communications device  160 ) associated with the particular user. The indication about the preferred language characteristics may be provided to the processing device without intervention of the particular user. For example, the indication about preferred language characteristics may include information about age, gender, nationality etc. Disclosed embodiment may include presenting to the particular user a plurality of options for personalizing the translation of the transcript, wherein the indication about the preferred language characteristics may be based on an input indicative of user selection. For example, a user in U.S. may prefer to listen to media stream in British English rather than American English and the transcript will be translated accordingly. In some embodiments, the preferred language characteristics may include language register, and the processing device is configured to translate the transcript of the media stream to the target language according to the preferred language register. For example, frozen register, formal register, consultative register, casual (informal) register, and intimate register. 
     In other embodiments, the preferred language characteristics may include style, and the processing device is configured to translate the transcript of the media stream to the target language according to the preferred style. For example, legalese, journalese, economese, archaism, and more. In other embodiments, the preferred language characteristics may include dialect, and the processing device is configured to translate the transcript of the media stream to the target language according to the preferred dialect. For example, a user in the U.S. may select that a media stream originally in German will be dubbed into English with one of the following dialects: Eastern New England, Boston Urban, Western New England, Hudson Valley, New York City, Inland Northern, San Francisco Urban, and Upper Midwestern. In other embodiments, the preferred language characteristics may include a level of slang, and the processing device is configured to translate the transcript of the media stream to the target language according to the preferred level of slang. 
     Consistent with the present disclosure, the indication about preferred language characteristics may further include details about preferred voice characteristics. In one embodiment, the processing device is configured to determine a preferred version of the at least one voice profile for the at least one individual; and use the preferred version of the at least one voice profile to artificially generate the revoiced media stream. In related embodiments, the details about the preferred voice characteristics may include at least one of: volume profile, type of accent, accent level, speech speed, and more. In one example, some users prefer that the individuals in the revoiced media stream will speak slower than in the original media stream. In another example, some users may prefer that the individuals in the revoiced media stream will speak with an accent associated with a specific dialect. In related embodiments, the details about the preferred voice characteristics may include a preferred gender. For example, when the original media stream is a podcast some user prefers to listen to a woman rather than a man. The processing device may use the determined voice profile (with all the changes in the intonations during the podcast) but replace the man voice with a woman voice. 
     In some embodiments, the media stream may include a plurality of individuals speaking a single origin language and the target language is a language other than the origin language. In other embodiments, the media stream may include a plurality of individuals speaking two or more origin languages and the target language is one of the two or more origin languages. In other embodiments, the media stream may include a plurality of individuals speaking a two or more origin languages and the target language is a language other than the two or more origin languages. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call or a recorded physical conversation) between the at least one individual and the particular user. In some embodiments, the processing device may obtain information indicative of language characteristics of the particular user (e.g., dialect, style, level of slang) and determine the preferred language characteristics based on the language characteristics of the particular user. Thereafter, the processing device may translate the transcript of the at least one individual in a manner similar to the language characteristics of the particular user. For example, if the user speaks with a certain style the dubbed version of the at least one individual will be artificially generated with a similar style. 
       FIG.  13 B  is a schematic illustration depicting an implementation of method  1300 . In the figure, original media stream  110  destined to a particular user  170  and includes individual  113  and individual  116  that speak in Spanish. Consistent with disclosed embodiments, the transcript of the original media stream is revised based on preferred language characteristics for the particular user. In this case, the system may artificially generate revoiced media stream  150  in which the target language is English and because user  170  prefers British English rather than American English, the word “apartamento” is translated to “flat” and not to “apartment.”

     9. Translating a Transcript of a Media Stream Based On Language Characteristics 
       FIG.  15 A  is a flowchart of an example method  1500  for artificially generating a revoiced media stream in which a transcript of at least one individual speaking in the media stream is translated based on language characteristics of the at least one individual. Consistent with the present disclosure, method  1500  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  1500 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including at least one individual speaking in at least one origin language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  1502 , the processing device may receive a media stream including at least one individual speaking in at least one language. For example, step  1502  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the media stream including utterances associated with the at least one individual. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  1504 , the processing device may obtain a transcript of the media stream including utterances associated with the at least one individual. 
     The disclosed embodiment may further include analyzing the transcript to determine a set of language characteristics for the least one individual. The determined set of language characteristics may include language register, style, dialect, level of slang, and more. The determination of the set of language characteristics may be executed by text analysis unit  525 . According to step  1506 , the processing device may analyze the transcript to determine a set of language characteristics for the least one individual. For example, a machine learning model may be trained using training examples to determine sets of language characteristics from transcripts, and step  1506  may use the trained machine learning model to analyze the transcript and determine the set of language characteristics for the at least one individual. An example of such training example may include a transcript, together with a set of language characteristics. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to determine sets of language characteristics from transcripts, and step  1506  may use the artificial neural network to analyze the transcript and determine the set of language characteristics for the at least one individual. 
     The disclosed embodiment may further include translating the transcript of the media stream to a target language based on the determined set of language characteristics. As mentioned above, transcript processing module  404  may include instructions to translate the transcript of the received media stream to the target language using any suitable translation algorithm. Transcript processing module  404  may receive as an input the determined set of language characteristics and translate the transcript of the media stream accordingly. According to step  1508 , the processing device may translate the transcript of the media stream to the target language based on the determined set of language characteristics. For example, step  1508  may use step  440  to translate or otherwise transform the transcript. Additionally or alternatively, step  1508  may receive such translated transcript, for example by reading the translated transcript from memory, by receiving the translated transcript from an external device, by receiving the translated transcript from a user, and so forth. For example, step  1508  may select a translated transcript of a plurality of alternative translated transcripts based on the determined set of language characteristics. 
     In one example, step  1506  may determine the set of language characteristics for the at least one individual directly from the media stream received by step  1502 . For example, a machine learning model may be trained using training examples to determine sets of language characteristics from media streams, and step  1506  may use the trained machine learning model to analyze the media stream received by step  1502  and determine the set of language characteristics for the at least one individual. An example of such training example may include a media stream, together with a set of language characteristics. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to determine sets of language characteristics from media streams, and step  1506  may use the artificial neural network to analyze the media stream received by step  1502  and determine the set of language characteristics for the at least one individual. In one example, step  1508  may translate or transformed speech directly from the media stream received by step  1502  (for example as described above in relation to step  440 ). In some examples, step  1504  may be excluded from method  1500 . 
     The disclosed embodiment may further include analyzing the media stream to determine at least one voice profile for the at least one individual. In one example, the voice profile may be determined based on an identified set of voice parameters associated with at least one individual. In another example, the voice profile may be determined using a machine learning algorithm without identifying the set of voice parameters. According to step  1510 , the processing device may analyze the media stream to determine at least one voice profile for the at least one individual. Additionally or alternatively, step  1510  may obtain the voice profile for the individual in other ways, for example using step  442 . 
     The disclosed embodiment may further include using the determined at least one voice profile and the translated transcript to artificially generate a revoiced media stream in which the at least one individual speaks the translated transcript in the target language. In some cases, the processing device may determine that a first individual in the media stream has a first set of language characteristics and a second individual in the media stream has a second set of language characteristics. Thereafter, the processing device may translate differently a same phrase said by the first individual and by the second individual. For example, the phrase “have a nice day” said by the first individual in English may be translated to “¡Que tú tengas un buen dia!” in informal Spanish. In contrast, the phrase “have a nice day” said by the second individual in English may be translated to “¡Que usted tenga un buen dia!” In formal Spanish. According to step  1512 , the processing device may use the determined at least one voice profile and the translated transcript to artificially generate a revoiced media stream in which the at least one individual speaks the translated transcript in the target language. For example, step  1512  may use steps  444  and/or  446  to determine the synthesized voice and generate the revoiced media stream. 
     In some embodiments, obtaining the transcript may include determining the transcript from the received media stream. For example, as discussed above, transcript processing module  404  may determine the transcript of the received media stream using any suitable voice-to-text algorithm. In related embodiments, determining the transcript from the received media stream may include determining metadata transcript information that include details on one or utterances of spoken by the at least one individual. In more related embodiments, determining the set of language characteristics for the least one individual may be based on the metadata transcript information. Disclosed embodiments may further include accessing stored information about the at least one individual and determining the set of language characteristics for the least one individual may be based on the stored information. For example, when translating a TV series the processing device may use transcripts of previous chapters to determine the set of language characteristics. 
     In some embodiments, the determined set of language characteristics may include language register, and the processing device is configured to translate the transcript of the media stream to the target language according to the determined language register of the at least one individual in the at least one origin language. For example, frozen register, formal register, consultative register, casual (informal) register, and intimate register. In other embodiments, the determined set of language characteristics may include style, and the processing device is configured to translate the transcript of the media stream to the target language according to the determined style of the at least one individual in the at least one origin language. For example, legalese, journalese, economese, archaism, and more. 
     In other embodiments, the determined set of language characteristics may include a level of slang, and the processing device is configured to translate the transcript of the media stream to the target language according to the determined level of slang of the at least one individual in the at least one origin language. In other embodiments, the determined set of language characteristics may include a gender of the at least one individual, and the processing device is configured to translate the transcript of the media stream to the target language according to the determined gender of the at least one individual. In some disclosed embodiments, determining the set of language characteristics for the least one individual may be further based on audio analysis of the media stream. For example, the tune of the at least one individual may affect on the determination of the language register of the at least one individual. 
     In some embodiments, the media stream may include a plurality of individuals speaking a single origin language and the target language is a language other than the origin language. In other embodiments, the media stream may include a plurality of individuals speaking a two or more origin languages and the target language is one of the two or more origin languages. In other embodiments, the media stream may include a plurality of individuals speaking two or more origin languages and the target language is a language other than the two or more origin languages. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call or a recorded physical conversation) between the at least one individual and the particular user. The processing device may initially translate the transcript of the at least one individual based on a default set of language characteristics, and after a period of time when the real-time conversation continue determine the set of language characteristics. In related embodiments, the processing device may determine that the changes between the default set of language characteristics and the determined set of language characteristics are less than a threshold and decide to keep using the default set of language characteristics. 
       FIG.  15 B  is a schematic illustration depicting an implementation of method  1500 . In the figure, original media stream  110  includes individual  113  and individual  116  that speak in English. Consistent with disclosed embodiments, the system may determine a set of language characteristics for individual  113  and individual  116  and translate the transcript of the media stream to a target language based on the determined set of language characteristics. In this case, the system may artificially generate revoiced media stream  150  in which individual  113  determined to speak in a formal register and individual  116  determined to speak in informal register. Therefore, the translation is different. 
     10. Providing Explanations in Revoiced Media Streams Based On Target Language 
       FIG.  16 A  is a flowchart of an example method  1600  for providing explanations in the revoiced media stream to something that was discussed in the original media stream the origin language but may not be familiar to users that speak the target language. Consistent with the present disclosure, method  1600  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  1600 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including at least one individual speaking in an origin language, wherein the media stream is associated with a transcript in the origin language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  1602 , the processing device may receive a media stream including at least one individual speaking in an origin language, wherein the media stream is associated with a transcript in the origin language. For example, step  1602  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining an indication that the media stream is to be revoiced to a target language. As described above, the indication may be received from a particular user or determined by a processing device of the suggested system. According to step  1604 , the processing device may obtain an indication that the media stream is to be revoiced to a target language. 
     The disclosed embodiment may further include analyzing the transcript to determine that the at least one individual in the received media stream discussed a subject likely to be unfamiliar with users associated with the target language. The subject likely to be unfamiliar with users associated with the target language may be a name of a local food common in counties speaking the origin language, but less common in countries that speak the target language, an event likely to be unfamiliar with users associated with the target language, a public figure likely to be unfamiliar with users associated with the target language, and more. For example, the public figure may be a politician well known in a country associated with the media stream, but less known in countries that speak the target language. According to step  1606 , the processing device may analyze the transcript to determine that the at least one individual in the received media stream discussed a subject likely to be unfamiliar with users associated with the target language. For example, a machine learning model may be trained using training examples to determine whether topics discussed in transcripts are likely to be unfamiliar with users, and step  1606  may use the trained machine learning model to analyze the transcript to determine that the at least one individual in the received media stream discussed a subject likely to be unfamiliar with users associated with the target language. An example of such training example may include a transcript and an indication of a target language, together with an indication of whether the topics discussed in the transcript are likely to be unfamiliar with users associated with the target language. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to determine whether topics discussed in transcripts are likely to be unfamiliar with users, and step  1606  may use the artificial neural network to analyze the transcript to determine that the at least one individual in the received media stream discussed a subject likely to be unfamiliar with users associated with the target language. 
     The disclosed embodiment may further include determining an explanation designed for users associated with the target language to the subject discussed by the at least one individual in the origin language. As mentioned above, the processing device may determine the explanation using information available in database  360  or database  365 . The explanation may be specific for the target language and may include cultural explanations. According to step  1608 , the processing device may determine an explanation designed for users associated with the target language to the subject discussed by the at least one individual in the origin language. For example, step  1608  may use step  1708  to determine the explanation. For example, a data structure may include explanations arranged by terms and/or topics, and step  1608  may obtain the explanation by accessing the data structure with a term and/or a topic corresponding to the subject identified as likely to be unfamiliar with users associated with the target language by step  1606 . In another example, an artificial neural network (such as a deep neural network, etc.) may be configured to determine explanations to subjects, and step  1608  may use the artificial neural network to obtain the explanation. Additionally or alternatively, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to alter transcripts by adding explanations designed for users associated with the target language, and step  1608  may use the artificial neural network to analyze the transcript and generate the explanations. 
     The disclosed embodiment may further include analyzing the media stream to determine at least one voice profile for the at least one individual. In one example, the voice profile may be determined based on an identified set of voice parameters associated with at least one individual. In another example, the voice profile may be determined using a machine learning algorithm without identifying the set of voice parameters. According to step  1610 , the processing device may analyze the media stream to determine at least one voice profile for the at least one individual. Additionally or alternatively, step  1610  may obtain the voice profile for the at least one individual in other ways, for example using step  442 . 
     The disclosed embodiment may further include using the determined at least one voice profile and a translated version of the transcript to artificially generate a revoiced media stream in which the at least one individual speaks in the target language, wherein the revoiced media stream provides the determined explanation to the subject discussed by the at least one individual in the origin language. In some cases, the explanation to the subject discussed by the at least one individual in the origin language may be provided in a text message. Alternatively, the explanation to the subject discussed by the at least one individual in the origin language may be included in the translated transcript and be audibly provided using the voice of the at least one individual. According to step  1612 , the processing device may use the determined at least one voice profile and a translated version of the transcript to artificially generate a revoiced media stream in which the at least one individual speaks in the target language, wherein the revoiced media stream provides the determined explanation to the subject discussed by the at least one individual in the origin language. For example, steps  1612  may use steps  444  and/or  446  to determine the synthesized voice and generate the revoiced media stream. 
     Disclosed embodiments may include receiving the indication that the media stream is to be revoiced to a target language from a player device (e.g., communications device  160 ) associated with a particular user that the media stream is destined to. The indication may be provided to the processing device without intervention of the particular user. For example, the indication may include information about the language of the operating software of the player device. Disclosed embodiments may include receiving the indication that the media stream is to be revoiced to a target language from an owner of the media stream (e.g., media owner  120 ). For example, a media owner wishes to have the media stream available in a target language. Disclosed embodiments may include determining that that the media stream is to be revoiced to the target language based on information about a particular user that the media stream is destined to, wherein the indication is based on the determination. Disclosed embodiments include determining that the at least one individual in the received media stream discussed about an object likely to be unfamiliar with users associated with the target language. For example, the object may be a name of a local food common in counties speaking the origin language, but less common in countries that speak the target language. 
     Disclosed embodiments include determining that the at least one individual in the received media stream discussed about an event likely to be unfamiliar with users associated with the target language. For example, the event may be a historic event well known in a country associated with the media stream, but less known in countries that speak the target language.

Disclosed embodiments include determining that at least one individual in the received media stream said a name of a person (or a place) that has meaning in the origin language. For example, the names “Luke Skywalker” and “Han Solo” convey information that users should know about the characters. The processing device may provide an explanation about the meaning of the name to users that speak the target language. In some embodiments, the determination that the at least one individual in the received media stream discussed about a subject likely to be unfamiliar with a particular user that the media stream is destined to may be based on an age of the particular user. 
     In other embodiments, the determination that the at least one individual in the received media stream discussed about a subject likely to be unfamiliar with a particular user that the media stream is destined to may be based on a nationality of the particular user. Consistent with the present disclosure, if the media stream is an audio stream, the explanation may be included in the translated transcript and provided audibly. In some examples, the voice of the at least one individual speaking the target language may provide the explanation. Consistent with the present disclosure, if the media stream is a video stream, the explanation may be included in a text message. In some examples, the text message may be provided after receiving an input from the user that he/she is interested in getting the explanation. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call, a video conference, or a recorded physical conversation) between the at least one individual and a user. The media stream may be captured by a communication device of the user. In this embodiment, the processing device may provide the explanation via a pop-up text message on the display of the communication device.

According to step  1706 , the processing device may analyze the transcript to determine that the at least one individual in the received media stream discussed a subject likely to be unfamiliar with the particular user. In one example, step  1706  may determine that the at least one individual in the received media stream discussed a subject likely to be unfamiliar with the particular user based on the information about the particular user. In one example, a machine learning model may be trained using training examples to determine whether subjects are likely to be unfamiliar with users based on information about the users, and step  1706  may use the trained machine learning model to analyze the transcript and/or the media stream obtained by step  1702  to determine that the at least one individual in the received media stream discussed a subject likely to be unfamiliar with the particular user based on the information about the particular user. An example of such training example may include information about a user, a transcript and/or a media stream, and a label indicating whether the transcript and/or the media stream include a subject likely to be unfamiliar with the user. 
     The disclosed embodiment may further include determining an explanation designed for the particular user to the subject discussed by the at least one individual in the origin language. As mentioned above, the processing device may determine the explanation using information available in database  360  or database  365 . The explanation may be specific for the particular user and may include cultural explanations. According to step  1708 , the processing device may determine an explanation designed for the particular user to the subject discussed by the at least one individual in the origin language. For example, step  1708  may use step  1608  to determine the explanation. 
     The disclosed embodiment may further include analyzing the media stream to determine at least one voice profile for the at least one individual. In one example, the voice profile may be determined based on an identified set of voice parameters associated with at least one individual. In another example, the voice profile may be determined using a machine learning algorithm without identifying the set of voice parameters. According to step  1710 , the processing device may analyze the media stream to determine at least one voice profile for the at least one individual. Additionally or alternatively, step  1718  may obtain the voice profile for the individual in other ways, for example using step  442 . 
     The disclosed embodiment may further include using the determined at least one voice profile and a translated version of the transcript to artificially generate a revoiced media stream for the particular user in which the at least one individual speaks in the target language, wherein the revoiced media stream provides the determined explanation to the subject discussed by the at least one individual in the origin language. In some cases, the explanation to the subject discussed by the at least one individual in the origin language may be provided in a text message. Alternatively, the explanation to the subject discussed by the at least one individual in the origin language may be included in the translated transcript and be audibly provided using the voice of the at least one individual. According to step  1712 , the processing device may use the determined at least one voice profile and a translated version of the transcript to artificially generate a revoiced media stream for the particular user in which the at least one individual speaks in the target language, wherein the revoiced media stream provides the determined explanation to the subject discussed by the at least one individual in the origin language. For example, step  1712  may use steps  444  and/or  446  to determine the synthesized voice and generate the revoiced media stream. 
     Disclosed embodiments may include receiving the information about the particular user from a player device (e.g., communications device  160 ) associated with a particular user that the media stream is destined to. The information may be provided to the processing device without intervention of the particular user. For example, the indication may include information about the language of the operating software of the player device. Disclosed embodiments may include receiving the information about the particular user from a server storing profiles of a plurality of users (e.g., server  133 ). In other disclosed embodiments, the determination that the particular user is unlikely to be familiarized with the subject discussed by the at least one individual in the media stream is based on the information about the particular user. Specifically, in one embodiment, the determination that the particular user is unlikely to be familiarized with the subject discussed by the at least one individual in the media stream to may be based on an age of the particular user. 
     In addition, the determination that the particular user is unlikely to be familiarized with the subject discussed by the at least one individual in the media stream to may be based on a nationality of the particular user. In addition, the determination that the particular user is unlikely to be familiarized with the subject discussed by the at least one individual in the media stream to may be based on a technical background of the particular user. Disclosed embodiments include determining that the particular user is unlikely to be familiarized with an object discussed by the at least one individual in the media stream. For example, the object may be a name of a local food common in counties speaking the origin language, but less common in countries that speak the target language. Disclosed embodiments include determining that the particular user is unlikely to be familiarized with an event discussed by the at least one individual in the media stream. For example, the event may be a historic event well known in a country associated with the media stream, but less known in countries that speak the target language. Disclosed embodiments include determining that the particular user is unlikely to be familiarized with a public figure discussed by the at least one individual in the media stream. For example, the public figure may be a politician well known in a country associated with the media stream, but less known in countries that speak the target language. 
     Disclosed embodiments include determining that at least one individual in the received media stream said a name of a person (or a place) that has meaning in the origin language. For example, the names “Luke Skywalker” and “Han Solo” convey information that users should know about the characters. The processing device may provide an explanation about the meaning of the name to users that speak the target language. Consistent with the present disclosure, if the media stream is an audio stream, the explanation may be included in the translated transcript and provided audibly. In some examples, the voice of the at least one individual speaking the target language may provide the explanation. Consistent with the present disclosure, if the media stream is a video stream, the explanation may be included in a text message. In some examples, the text message may be provided after receiving an input from the user that he/she is interested in getting the explanation. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call, a video conference, or a recorded physical conversation) between the at least one individual and the particular user. The media stream may be captured by a communication device of the user. In this embodiment, the processing device may provide the explanation via a pop-up text message on the display of the communication device associated with the particular user. 
       FIG.  17 B  is a schematic illustration depicting an implementation of method  1700 . In the figure, original media stream  110  destined to user  170  and includes individual  113  and individual  116  that speak in English. Consistent with disclosed embodiments, the system may determine individual in the received media stream discussed a subject likely to be unfamiliar with user  170  and cause an explanation to the subject to be provided in the target language. In this case, the system may artificially generate revoiced media stream  150  for a particular user under 6 years old unlikely to know who Winston Churchill is. Accordingly, the revoiced media stream includes and explanation in form of a message in Spanish. 
     12. Renaming Characters in Revoiced Media Streams 
       FIG.  18 A  is a flowchart of an example method  1800  for renaming characters in revoiced media streams upon determining that the name in the target language may cause antagonism. Consistent with the present disclosure, method  1800  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  1800 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including a plurality of individuals speaking in an origin language, wherein the media stream is associated with a transcript in the origin language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  180 . According to step  1802 , the processing device may receive a media stream including a plurality of individuals speaking in an origin language, wherein the media stream is associated with a transcript in the origin language. For example, step  1802  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining an indication that the media stream is to be revoiced to a target language. As described above, the indication may be received from a particular user or determined by a processing device of the suggested system. According to step  1804 , the processing device may obtain an indication that the media stream is to be revoiced to a target language. 
     The disclosed embodiment may further include analyzing the transcript to determine that an original name of a character in the received media stream is likely to cause antagonism with users that speak the target language. The name of the character in the received media stream may cause antagonism with users that speak the target language when the name is difficult to pronounce, when the name resembles to a name that has religious significant in the target language, when the name resembles to a name that has historical significant in the target language, when the name resembles to a name of a public figure, etc. According to step  1806 , the processing device may analyze the transcript to determine that an original name of a character in the received media stream is likely to cause antagonism with users that speak the target language. For example, step  1806  may access a list of names that likely to cause antagonism with users that speak the target language to determine whether the original name is likely to cause antagonism with users that speak the target language. 
     The disclosed embodiment may further include translating the transcript to the target language using a substitute name for the character. As mentioned above, the translation may be implemented by transcript processing module  404 . According to step  1808 , the processing device may translate the transcript to the target language using a substitute name for the character. For example, step  1808  may use step  440  to translate or otherwise transform the transcript. In one example, step  1808  may translate or transformed speech directly from the media stream received by step  1802 , for example as described above in relation to step  440 . 
     The disclosed embodiment may further include analyzing the media stream to determine a voice profile for each of the plurality of individuals. In one example, the voice profile may be determined based on a separate set of voice parameters associated with each individual. In another example, the voice profile may be determined using a machine learning algorithm without identifying the set of voice parameters. The voice profile may describe the changes of the voice of the individual during the whole media stream. According to step  1810 , the processing device may analyze the media stream to determine a voice profile for each of the plurality of individuals. Additionally or alternatively, step  1810  may obtain the voice profile for each of the plurality of individuals in other ways, for example using step  442 . 
     The disclosed embodiment may further include using the determined voice profiles and the translated transcript to artificially generate a revoiced media stream in which the plurality of individuals speak in the target language and the character is named the substitute name. In some cases, processing device may determine to forego renaming the character. The processing device may evaluate the benefits of renaming (e.g., evaluating the risk of cause antagonism) compare to the risk of damaging the viewing experience. According to step  1812 , the processing device may use the determined voice profiles and the translated transcript to artificially generate a revoiced media stream in which the plurality of individuals speak in the target language and the character is named the substitute name. For example, step  1812  may use steps  444  and/or  446  to generate the revoiced media stream. 
     In some embodiments, the determination that the name of the character is likely to cause antagonism with users that speak the target language, is because the original name of the character will be difficult to pronounce by users that speak the target language. Related embodiments may include determining a substitute name that will be easier to pronounce than the original name. For example, assuming the original media stream has a character named Milla Jovovich. When the media stream is revoiced to Japanese, the processing device may determine that the name is too hard to pronounce by user speaking Japanese and select a different name. In some embodiments, the determination that the name of the character is likely to cause antagonism with users that speak the target language, is because the original name of the character resembles a name that has religious significant to users that speak the target language. Related embodiments may include determining a substitute name that will be less resembled to the name that has religious significant in the target language. For example, assuming the original media stream has a cat named Mahmud. When revoicing the media stream to Arabic, the processing device may determine that the name is too resemble to the name of Muhammad and decide to call the cat Kamilah. 
     In some embodiments, the determination that the name of the character is likely to cause antagonism with users that speak the target language, is because the original name of the character resembles a name that has historic significant to users that speak the target language. Related embodiments may include determining a substitute name that will be less resemble to the name that has historic significant in the target language. For example, assuming the original media stream has a character named Wolf Hertal. When the media stream is revoiced to Hebrew, the processing device may determine that the name is too similar to Adolf Hitler and select a different name. In some embodiments, the determination that the name of the character is likely to cause antagonism with users that speak the target language, is because the original name of the character is similar to a name of a public figure in a country that speak the target language. Related embodiments may include determining a substitute name that will be other than the name of the public figure. 
     In one embodiment, the processing device may estimate an antagonism level associated with the name of the character and determine to rename the character when the antagonism level is greater than a first threshold. In a related one embodiment, the processing device may determine the importance level of keeping that the name of the charterer, and when the importance level is greater than a second threshold the processing device may decide to forego renaming the character. For example, when the name may convey a certain idea. In one embodiment, the processing device may determine to rename the character when the antagonism level is greater than the first threshold and the importance level is greater than the second threshold. In one embodiment, the processing device may determine to forego changing the name of the character when the antagonism level is greater than the first threshold and the importance level is greater than the second threshold. Disclosed embodiments include determining that the name of the character (or a place) that has meaning in the origin language. For example, the names “Luke Skywalker” and “Han Solo” convey information that users should know about the characters. The processing device may provide an explanation about the meaning of the name to users that speak the target language. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call, a video conference, or a recorded physical conversation) between the plurality of individual. The media stream may be captured by a communication device of one of the individuals. In this embodiment, the processing device may determine that this is a real-time conversion and decide to forego renaming the character. 
       FIG.  18 B  is a schematic illustration depicting an implementation of method  1800 . In the figure, original media stream  110  includes individual  113  and individual  116  that speak in English. Consistent with disclosed embodiments, the system may determine that an original name of a character in the received media stream is likely to cause antagonism with users that speak the target language and translate the transcript to the target language using a substitute name for the character. In this case, the name “Mahmud” in the original media stream was changed to “Kamilah” because it resembles to the name of Muhammad and this may offend users that speak Arabic. The system may artificially generate revoiced media stream  150  in which the substitute name is used. 
     13. Revoicing Media Stream With Rhymes 
       FIG.  19 A  is a flowchart of an example method  1900  for artificially generating a revoiced media stream in a manner that at least partially preserves the rhymes of the transcript in the origin language. Consistent with the present disclosure, method  1900  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  1900 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including at least one individual speaking in an origin language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  190 . According to step  1902 , the processing device may receive a media stream including at least one individual speaking in an origin language. For example, step  1902  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the media stream including utterances spoke in the origin language. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  1904 , the processing device may obtain a transcript of the media stream including utterances spoke in the origin language. 
     The disclosed embodiment may further include determining that the transcript includes a first utterance that rhymes with a second utterance. Consistent with the present disclosure, transcript processing module  404  may include machine learning models to identify rhymes. According to step  1906 , the processing device may determine that the transcript includes a first utterance that rhymes with a second utterance. For example, a machine learning model may be trained using training examples to determine whether pairs of utterances rhymes, and step  1906  may use the trained machine learning model to analyze the transcript and determine that the transcript includes a first utterance that rhymes with a second utterance. An example of such training example may include a pair of utterances, for example in textual format, together with a label indicating whether the pair of utterances rhymes. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to determine whether pairs of utterances rhymes, and step  1906  may use the artificial neural network to analyze the transcript and determine that the transcript includes a first utterance that rhymes with a second utterance. Additionally or alternatively, step  1906  may comprise determining that the media stream received by step  1902  includes a first utterance that rhymes with a second utterance. For example, a machine learning model may be trained using training examples to determine whether pairs of utterances rhymes, and step  1906  may use the trained machine learning model to analyze the media stream received by step  1902  and determine that the media stream includes a first utterance that rhymes with a second utterance. An example of such training example may include a pair of utterances, for example in an audio data, together with a label indicating whether the pair of utterances rhymes. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to determine whether pairs of utterances rhymes, and step  1906  may use the artificial neural network to analyze the media stream received by step  1902  and determine that the media stream includes a first utterance that rhymes with a second utterance. 
     The disclosed embodiment may further include translating the transcript of the media stream to a target language in a manner that at least partially preserves the rhymes of the transcript in the origin language. In one example, translating the transcript in a manner that at least partially preserves the rhymes of the transcript in the origin language may include translating the first sentence such that it ends with a first word in the target language, and translating the second sentence such that it ends with a second word in the target language, wherein the second word rhymes with the first word. According to step  1908 , the processing device may translate the transcript of the media stream to a target language in a manner that at least partially preserves the rhymes of the transcript in the origin language. For example, step  1908  may use step  440  to translate or otherwise transform the transcript. In one example, step  1908  may translate or transformed speech directly from the media stream received by step  1902 , for example as described above in relation to step  440   
     The disclosed embodiment may further include analyzing the media stream to determine at least one voice profile for the at least one individual. In one example, the voice profile may be determined using a machine learning algorithm and describes the changes of the voice of the individual during the whole media stream. According to step  1910 , the processing device may analyze the media stream to determine at least one voice profile for the at least one individual. Additionally or alternatively, step  1910  may obtain the voice profile for the individual in other ways, for example using step  442 . 
     The disclosed embodiment may further include using the determined at least one voice profile and the translated transcript to artificially generate a revoiced media stream in which the at least one individual speaks the translated transcript that includes rhymes in the target language. In some cases, processing device may artificially generate the revoiced media stream in a manner that at least partially preserves the rhymes of the transcript in the origin language. Specifically, the processing device may confirm that the translation of the first utterance is pronounced similarly to the translation of the second utterance. According to step  1912 , the processing device may use the determined at least one voice profile and the translated transcript to artificially generate a revoiced media stream in which the at least one individual speaks the translated transcript that includes rhymes in the target language. For example, steps  1912  may use steps  444  and/or  446  to generate the revoiced media stream. 
     Consistent with embodiments of the present disclosure, translating the transcript of the media stream in a manner that at least partially preserves the rhymes of the transcript in the origin language includes: identifying a first plurality of words in the target language that corresponds with the first utterance in the origin language; identifying a second plurality of words in the target language that corresponds with the second utterance in the origin language; select one of first plurality of words in the target language and one of the second plurality of words in the target language, wherein the selected words rhyme with each other. Related embodiments include artificially generating the revoiced media stream in a manner that at least partially preserves the rhymes of the transcript in the origin language. Specifically, the processing device may confirm that the selected word out of the first plurality of words is pronounced similarly to the selected word out of the second plurality of words. 
     In some embodiments, the selected word out of the first plurality of words is the default word for translating the first utterance, and the processing device is configured to select a word out of the second plurality of words that rhymes with the selected word out of the first plurality of words. Specifically, the selected word out of the second plurality of words is other than a default word for translating the second utterance. In alterative embodiments, the selected word out of the first plurality of words is other than a default word for translating the first utterance, and the selected word out of the second plurality of words is also other than a default word for translating the second utterance. In some embodiments, the first utterance includes one or more words in the original language, and the processing device is configured to select a set of words that that corresponds with the first utterance in the origin language. 
     Consistent with embodiments of the present disclosure, translating the transcript of the media stream in a manner that at least partially preserves the rhymes of the transcript in the origin language includes: determining a meaning of a first sentence that ends with the first utterance in the origin language; determining a meaning of second sentence that ends with the second utterance in the origin language; translating the first sentence such that it ends with a first word in the target language; translating the second sentence such that it ends with a second word in the target language, wherein the second word rhymes with the first word. Related embodiments include artificially generating the revoiced media stream in a manner that at least partially preserves the rhymes of the transcript in the origin language. Specifically, the processing device may confirm that the first word is pronounced similarly to the second word. 
     In some embodiments, the processing device is configured to identify cases when translation in a manner that preserves a meaning of the transcript is more important than translation in a manner that at least partially preserves the rhymes of the transcript in the origin language. In these cases, the processing device may forego translating the transcript in a manner that at least partially preserves the rhymes of the transcript in the origin language. For example, when revoicing news. In some embodiments, the processing device is configured to identify cases when translation in a manner that preserves a meaning of the transcript is less important than translation in a manner that at least partially preserves the rhymes of the transcript in the origin language. In these cases, the processing device may translate the transcript in a manner that at least partially preserves the rhymes of the transcript in the origin language even when a quality of the translation damages. For example, when revoicing a kids show. Embodiments of the present disclosure include attempting to find a perfect rhyme for the translation of the first utterance and the second utterance. Upon, a failure to find a perfect rhyme, the processing device is configured to attempt to find a family rhyme. Upon, a failure to find a perfect rhyme, the processing device is configured to attempt to find a consonance rhyme. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call, a video conference, or a recorded physical conversation) between the plurality of individual. The media stream may be captured by a communication device of one of the individuals. In this embodiment, the processing device may determine that this is a real-time conversion and decide to forego translating the transcript in a manner that at least partially preserves the rhymes of the transcript in the origin language. 
       FIG.  19 B  is a schematic illustration depicting an implementation of method  1900 . In the figure, original media stream  110  includes individual  113  and individual  116  that speak in English. Consistent with disclosed embodiments, the system may determine that the transcript includes a first utterance that rhymes with a second utterance (e.g., “cat” and “hat”). The system may translate the transcript of the media stream to a target language in a manner that at least partially preserves the rhymes of the transcript in the origin language. For example, the system may translate “the cat in the hat” to “le chat chapeauté” rather than “le chat dans le chapeau” because the first version at least partially preserves the rhymes of the transcript in the origin language. The system may artificially generate revoiced media stream  150  in which the accuracy of the translation is damaged in order to at least partially preserves the rhymes of the transcript in the origin language. 
     14. Maintaining Original Volume Changes of a Character In Revoiced Media Stream 
       FIG.  20 A  is a flowchart of an example method  2000  for artificially generating a revoiced media stream in which a ratio of the volume levels between translated utterances in the revoiced media stream is substantially identical to a ratio of volume levels between original utterances in the received media stream. Consistent with the present disclosure, method  2000  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  2000 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including an individual speaking in an origin language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  2002 , the processing device may receive a media stream including an individual speaking in an origin language. For example, step  2002  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the media stream including a first utterance and a second utterance spoke in the original language. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  2004 , the processing device may obtain a transcript of the media stream including a first utterance and a second utterance spoke in the original language. 
     The disclosed embodiment may further include translating the transcript of the media stream to a target language, wherein the translated transcript includes a first set of words in the target language that corresponds with the first utterance and a second set of words in the target language that corresponds with the second utterance. As mentioned above, transcript processing module  404  may include instructions to translate the transcript of the received media stream to the target language using any suitable translation algorithm. Transcript processing module  404  may receive as an input the indication about language characteristics to translate the transcript of the media stream accordingly. According to step  2006 , the processing device may translate the transcript of the media stream to a target language, wherein the translated transcript includes a first set of words in the target language that corresponds with the first utterance and a second set of words in the target language that corresponds with the second utterance. For example, step  2006  may use step  440  to translate or otherwise transform the transcript. In one example, step  2006  may translate or transformed speech directly from the media stream received by step  2002 , for example as described above in relation to step  440 . Additionally or alternatively, step  2006  may receive such translated transcript, for example by reading the translated transcript from memory, by receiving the translated transcript from an external device, by receiving the translated transcript from a user, and so forth. 
     The disclosed embodiment may further include analyzing the media stream to determine a voice profile for the individual, wherein the voice profile is indicative of a ratio of volume levels between the first and second utterances as they were spoken in the media stream. In other embodiments, the voice profile may be indicative of: intonation differences between the first and second utterances, pitch differences between the first and second utterances, accent differences between the first and second utterances. According to step  2008 , the processing device may analyze the media stream to determine a voice profile for the individual, wherein the voice profile is indicative of a ratio of volume levels between the first and second utterances as they were spoken in the media stream. Additionally or alternatively, step  2008  may obtain the voice profile for the individual in other ways, for example using step  442 . 
     The disclosed embodiment may further include determining metadata information for the translated transcript, wherein the metadata information includes desired volume levels for each of the first and second sets of words that correspond with the first and second utterances. The metadata information may include the desired level of intonation, pitch, accent, and more. According to step  2010 , the processing device may determine metadata information for the translated transcript, wherein the metadata information includes desired volume levels for each of the first and second sets of words that correspond with the first and second utterances. For example, a machine learning model may be trained using training examples to determine desired volume levels (and/or desired levels of one or more of intonation, pitch, accent) for sets of words in transcripts, and step  2010  may use the trained machine learning model to analyze the translated transcript and determine the desired volume level (and/or desired levels of one or more of intonation, pitch, accent) for each of the first and second sets of words. An example of such training example may include a transcript including a set of words, together with an indication of the desired volume level (and/or desired levels of one or more of intonation, pitch, and accent) for the set of words. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to determine desired volume levels (and/or desired levels of one or more of intonation, pitch, accent) for sets of words in transcripts, and step  2010  may use the artificial neural network to analyze the translated transcript and determine the desired volume level (and/or desired levels of one or more of intonation, pitch, accent) for each of the first and second sets of words. Additionally or alternatively, step  2010  may comprise determining the metadata information directly from the media stream received by step  2002 , wherein the metadata information includes desired volume levels for each of the first and second sets of words that correspond with the first and second utterances. For example, a machine learning model may be trained using training examples to determine desired volume levels (and/or desired levels of one or more of intonation, pitch, accent) for sets of words in media streams, and step  2010  may use the trained machine learning model to analyze the media stream received by step  2002  and determine the desired volume level (and/or desired levels of one or more of intonation, pitch, and accent) for each of the first and second sets of words. An example of such training example may include a media stream including a set of words, together with an indication of the desired volume level (and/or desired levels of one or more of intonation, pitch, and accent) for the set of words. In another example, an artificial neural network (such as a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to determine desired volume levels (and/or desired levels of one or more of intonation, pitch, and accent) for sets of words in media streams, and step  2010  may use the artificial neural network to analyze the media stream received by step  2002  and determine the desired volume level (and/or desired levels of one or more of intonation, pitch, and accent) for each of the first and second sets of words.

According to step  2106 , the processing device may translate the transcript of the media stream to a target language, wherein the translated transcript includes a first set of words in the target language that corresponds with the first utterance and a second set of words in the target language that corresponds with the second utterance. For example, step  2106  may use step  440  to translate or otherwise transform the transcript. In one example, step  2106  may translate or transformed speech directly from the media stream received by step  2102 , for example as described above in relation to step  440 . Additionally or alternatively, step  2106  may receive such translated transcript, for example by reading the translated transcript from memory, by receiving the translated transcript from an external device, by receiving the translated transcript from a user, and so forth.

Further, in some examples, step  2110  may determine the desired volume levels for each of the first and second sets of words based on the volume levels (and/or desired levels of one or more of intonation, pitch, and accent) in the media stream received by step  2102  for the corresponding segments. For example, the desired level may be a function of the level in the media stream. Some non-limiting examples of such function may include linear functions, non-linear functions, polynomial functions, functions determined using machine learning methods, and so forth. 
     The disclosed embodiment may further include using the determined voice profiles, the translated transcript, and the metadata information to artificially generate a revoiced media stream in which the first and second individual speak the translated transcript, wherein a ratio of the volume levels between the first and second sets of words in the revoiced media stream is substantially identical to the ratio of volume levels between the first and second utterances in the received media stream. In certain cases, the processing device may decide to select different values for utterances in the revoiced media stream. For example, a particular user with hearing disability that had a limited vocal range will received a revoiced media stream that generated to address his or her hearing disability. According to step  2112 , the processing device may use the determined voice profiles, the translated transcript, and the metadata information to artificially generate a revoiced media stream in which the first and second individual speak the translated transcript, wherein a ratio of the volume levels between the first and second sets of words in the revoiced media stream is substantially identical to the ratio of volume levels between the first and second utterances in the received media stream. For example, steps  2112  may use steps  444  and/or 446 to determine the synthesized voice and generate the revoiced media stream. 
     In disclosed embodiments, the voice profiles are further indicative of intonation differences between the first utterance as it was spoken by the first individual and the second utterance as it was spoken by the second individual. The processing device may generate a revoiced media stream in which intonation differences between the first and second sets of words in the revoiced media stream is substantially identical to the intonation differences between the first and second utterances in the received media stream. For example, the processing device may determine that the first utterance was said by the first individual as a question and the second utterance was said by the second individual as an answer. The processing device may generate a revoiced media stream in which the first set of words are said as a question and the second set of words are said as an answer. In disclosed embodiments, the voice profiles are further indicative of pitch differences between the first utterance as it was spoken by the first individual and the second utterance as it was spoken by the second individual. The processing device may generate a revoiced media stream in which pitch differences between the first and second sets of words in the revoiced media stream is substantially identical to the pitch differences between the first and second utterances in the received media stream. For example, the first individual is a child and the second is a grown up. 
     In disclosed embodiments, the voice profile is further indicative of accent differences between the first utterance as it was spoken by the first individual and the second utterance as it was spoken by the second individual. The processing device may generate a revoiced media stream in which accent differences between the first and second sets of words in the revoiced media stream is substantially identical to the accent differences between the first and second utterances in the received media stream. For example, the first individual speaks English with a Russian accent and the second individual speaks English without accent. In a revoiced media stream the first individual may speak Spanish with a Russian accent and the second individual speak Spanish without accent. Consistent with one example, the processing device is configured to identify that the first individual generally speak louder than the second individual. Accordingly, in the revoiced media stream, the first individual would say the first set of words in the target language louder than the second individual would say the second set of words in the target language.

As used herein, the term “sound-emanating object” may refer to any object capable of generating sounds within a range of between 10 to 30,000 hertz (e.g., between 20 to 20,000 hertz). Examples of sound-emanating objects may include different inanimate things (e.g., fans, speakers, traffic, wind, rain, etc.) and animate beings (e.g., people, animals). In related embodiments, when the sound-emanating object is another individual, the processing device is configured to translate what the other individual says to the target language. Disclosed embodiment includes revoicing the sounds that the sound-emanating object produce based on the target language or cultural norms associated with the target language. For example, in English animated dogs may be dubbed to bark woof woof and in Arabic animated dogs should be dubbed to bark hau, hau. Alternatively, the sound-emanating object is an inanimate object emanating sounds associated with a frequency range. The processing device is configured to adjust the sounds produced by the inanimate object emanating sounds to make it more perceptible to users. 
     Consistent with the present disclosure, the auditory relationship may be indicative of a ratio of pitch levels between utterances spoken by the individual in the original language and sounds from the sound-emanating object as they are recorded in the media stream.

Disclosed embodiments includes analyzing the media stream to determine volume levels for sounds from the sound-emanating object as they were recorded in the media stream, and to generate a revoiced media stream in which the sounds from the sound-emanating object are at lower levels of volume than the determined level of volume. For example, in some cases the sound-emanating object produce very loud voices and the processing device may include settings that define maximum volume in the revoiced media stream. Disclosed embodiments includes analyzing the media stream to identify sounds produced by the sound-emanating object that are known to cause discomfort to a particular user that the revoiced media stream is destined to and to reduce the volume level of the identified sounds. For example, reducing the sounds of gun shots to users that suffer from PTSD. 
     In some embodiments, the processing device may analyze the media stream to determine a set of audio profiles for a plurality of sound-emanating objects, and to: artificially generate a revoiced media stream in which a first ratio of the volume levels between utterances spoken by the individual in the target language and sounds from a first sound-emanating object is substantially identical to the ratio of volume levels between utterances spoken in the original language and sounds from the first sound-emanating object as they are recorded in the media stream, and a second ratio of the volume levels between utterances spoken by the individual in the target language and sounds from a second sound-emanating object is different from to the ratio of volume levels between utterances spoken in the original language and sounds from the second sound-emanating object as they are recorded in the media stream. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call, a video conference, or a recorded physical conversation) between the individual and a particular user. In some embodiments, the processing device may maintain the ratio of the volume levels between utterances spoken by the individual in the original language and sounds from a sound-emanating object in the revoiced media stream substantially identical to the ratio of volume levels between the utterances spoken by the individual in the target language and sounds from a sound-emanating object in the real-time conversation.

Thereafter, the system may determine auditory relationship between the individual and the sound-emanating object based on the voice profile and the audio profile, wherein the auditory relationship is indicative of a ratio of volume levels between utterances spoken by the individual in the original language and sounds from the sound-emanating object as they are recorded in the media stream. In the depicted example, the font size illustrates the volume level. Specifically, sound-emanating object  2222  emanates sounds loader than individual  113 . The system may artificially generate a revoiced media stream in which the individual speaks the translated transcript. In revoiced media stream  150 , the ratio of the volume levels between individual  113  and individual  116  in the revoiced media stream is substantially identical to the ratio of volume levels between utterances spoken in the original language spoken by individual  113  and sounds from sound-emanating object  2222  as they are recorded in the media stream. Also, sounds that the sound-emanating object produce may be translated based on the target language or cultural norms associated with the target language. For example, in English animated frogs may be dubbed to say Rabbit Rabbit and in Italian animated frogs should be dubbed to say Cra Cra. 
     17. Accounting for Timing Differences Between the Original Language and the Target Language 
       FIG.  23 A  is a flowchart of an example method  2300  for artificially generating a revoiced media stream in which the timing of the gaps in the utterances spoke in the origin language is adjusted to account for the determined timing differences between the original language and the target language. Consistent with the present disclosure, method  2300  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  2300 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including at least one individual speaking in an origin language. As described above, media receipt module  402  may receive a media stream from media owner  120  or a media stream captured by user  170 . According to step  2302 , the processing device may receive a media stream including at least one individual speaking in an origin language. For example, step  2302  may use step  432  and/or step  462  to receive the media stream. The disclosed embodiment may further include obtaining a transcript of the media stream including utterances spoke in the origin language. As described above, transcript processing module  404  may receive the transcript from media owner  120  or determine the transcript of the received media stream using any suitable voice-to-text algorithm. According to step  2304 , the processing device may obtain a transcript of the media stream including utterances spoke in the origin language. 
     The disclosed embodiment may further include analyzing the media stream to determine metadata information corresponding with the transcript of the media stream, wherein the metadata information includes timing data for the utterances and for the gaps between the utterances in the media stream. The metadata information may include details on timing as recorded in the media stream when the at least one individual speaks the original language. The metadata information may include details on the timing of utterances spoken by a plurality of individuals. According to step  2306 , the processing device may analyze the media stream to determine metadata information corresponding with the transcript of the media stream, wherein the metadata information includes timing data for the utterances and for the gaps between the utterances in the media stream. 
     The disclosed embodiment may further include determining timing differences between the original language and the target language, wherein the timing differences represent time discrepancy between saying the utterances in a target language and saying the utterances in the original language. In one example, saying a sentence in a target language takes more time than it takes to say the same sentence in the original language. In alternative example, saying a sentence in the target language takes less time than it takes to say the same sentence in the original language. According to step  2308 , the processing device may determine timing differences between the original language and the target language, wherein the timing differences represent time discrepancy between saying the utterances in a target language and saying the utterances in the original language. 
     The disclosed embodiment may further include determining at least one voice profile for the at least one individual. The determination of the voice profile may include a desired speaking speed for the at least one individual while speaking the target language. According to step  2310 , the processing device may determine at least one voice profile for the at least one individual. Additionally or alternatively, step  2310  may obtain the voice profile for the individual in other ways, for example using step  442 . 
     The disclosed embodiment may further include using the determined at least one voice profile, a translated version of the transcript, and the metadata information to artificially generate a revoiced media stream in which the at least one individual speaks in the target language in a manner than accounts for the determined timing differences between the original language and the target language. In certain cases, accounting for the determined timing differences between the original language and the target language may include adjusting the gaps between words spoken in the target language, adjusting the gaps between sentences spoken in the target language, or adjusting the speaking speed. According to step  2312 , the processing device may use the determined at least one voice profile, a translated version of the transcript, and the metadata information to artificially generate a revoiced media stream in which the at least one individual speaks in the target language in a manner than accounts for the determined timing differences between the original language and the target language. For example, steps  2312  may use steps  444  and/or  446  to determine the synthesized voice and generate the revoiced media stream. 
     In some embodiments, the processing device is configured to adjust the gaps between words spoken in the target language to account for the determined timing differences between the original language and the target language. For example, when dubbing a movie from a short duration language to a long duration language (e.g. an English movie dubbed to German) or from long to short (e.g. German to English), the target language speech audio usually needs to be time adjusted (stretched or shrunk) to fit in with the original movie’s timing. In other embodiments, the processing device is configured to adjust the gaps between sentences spoken in the target language to account for the determined timing differences between the original language and the target language. In one example, the processing device is configured to shorten the at least one gap before artificially generate utterances in the target language in the voice of the first individual. The at least one gap may be a gap between two words in a sentence or a gap between to words. In another example, the processing device is configured to widen the at least one gap before artificially generate utterances in the target language in the voice of the at least one individual. The at least one gap may be a gap between two words in a sentence or a gap between to words. 
     Consisting with the present disclosure, the processing device may use the at least one voice profile to determine a default time duration for each word in the translated version of the transcript spoken in the target language. The default time duration may be associated with the voice characteristics of the at least one individual. One character may speak slowly and other character may speak fast. The processing device may determine based on the metadata information to change the default time duration for the at least one individual. For example, the character that speaks slowly may need to speak slower (or faster) and the character that speaks fast may need faster (or lower) to account for the determined timing differences between the original language and the target language. In related embodiments, the processing device may determine to artificially generate a first utterance in the target language using the voice of the at least one individual, wherein the first utterance is recorded in a time shorter than the default time duration associated with the first utterance. In related embodiments, the processing device may determine to artificially generate a first utterance in the target language using the voice of the at least one individual, wherein the first utterance is recorded in a time longer than the default time duration associated with the first utterance. Simple homogeneous time stretching or shrinking isn’t usually good enough, and when squeezed or stretched to more than 20% from the revoiced media stream output, distortions and artifacts might appear in the resulting revoiced media stream. In order to minimize these distortions, the adjustments should not be homogeneous, but rather manipulate the gaps between words on a different scale than that used on the actual said utterance generated by the processing device. This can be done by directing the processing device to shorten or widen the gaps before pronouncing the sentence, and/or it can be done in the post process phase (by analyzing the resulting target language’s audio track signal for segments with volume lower than -60 dB, and minimizing, eliminating or widening their length by a major factor, e.g. by 80%) and then time adjusting (stretching or shrinking) the resulting audio track by a lower factor (e.g. only 10%), because the overall audio now needs less squeezing in order to fit the available movie timing. 
     In disclosed embodiments, the at least one individual includes a plurality of individuals and the processing device is configured to artificially generate a revoiced media stream in a first individual speaks in the target language faster than desired a talking speed included in a voice profile of the first individual in order to provide a second individual more time to speak in the target language. In disclosed embodiments, the at least one individual includes a plurality of individuals and the processing device is configured synchronize the timing data associated with the plurality of individuals to prevent a case where the plurality of individuals talk on top of each other when they speak the target language in the revoiced media stream. In disclosed embodiments, the processing device is configured to artificially generate a revoiced media stream in which sounds emanating from an object are shortened compared to the sounds in the original media stream in order to provide the at least one individual more time to speak in the target language. In disclosed embodiments, the processing device is configured to artificially generate a revoiced media stream in which volume levels of sounds emanating from an object are reduced compared to the volume level of sounds in the original media stream in order to provide the at least one individual more time to speak in the target language. Consistent with the present disclosure, the received media stream may be a real-time conversation (e.g., a phone call, a video conference, or a recorded physical conversation) between a plurality of individuals and a particular user. In some embodiments, the processing device may synchronize the timing data associated with the plurality of individuals to prevent a case where the plurality of individuals talk on top of each other when they speak the target language in the revoiced media stream. 
       FIG.  23 B  is a schematic illustration depicting an implementation of method  2300 . In the figure, original media stream  110  includes individual  113  and individual  116  that speak in English. Consistent with disclosed embodiments, the system may determine metadata information corresponding with the transcript of the media stream, wherein the metadata information includes timing data for the utterances and for the gaps between the utterances in the media stream. For example, the system may determine how much time it takes for individual  113  to say “[d]o you have food intolerance?” Thereafter, the system may determine how long it will take to say a translated version of the that sentence in German and artificially generate a revoiced media stream in which the individuals  113  and  116  speak in the target language in a manner than accounts for the determined timing differences between the original language and the target language. For example, individual  116  start talking in the revoiced media stream at 13:05 and not 13:03 (i.e., two seconds after the original time it starts in the original media stream). 
     18. Using Visual Data From Media Stream to Determine The Voice Profile of the Individual in the Media Stream 
       FIG.  24 A  is a flowchart of an example method  2400  for artificially generating a revoiced media stream and using visual data derived from the original media stream for determining the voice profile of the individual in the media stream. Consistent with the present disclosure, method  2400  may be executed by a processing device of system  100 . The processing device of system  100  may include a processor within a mobile communications device (e.g., mobile communications device  160 ) or a processor within a server (e.g., server  133 ) located remotely from the mobile communications device. Consistent with disclosed embodiments, a non-transitory computer-readable storage media is also provided. The non-transitory computer-readable storage media may store program instructions that when executed by a processing device of the disclosed system cause the processing device to perform method  2400 , as described herein. For purposes of illustration, in the following description reference is made to certain components of system  100 , system  500 , system  600 , and certain software modules in memory  400 . It will be appreciated, however, that other implementations are possible and that any combination of components or devices may be utilized to implement the exemplary method. It will also be readily appreciated that the illustrated method can be altered to modify the order of steps, delete steps, add steps, or to further include any detail described in the specification with reference to any other method disclosed herein. 
     A disclosed embodiment may include receiving a media stream including at least one individual speaking in an origin language.

     The disclosed embodiment may further include translating the transcript of the media stream to a target language. As mentioned above, transcript processing module  404  may include instructions to translate the transcript of the received media stream to the target language using any suitable translation algorithm. According to step  2406 , the processing device may translate the transcript of the media stream to a target language. For example, step  2406  may use step  440  to translate or otherwise transform the transcript. In one example, step  2406  may translate or transformed speech directly from the media stream received by step  2402 , for example as described above in relation to step  440 . Additionally or alternatively, step  2406  may receive a translated version of the transcript, for example by reading the translated version from memory, by receiving the translated version from an external device, by receiving the translated version from a user, and so forth. 
     The disclosed embodiment may further include analyzing the media stream to determine a set of voice parameters of the at least one individual and visual data.

The information from the visual data may affect the determination of the voice profile. For example, the contextual information may be used to determine emotional state of the at least one individual. Understanding the context of what the individual said will help translate the transcript more accurately and help generating a more authentic voice in the target language. According to step  2410 , the processing device may determine at least one voice profile for the at least one individual based on the set of voice parameters and the visual data. In another example, step  2410  may use step  442  to generate voice profile for the at least one individual from the media stream and/or the visual data included in the media stream received by step  2402 . 
     The disclosed embodiment may further include using the determined at least one voice profile and the translated transcript to artificially generate a revoiced media stream in which the at least one individual speaks in the target language. In some cases, the visual data may also assist in determining timing data needed for the generation of the revoiced media stream. According to step  2412 , the processing device may use the determined at least one voice profile and the translated transcript to artificially generate a revoiced media stream in which the at least one individual speaks in the target language. For example, steps  2412  may use steps  444  and/or 446 to determine the synthesized voice and generate the revoiced media stream.

For example, step  2910  may use object detection algorithms to detect the at least part of the item, and may stitch a depiction of the manipulated aspect of the item over the detected depiction of the at least part of the item in the video accessed by step  2902  (for example, using image and/or video stitching algorithms, using image and/or video matting algorithms, and so forth) to manipulate the video. 
     In some examples, the at least part of the video presented to the user by step  2904  may include no depiction of the first item and/or of the second item of step  2910 . In some examples, the at least part of the video presented to the user by step  2904  may include at least one depiction of the first item of step  2910  and/or at least one depiction of the second item of step  2910 . In some examples, the manipulation of an aspect of the depiction by step  2910  may comprise a manipulation of at least one frame of the video not included in the at least part of the video presented to the user by step  2904 . In some examples, the manipulation of an aspect of the depiction by step  2910  may comprise a manipulation of at least one frame of the video included in the at least part of the video presented to the user by step  2904 . 
     In some examples, method  2900  may analyze the video accessed by step  2902  to identify the first item and the second item (for example, using object detection algorithms and/or object recognition algorithms), and the user interface presented to the user by step  2906  may be based on the identified first item and the identified second item. For example, in response to a first identification result of the first item and the second item, step  2906  may present a first user interface to the user, and in response to a second identification result of the first item and the second item, step  2906  may present a second user interface to the user.

In some examples, the personalized profile may comprise information based, at least in part, on demographic information of the user. For example, the personalized profile may comprise information based, at least in part, on an age of the user (for example, based on an indication of the age of the user, such as an exact age, an age range, “young”, “old”, “child”, “teenager”, “young adult”, “adult”, “elderly”, “middle age”, and so forth), on a gender of the user, on a socioeconomic status of the user, and so forth. In some examples, the personalized profile may comprise information based, at least in part, on an emotional state of the user. Some non-limiting examples of indication of emotional state of the user may comprise “happy”, “sad”, “excited”, “tender”, “scared”, “angry”, and so forth. In some examples, the personalized profile may comprise indications of preferences of the user, such as an indication of a preferred hair style of the user, an indication of preferred measurements of the user, an indication of preferred colors (such as a preferred skin color, a preferred hair color, a preferred color scheme, and so forth), an indication of preferred style, an indication of preferred gender, an indication of preferred characters (such as preferred celebrities), and so forth. For example, past preferences and/or actions of the user may be used to generate the indications of preferences of the user included in the personalized profile. In another example, demographic information related to the user may be used to generate indications of preferences of the user included in the personalized profile, for example according to statistical data correlating demographic information with common preferences of users. 
     In some embodiments, step  3106  may comprise using the personalized profile obtained by step  3104  to select at least one characteristic of an avatar and/or of a character. For example, in response to a first personalized profile obtained by step  3104 , step  3106  may select a first at least one characteristic of the avatar and/or of the character, and in response to a second personalized profile obtained by step  3104 , step  3106  may select a second at least one characteristic of the avatar and/or of the character. In some examples, step  3104  may obtain a plurality of personalized profiles corresponding to a plurality of users, and step  3106  may select different characteristics of avatars and/or of characters for different users based on the personalized profiles corresponding to the different users. For example, step  3106  may select a first at least one characteristic of an avatar and/or of a character for a first user based on a first personalized profile corresponding to the first user, may select a second at least one characteristic of an avatar and/or of a character for a second user based on a second personalized profile corresponding to the second user, may select a third at least one characteristic of an avatar and/or of a character for a third user based on a third personalized profile corresponding to the third user, and so forth. In one example, a machine learning model may be trained using training examples to select characteristics of avatars and/or of characters based on profiles, and step  3106  may use the trained machine learning model to select the at least one characteristic of the avatar and/or of the character based on the personalized profile obtained by step  3104 . An example of such training example may include a particular profile, together with a label indicating a desired selection of at least one characteristic of the avatar and/or of the character in response to the particular profile. In another example, an artificial neural network may be configured to select characteristics of avatars and/or of characters based on profiles, and step  3106  may use the artificial neural network to select the at least one characteristic of the avatar and/or of the character based on the personalized profile obtained by step  3104 . In yet another example, step  3106  may use indications of preferences of the user included in the personalized profile obtained by step  3104  to select the at least one characteristic of the avatar and/or of the character, for example selecting an hair style for the avatar and/or for the character according to a preferred hair style of the user indicated in the personalized profile, or in another example, selecting a measurement of the avatar and/or of the character according to a preferred measurements of the user indicated in the personalized profile. 
     In some examples, the personalized profile obtained by step  3104  may include information based, at least in part, on a geographical location associated with the user (for example as described above), and step  3106  may select the at least one characteristic of the avatar and/or of the character based, at least in part, on the geographical location associated with the user. In one example, step  3106  may use statistical data correlating geographical locations with common preferences of users regarding characteristics of avatars and/or of characters to select characteristics of avatars and/or of characters that are likely to be preferred by the user based on the geographical location associated with the user (or based on the personalized profile including or based on the geographical location associated with the user). For example, the geographical location associated with the user may include a location of the user, a destination of the user, a location that the user showed interest in, a location of the home of the user, a hometown of the user, a work location of the user, a location frequent by the user, and so forth. In some examples, a machine learning model may be trained using training examples to select characteristic of avatars and/or of characters based on geographical locations, and step  3106  may use the trained machine learning model to select the at least one characteristic of the avatar and/or of the character based on the geographical location associated with the user. In some examples, an artificial neural network may be configured to select characteristic of avatars and/or of characters based on geographical locations, and step  3106  may use the artificial neural network to select the at least one characteristic of the avatar and/or of the character based on the geographical location associated with the user. 
     In some examples, the personalized profile obtained by step  3104  may include information based, at least in part, on a cultural association of the user (for example as described above), and step  3106  may select the at least one characteristic of the avatar and/or of the character based, at least in part, on the cultural association of the user. In one example, step  3106  may use statistical data correlating cultural association with common preferences of users regarding characteristics of avatars and/or of characters to select characteristics of avatars and/or of characters that are likely to be preferred by the user based on the cultural association of the user (or based on the personalized profile including or based on the cultural association of the user). For example, such cultural association of the user may include an association with at least one of a cultural tradition, an association with one or more observances, an association with one or more cultural customs, an association with one or more belief systems, an association with one or more cultural groups, and so forth. In some examples, a machine learning model may be trained using training examples to select characteristic of avatars and/or of characters based on cultural associations of users, and step  3106  may use the trained machine learning model to select the at least one characteristic of the avatar and/or of the character based on the cultural association of the user. In some examples, an artificial neural network may be configured to select characteristic of avatars and/or of characters based on cultural associations of users, and step  3106  may use the artificial neural network to select the at least one characteristic of the avatar and/or of the character based on the cultural association of the user. 
     In some examples, the personalized profile obtained by step  3104  may comprise information based, at least in part, on past behavior of the user, and step  3106  may select the at least one characteristic of the avatar and/or of the character based, at least in part, on the past behavior of the user. For example, statistical data correlating past behavior of users with common preferences of users regarding characteristics of avatars and/or of characters may be used to select characteristics of avatars and/or characters that are likely to be preferred by the user. For example, such past behavior of a user may include at least one of an action performed by the user, an activity corresponding to the user, an avoidance of an activity corresponding to the user, past selections made by the user, a selection of an avatar and/or of a character with a specific characteristic, an avoidance of avatars and/or of characters with a specific characteristic, and so forth. In one example, a past behavior of a user may include a selection of an avatar and/or a character with a specific characteristic, and in response, the at least one characteristic of the avatar and/or of the character may be selected to include the specific characteristic. In another example, a past behavior of a user may include avoiding avatars and/or characters with a specific characteristic, and in response, the at least one characteristic of the avatar and/or of the character may be selected to not include the specific characteristic.

Some non-limiting examples of indication of an age may include an exact age, an age range, “young”, “old”, “child”, “teenager”, “young adult”, “adult”, “elderly”, “middle age”, and so forth. For example, step  3106  may use statistical data correlating age with common preferences of users regarding characteristics of avatars and/or of characters to select characteristics of avatars and/or of characters that are likely to be preferred by the user. In some examples, a machine learning model may be trained using training examples to select characteristic of avatars and/or of characters based on ages of users, and step  3106  may use the trained machine learning model to select the at least one characteristic of the avatar and/or of the character based on the age of the user. In some examples, an artificial neural network may be configured to select characteristic of avatars and/or of characters based on ages of users, and step  3106  may use the artificial neural network to select the at least one characteristic of the avatar and/or of the character based on the age of the user. 
     In some examples, the personalized profile obtained by step  3104  may comprise information based, at least in part, on a demographic information of the user (such as age, gender, income level, socioeconomic status, etc.), and step  3106  may select the at least one characteristic of the avatar and/or of the character based, at least in part, on the demographic information of the user. For example, step  3106  may use statistical data correlating demographic information with common preferences of users regarding characteristics of avatars and/or of characters to select characteristics of avatars and/or of characters that are likely to be preferred by the user. In some examples, a machine learning model may be trained using training examples to select characteristic of avatars and/or of characters based on demographic information of users, and step  3106  may use the trained machine learning model to select the at least one characteristic of the avatar and/or of the character based on the demographic information of the user.

Some non-limiting examples of indication of emotional state of the user may comprise “happy”, “sad”, “excited”, “tender”, “scared”, “angry”, and so forth. For example, step  3106  may use statistical data correlating emotional state with common preferences of users regarding characteristics of avatars and/or of characters to select characteristics of avatars and/or of characters that are likely to be preferred by the user. In some examples, a machine learning model may be trained using training examples to select characteristic of avatars and/or of characters based on emotional states the users, and step  3106  may use the trained machine learning model to select the at least one characteristic of the avatar and/or of the character based on the emotional state of the user. In some examples, an artificial neural network may be configured to select characteristic of avatars and/or of characters based on emotional states the users, and step  3106  may use the artificial neural network to select the at least one characteristic of the avatar and/or of the character based on the emotional state of the user. 
     In some embodiments, step  3108  may comprise generating an output video using the at least one characteristic of an avatar selected by step  3106  by replacing at least part of the depiction of the person in the input video obtained by step  3102  with a depiction of an avatar, wherein the depiction of the avatar is according to the at least one characteristic of an avatar selected by step  3106 . In some examples, in response to a first at least one characteristic of an avatar selected by step  3106 , step  3108  may generate a first output video, and in response to a second at least one characteristic of an avatar selected by step  3106 , step  3108  may generate a second output video. The first output video may differ from the second output video, for example, the first output video may include a depiction of an avatar corresponding to the first at least one characteristic of an avatar, and the second output video may include a depiction of an avatar corresponding to the second at least one characteristic of an avatar. In some examples, step  3104  may obtain a plurality of personalized profiles corresponding to a plurality of users, step  3106  may select different characteristics of avatars for different users based on the personalized profiles corresponding to the different users, and step  3108  may generate different output videos for the different users, each generated output video may include a depiction of an avatar corresponding to the characteristics of an avatar selected by step  3106  for the user. For example, step  3108  may generate a first output video for a first user including a first depiction of an avatar corresponding to a first at least one characteristic of an avatar selected by step  3106  for the first user (for example, based on a first personalized profile corresponding to the first user), may generate a second output video for a second user including a second depiction of an avatar corresponding to a second at least one characteristic of an avatar selected by step  3106  for the second user (for example, based on a second personalized profile corresponding to the second user), may generate a third output video for a third user including a third depiction of an avatar corresponding to a third at least one characteristic of an avatar selected by step  3106  for the third user (for example, based on a third personalized profile corresponding to the third user), and so forth. 
     In some examples, step  3108  may identify a segment of the input video depicting the at least part of the depiction of the person, and the identified segment may be removed from the input video obtained by step  3102  and replaced with a depiction of the avatar (for example, using image and/or video stitching algorithms, using image and/or video matting algorithms, and so forth) to generate the output video. For example, to identify the segment of the input video depicting the at least part of the depiction of the person, step  3108  may use video segmentation algorithms, person detection algorithms, and so forth. In another example, a machine learning model may be trained using training examples to identify depictions of people in images and/or videos, and step  3108  may use the trained machine learning model to analyze the input video obtained by step  3102  and detect the segment of the input video depicting the at least part of the depiction of the person. An example of such training example may include an image and/or a video, together with a label indicating a segment of the image and/or video depicting a person. 
     In some examples, a machine learning model may be trained using training examples to replace depictions of people (or parts of such depictions) in images and/or videos with depictions of avatars based on selected characteristics of the avatars, and step  3108  may use the trained machine learning model to analyze the input video obtained by step  3102  and replace the at least part of the depiction of the person in the input video with the depiction of an avatar based on the at least one characteristic of an avatar selected by step  3106 . An example of such training example may include a video including a depiction of a person, with some selected characteristics of an avatar, together with a desired output video including a depiction of an avatar that is according to the selected characteristics of an avatar replacing at least part of the depiction of the person in the video.

In some implementations, one or more steps illustrated in  FIG.  32    may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. 
     In some embodiments, step  3202  may comprise obtaining input video including at least a depiction of two or more persons. Some non-limiting examples of the people depicted in the input video may include a news anchor, a weatherperson, an actor, a person known to the user of method  3200 , a family member of the user of method  3200 , a person unknown to the user of method  3200 , a celebrity, and so forth. For example, step  3202  may read at least part of the video from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive at least part of the video from an external device (for example through communications network  140 ), may receive at least part of the video using media receipt module  402 , may capture at least part of the video using one or more image sensors (for example, using camera subsystem  220  and/or optical sensor  222 ), and so forth. In some examples, the video may be encoded in any suitable format. Some non-limiting examples of such formats may include uncompressed video formats, lossless compressed video formats, lossy compressed video formats, and so forth. In one example, the obtained video may include audio data. In another example, the obtained video by step  3202  may include no audio data. In one example, step  3202  may obtain video that is recorded from an environment. In another example, step  3202  may obtain video that is artificially synthesized. In one example, step  3202  may obtain the video after the recording of the video was completed. In another example, step  3202  may obtain the video in real-time, while the video is being produced and/or recorded. In some examples, step  3202  may use step  462  to obtain the video. 
     In some embodiments, step  3206  may comprise analyzing the input video obtained by step  3202  to determine at least one property for each person of a group of at least two persons of the two or more persons depicted in the input video. Some non-limiting examples of such properties of a person may include identity of a person, properties of a depiction of the person in the input video, color (such as hair color, skin color, eyes color, color of a clothing item, color of at least one pixel of a depiction of the person, etc.), texture (such as texture of at least part of a depiction of the person, texture of a body part of the person, etc.), shape of at least part of a depiction of the person (such as shape of a depiction of a body part of the person, shape of the entire depiction of the person, shape of a body part of the person, shape of the body of the person, 2D shape, 3D shape, etc.), size of at least part of a depiction of the person (such as size in pixels, relative size, size of a depiction of a body part of the person, size of the entire depiction of the person, etc.), real world size of at least part of the person (such as actual measurement, estimated size, relative size, size of a body part of the person, size of the entire person, etc.), demographic information of the person (such as age, gender, socioeconomic status, income level, etc.), information related to at least one clothing item worn by the person in the input video (such as type of the clothing item, color of clothing item, etc.), information related to a modesty level of the person in the input video, information related to an emotional state of the person in the input video, properties of the face of the person, and so forth. Some other non-limiting examples of such properties of a person and/or of a depiction of the person are described above. In one example, step  3206  may use face recognition algorithms to determine an identity for at least one person of the group of at least two persons, and step  3206  may further use the determined identity for a person to determine at least one property for the person. In another example, a machine learning model may be trained using training examples to determine properties of people from images and/or videos, and step  3206  may use the trained machine learning model to analyze the input video obtained by step  3202  to determine the at least one property for at least one person of the group of at least two persons. An example of such training example may include an image and/or a video depicting a person, together with a label indicating one or more properties of the depicted person. In yet another example, an artificial neural network (such as convolutional neural network, deep neural network, etc.) may be configured to determine properties of people from images and/or videos, and step  3206  may use the artificial neural network to analyze the input video obtained by step  3202  to determine the at least one property for at least one person of the group of at least two persons. 
     In some embodiments, step  3208  may comprise using the personalized profile obtained by step  3104  and the properties determined by step  3206  to select a first person of the group of at least two persons, where the group of at least two persons also includes at least a second person. For example, in response to a first personalized profile obtained by step  3104  and first properties determined by step  3206 , step  3208  may select one person of the group of at least two persons as the first person, and in response to a second personalized profile obtained by step  3104  and the first properties determined by step  3206 , step  3208  may select a different person of the group of at least two persons as the first person. In another example, in response to a first information included in the personalized profile obtained by step  3104  and first properties determined by step  3206 , step  3208  may select one person of the group of at least two persons as the first person, and in response to a second information included in the personalized profile obtained by step  3104  and the first properties determined by step  3206 , step  3208  may select a different person of the group of at least two persons as the first person. Some non-limiting examples of such information included in the personalized profile are described above. In yet another example, a machine learning model may be trained using training examples to select persons of groups of people based on personalized profiles and properties of people in the groups of people, and step  3208  may use the trained machine learning model to analyze the personalized profile obtained by step  3104  and the properties determined by step  3206  to select the first person of the group of at least two persons. An example of such training example may include a personalized profile (for example, as described above) and properties of people from a group of people, together with a label indicating a selection of a particular person of the group of people.

For example, step  3210  may use method  3100  to replace the at least part of the depiction of the first person selected by step  3208  with an avatar in the input video obtained by step  3202  and generate the output video. In another example, a machine learning model may be trained using training examples to replace depictions of particular persons in videos, and step  3210  may use the trained machine learning model to analyze the input video obtained by step  3202  and replace the at least part of the depiction of the first person selected by step  3208  with an avatar while leaving the depiction of the second person in the input video obtained by step  3202  to generate the output video. An example of such training example may include a video depicting two or more persons and an indication of one of the two or more persons, together with a desired video to be generated in which the depiction of the indicated person is replaced by an avatar and the depiction of other people in the video is not replaced. In an additional example, an artificial neural network (such as convolutional neural network, deep neural network, etc.) may be configured to replace depictions of particular persons in videos, and step  3210  may use the artificial neural network to analyze the input video obtained by step  3202  and replace the at least part of the depiction of the first person selected by step  3208  with an avatar while leaving the depiction of the second person in the input video obtained by step  3202  to generate the output video. For example, Generative Adversarial Networks (GAN) may be used to train the artificial neural network. In some examples, step  3210  may analyze the input video obtained by step  3202  to detect the depiction of the first person selected by step  3208 , and replace the detected depiction with a depiction of an avatar (for example, using image and/or video stitching algorithms, using image and/or video matting algorithms, and so forth) to generate the output video.

       FIG.  33    is a flowchart of an example method  3300  for generating personalized videos with selective replacement of text, in accordance with some embodiments of the disclosure. In this example, method  3300  may comprise: obtaining input video including at least a depiction of a text (step  3302 ); obtaining a personalized profile associated with a user (step  3104 ); analyzing the input video to determine at least one property of the depiction of the text (step  3306 ); and using the personalized profile and the at least one property of the depiction of the text to modify the text in the input video to generate an output video (step  3308 ). For example, the user may be a prospective viewer of the output video, may be a photographer of at least part of an input video, may be an editor of at least part of the manipulated video, and so forth. In some implementations, method  3300  may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. In some implementations, one or more steps illustrated in  FIG.  33    may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. 
     In some embodiments, step  3302  may comprise input video including at least a depiction of a text. For example, step  3302  may read at least part of the video from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive at least part of the video from an external device (for example through communications network  140 ), may receive at least part of the video using media receipt module  402 , may capture at least part of the video using one or more image sensors (for example, using camera subsystem  220  and/or optical sensor  222 ), and so forth. In some examples, the video may be encoded in any suitable format. Some non-limiting examples of such formats may include uncompressed video formats, lossless compressed video formats, lossy compressed video formats, and so forth. In one example, the obtained video may include audio data. In another example, the obtained video by step  3302  may include no audio data. In one example, step  3302  may obtain video that is recorded from an environment. In another example, step  3302  may obtain video that is artificially synthesized. In one example, step  3302  may obtain the video after the recording of the video was completed. In another example, step  3302  may obtain the video in real-time, while the video is being produced and/or recorded. In some examples, step  3302  may use step  462  to obtain the video. 
     In some embodiments, step  3306  may comprise analyzing the input video obtained by step  3302  to determine at least one property of the depiction of the text. Some non-limiting examples of such properties of the depiction of the text may include the textual information presented in the depiction of the text, information based on the textual information (a language register of the text, a language of the text, etc.), a name included in the text, information based on the name, color of at least part of the depiction of the text, background color of at least part of the depiction of the text, size of at least part of the depiction of the text, font of at least part of the depiction of the text, texture of the least part of the depiction of the text, background texture of at least part of the depiction of the text, a property of a contour associated with at least part of the depiction of the text, a property of a location within the input video associated with at least part of the depiction of the text, and so forth. In one example, step  3306  may use OCR algorithms to determine textual information presented in the depiction of the text, and step  3306  may further use the determined textual information to determine at least one property for the depiction of the text. For example, the at least one property may include the determined textual information, information based on an analysis of the textual information (for example, using NLP algorithms), and so forth. In another example, a machine learning model may be trained using training examples to determine properties of depictions of text from images and/or videos, and step  3306  may use the trained machine learning model to analyze the input video obtained by step  3302  to determine the at least one property of the depiction of the text. An example of such training example may include an image and/or a video depicting a text, together with a label indicating one or more properties of the depicted text. In yet another example, an artificial neural network (such as convolutional neural network, deep neural network, etc.) may be configured to determine properties of depictions of text from images and/or videos, and step  3306  may use the artificial neural network to analyze the input video obtained by step  3302  to determine the at least one property of the depiction of the text. 
     In some embodiments, step  3308  may comprise using the personalized profile obtained by step  3104  and the at least one property of the depiction of the text determined by step  3306  to modify the text in the input video obtained by step  3302  to generate an output video. In some examples, in response to a first combination of personalized profile obtained by step  3104  and at least one property of the depiction of the text determined by step  3306 , step  3308  may generate a first output video, and in response to a second combination of personalized profile obtained by step  3104  and at least one property of the depiction of the text determined by step  3306 , step  3308  may generate a second output video. In some examples, in response to a first of personalized profile obtained by step  3104  and the at least one property of the depiction of the text determined by step  3306 , step  3308  may generate the first output video, and in response to a second personalized profile obtained by step  3104  and the same at least one property of the depiction of the text determined by step  3306 , step  3308  may generate the second output video. The second output video may differ from the first output video. In some examples, the first output video may include a first depiction of a first modified version of the text, and the second video may include a second depiction of a second modified version of the text. In one example, the textual information of the first modified version of the text may differ from the textual information of the second modified version of the text. In another example, the textual information of the first modified version of the text may be identical to the textual information of the second modified version of the text, and the first depiction of a first modified version of the text may differ from the second depiction of a second modified version of the text (for example, in at least one of text color, background color, text texture, background texture, size, font, location within the output video, curvature of the depiction, and so forth). For example, step  3308  may generate the textual information for the modified version of the text using the personalized profile obtained by step  3104  and the at least one property of the depiction of the text determined by step  3306 . For example, in response to a first combination of personalized profile obtained by step  3104  and at least one property of the depiction of the text determined by step  3306 , step  3308  may generate first textual information for the modified version of the text, and in response to a second combination of personalized profile obtained by step  3104  and at least one property of the depiction of the text determined by step  3306 , step  3308  may generate second textual information for the modified version of the text, the second textual information may differ from the first textual information. 
     In some examples, step  3104  may obtain a plurality of personalized profiles corresponding to a plurality of users, and step  3308  may generate different output videos for the different users, the generated different output video may include different depictions of the same textual information or different depictions of different textual information. For example, step  3308  may generate a first output video for a first user including a first depiction of text (for example, based on a first personalized profile corresponding to the first user), may generate a second output video for a second user including a second depiction of text (for example, based on a second personalized profile corresponding to the second user), may generate a third output video for a third user including a third depiction of text (for example, based on a third personalized profile corresponding to the third user), and so forth. 
     In some examples, step  3308  may identify a segment of the input video obtained by step  3302  including at least part of the depiction of the text, and the identified segment may be removed from the input video obtained by step  3302  and replaced with a depiction of the modified text (for example, using image and/or video stitching algorithms, using image and/or video matting algorithms, and so forth) to generate the output video. For example, to identify the segment of the input video including the at least part of the depiction of the text, step  3308  may use video segmentation algorithms, OCR algorithms, text detection algorithms, and so forth. In another example, a machine learning model may be trained using training examples to identify depictions of text in images and/or videos, and step  3308  may use the trained machine learning model to analyze the input video obtained by step  3302  and detect the segment of the input video including the at least part of the depiction of the text. An example of such training example may include an image and/or a video, together with a label indicating a segment of the image and/or video depicting text (or depicting a particular text). 
     In some examples, a machine learning model may be trained using training examples to replace depictions of text (or parts of such depictions) in images and/or videos with depictions of modified text based on properties of the text and/or personalized profiles, and step  3308  may use the trained machine learning model to analyze the input video obtained by step  3302  and replace the depiction of the text in the input video with the depiction of the modified text based on the personalized profile obtained by step  3104  and/or the at least one property of the depiction of the text determined by step  3306 . An example of such training example may include a video including a depiction of a text, possibly with properties of the text and/or a personalized profile, together with a desired output video including a depiction of a modified text. In some examples, an artificial neural network (such as convolutional neural network, deep neural network, etc.) may be configured to replace depictions of text (or parts of such depictions) in images and/or videos with depictions of modified text based on properties of the text and/or personalized profiles, and step  3308  may use the the artificial neural network to analyze the input video obtained by step  3302  and replace the depiction of the text in the input video with the depiction of the modified text based on the personalized profile obtained by step  3104  and/or the at least one property of the depiction of the text determined by step  3306 . For example, Generative Adversarial Networks (GAN) may be used to train such artificial neural network. 
     In some examples, the modified text of step  3308  may include parts of the text of the input video of step  3302  (for example, at most 80%, at most 60%, at most 40%, at most 20%, at most 10%, at most 5%, at most 1%, at least 5%, at least 10%, at least 20%, at least 40%, at least 60%, at least 80%, and so forth). 
     In some examples, systems and methods for generating personalized videos with selective replacement of text are provided. In some examples, input video including at least a depiction of a text may be obtained. Further, a personalized profile associated with a user may be obtained. The input video may be analyzed to determine at least one property of the depiction of the text. Further, the personalized profile and/or the at least one property of the depiction of the text may be used to modify the text in the input video and generate an output video. For example, the user may be a prospective viewer of the output video, may be a photographer of at least part of the input video, may be an editor of at least part of the input video, and so forth.

In this example, method  3400  may comprise: obtaining input video including at least a background (step  3402 ); obtaining a personalized profile associated with a user (step  3104 ); analyzing the input video to identify a portion of the input video depicting the background (step  3406 ); using the personalized profile to select a modification of the background (step  3408 ); and using the selected modification of the background and the identified portion of the input video to modify a depiction of the background in the input video to generate an output video (step  3410 ). For example, the user may be a prospective viewer of the output video, may be a photographer of at least part of an input video, may be an editor of at least part of the manipulated video, and so forth. In some implementations, method  3400  may comprise one or more additional steps, while some of the steps listed above may be modified or excluded.

     In some embodiments, step  3402  may comprise obtaining input video including at least a background. For example, step  3402  may read at least part of the video from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive at least part of the video from an external device (for example through communications network  140 ), may receive at least part of the video using media receipt module  402 , may capture at least part of the video using one or more image sensors (for example, using camera subsystem  220  and/or optical sensor  222 ), and so forth.

In one example, step  3402  may obtain the video after the recording of the video was completed. In another example, step  3402  may obtain the video in real-time, while the video is being produced and/or recorded. In some examples, step  3402  may use step  462  to obtain the video. 
     In some embodiments, step  3406  may comprise analyzing the input video obtained by step  3402  to identify a portion of the input video depicting the background. For example, step  3406  may use foreground detection algorithms to separate the foreground from the background of the input video obtained by step  3402 , therefore identifying the background. In another example, a machine learning model may be trained using training example to identify portions of videos depicting backgrounds, and step  3402  may use the trained machine learning model to analyze the input video obtained by step  3402  and identifying the portion of the input video depicting the background.

       FIG.  35    is a flowchart of an example method  3500  for generating personalized videos from textual information, in accordance with some embodiments of the disclosure. In this example, method  3500  may comprise: obtaining textual information (step  3502 ); obtaining a personalized profile associated with a user (step  3104 ); using the personalized profile to select at least one characteristic of a character (step  3106 ); and using the textual information and the selected at least one characteristic of the character to generate an output video depicting a character with the selected at least one characteristic of the character (step  3508 ). For example, the user may be a prospective viewer of the output video, may be a photographer of at least part of an input video, may be an editor of at least part of the manipulated video, and so forth. In some implementations, method  3500  may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. In some implementations, one or more steps illustrated in  FIG.  35    may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. 
     In some embodiments, step  3502  may comprise obtaining textual information. For example, step  3502  may read at least part of the textual information from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive at least part of the textual information from an external device (for example through communications network  140 ), may receive at least part of the textual information from a user, and so forth. In some examples, the textual information may be encoded in any suitable format. Some non-limiting examples of such formats may include uncompressed text formats, compressed text formats, and so forth. In some examples, step  3502  may obtain textual information that is automatically generated. In one example, step  3502  may use at least one of step  440 , text analysis unit  635 , step  704 , step  706 , step  804 , step  904 , step  1004 , step  1104 , step  1110 , step  1204 , step  1208 , step  1304 , step  1308 , step  1404 , step  1408 , step  1504 , step  1508 , step  1602 , step  1608 , step  1702 , step  1708 , step  1802 , step  1808 , step  1904 , step  1908 , step  2004 , step  2006 , step  2104 , step  2106 , step  2204 , step  2206 , step  2304 , step  2404 , step  2406 , step  2504 , step  2508 , step  2604 , step  2606 , step  3306 , step  3608 , step  3708 , step  3806 , etc., to generate the textual information. For example, the textual information obtained by step  3502  may include at least one of a script, a translation of another text, a transcript, of a weather forecast, a news update, a description of an event, a description of an action, a description of an environment, and so forth. 
     In some embodiments, step  3508  may comprise using the textual information obtained by step  3502  and the at least one characteristic of the character selected by step  3106  to generate an output video depicting a character with the selected at least one characteristic of the character. For example, a machine learning model may be trained using training examples to generate videos depicting characters based on textual information and selected characteristics of the characters, and step  3508  may use the trained machine learning model to use the textual information obtained by step  3502  and the at least one characteristic of the character selected by step  3106  to generate the output video depicting the character with the selected at least one characteristic of the character. In another example, an artificial neural network (such as convolutional neural network, deep neural network, a recurrent neural network, a long short-term memory neural network, a deep neural network, etc.) may be configured to generate videos depicting characters based on textual information and selected characteristics of the characters, and step  3508  may use the artificial neural network to use the textual information obtained by step  3502  and the at least one characteristic of the character selected by step  3106  to generate the output video depicting the character with the selected at least one characteristic of the character. For example, Generative Adversarial Networks (GAN) may be used to train such artificial neural network. In some examples, in response to a first combination of the textual information obtained by step  3502  and the at least one characteristic of the character selected by step  3106 , step  3508  may generate a first output video, and in response to a second combination of the textual information obtained by step  3502  and the at least one characteristic of the character selected by step  3106 , step  3508  may generate a second output video, the second output video may differ from the first output video. In one example, in response to a first textual information obtained by step  3502  and the at least one characteristic of the character selected by step  3106 , step  3508  may generate a first output video depicting a character with the at least one characteristic of the character behaving according to the first textual information, and in response to a second textual information obtained by step  3502  and the same at least one characteristic of the character, step  3508  may generate a second output video depicting the same character with the at least one characteristic of the character behaving according to the second textual information. In one example, in response to a textual information obtained by step  3502  and a first at least one characteristic of the character selected by step  3106 , step  3508  may generate a first output video depicting a first character (with the at least one characteristic of the character) behaving according to the textual information, and in response to the same textual information and a second at least one characteristic of the character selected by step  3106 , step  3508  may generate a second output video depicting a second character (with the second at least one characteristic of the character) behaving identically or similarly to the first character. 
     In some examples, step  3508  may generate an output video depicting a character with the at least one characteristic of the character selected by step  3106  behaving according to the textual information obtained by step  3502 . Some non-limiting examples of such behaviors may include performance of one or more actions (for example, pointing at a particular object, sitting, standing, walking, looking in a particular direction, using a particular device, holding a particular object, etc.), saying particular words (for example, reading a script, engaging in a dialog, etc.), using a selected body language, and so forth. For example, the textual information obtained by step  3502  may include a description of the desired behavior of the character, desired actions to be performed by the character, desired text to be read by the character, and so forth. 
     In some examples, the textual information obtained by step  3502  may comprise at least a text to be spoken by the character, and step  3508  may generate output video depicting the character with the selected at least one characteristic saying the text. In one example, method  3500  may analysis of the text (for example using an NLP algorithm) to determine a desired facial expression and/or a desired gesture (such as a hand gesture, body language gesture, a body pose gesture, a particular motion gesture, etc.) of the character corresponding to a particular portion of the text, and step  3508  may generate output video depicting the character with the selected at least one characteristic using the determined desired facial expression and/or the determined desired gesture while saying the particular portion of the text. 
     In some examples, the textual information obtained by step  3502  may comprise at least a description of an action of the character, and step  3508  may generate output video depicting the character with the selected at least one characteristic performing the described action. In some examples, the textual information obtained by step  3502  may comprise at least a description of a location of the character, and step  3508  may generate output video depicting the character with the selected at least one characteristic at the described location. For example, the description of the location may be used to generate background for the character, and the character may be placed over the background (for example, using image and/or video stitching algorithms, using image and/or video matting algorithms, and so forth) to generate the output video. 
     In some examples, the textual information obtained by step  3502  may comprise at least a dialog between two characters. Further, in some examples, method  3500  may further use the personalized profile obtained by step  3104  and/or the dialog to select at least one characteristic of a second character. For example, an analysis of the dialog (for example, using NLP algorithms) may indicate characteristics of the second character, for example indicating that the second charter is a female, is a male, is a child, is an elderly person, is a businesswoman, and so forth. In another example, method  3500  may use step  3106  to select at least one characteristic of a second character based on the personalized profile obtained by step  3104 . In yet another example, in response to a first combination of personalized profile obtained by step  3104  and the dialog, a first at least one characteristic of the second character may be selected, and in response to a second combination of personalized profile obtained by step  3104  and the dialog, a second at least one characteristic of the second character may be selected. Further, in some examples, method  3500  may generate the output video to depict the character with the at least one characteristic of the character selected by step  3106  speaking, according to the dialog, with the second character with the selected at least one characteristic of the second character, for example using a trained machine learning model and/or an artificial neural network as described above. 
     In some examples, method  3500  may use the personalized profile obtained by step  3104  to select a background. For example, step  3408  may be used to select the background based on the personalized profile. In another example, in response to a first personalized profile obtained by step  3104 , a first background may be selected, and in response to a second personalized profile obtained by step  3104 , a second background may be selected, the second background may differ from the first background. Further, in some examples, step  3508  may generate the output video to depict the character with the selected at least one characteristic over the selected background, for example by placing the character over the selected background (for example, using image and/or video stitching algorithms, using image and/or video matting algorithms, and so forth) to generate the output video. 
     In some examples, method  3500  may use the personalized profile obtained by step  3104  to select an object. For example, in response to a first personalized profile obtained by step  3104 , a first object may be selected, and in response to a second personalized profile obtained by step  3104 , a second object may be selected, the second object may differ from the first object. Further, in some examples, step  3508  may generate the output video to depict the character with the selected at least one characteristic interacting with the selected object, for example using a trained machine learning model and/or an artificial neural network as described above. Some non-limiting examples of such interactions may include holding the object, throwing the object, throwing an item at the object, looking at the object, pointing at the object, and so forth.

Further, in some examples, a personalized profile associated with a user may be obtained. Further, in some examples, the personalized profile may be used to select at least one characteristic of a character. Further, in some examples, the textual information may be used to generate an output video using the selected at least one characteristic of the character. For example, the user may be a prospective viewer of the output video, may be an editor of at least part of the output video, and so forth. 
     In some examples, the output video may be displayed to the user, may be stored in memory, may be transmitted over a communication network using a communication device, may be provided to an external device, may be posted on a blockchain, may be posted on a website, and so forth.

For examples, the textual information may be read from memory, received through a communication network using a communication device, received from an external device, generated, and so forth. In some examples, a personalized profile associated with a user may be obtained. For example, the personalized profile may be obtained as described above.

For example, step  3708  may generate a personalized script that includes references to historical events from the lifetime of the user. In another example, step  3708  may generate a personalized script that includes references to life events common at the age of the user. 
     In some examples, the personalized profile obtained by step  3104  may be based, at least in part, on an emotional state of the user, and Step  3708  may generate the personalized script based, at least in part, on the emotional state of the user.

     In some embodiments, step  3802  may comprise receiving an image containing a first region. Some non-limiting examples of such regions are described below. For example, step  3802  may read at least part of the image from memory (for example, from data structure  126 , from data structure  136 , from memory  250 , from memory  320 , from memory  400 , etc.), may receive at least part of the image from an external device (for example through communications network  140 ), may receive at least part of the image using media receipt module  402 , may capture at least part of the image using one or more image sensors (for example, using camera subsystem  220  and/or optical sensor  222 ), may generate at least part of the image, and so forth. In some examples, the image may be encoded in any suitable format. Some non-limiting examples of such formats may include uncompressed image formats, lossless compressed image formats, lossy compressed image formats, and so forth. In one example, step  3802  may obtain image that is captured from an environment. In another example, step  3802  may obtain image that is artificially synthesized. 
     In some examples, step  3802  may use step  3104  to obtain a personalized profile associated with a user, and may use the personalized profile obtained by step  3104  to select the first region of the image. For example, in response to a first personalized profile, step  3802  may select one region of the image as the first region of the image, and in response to a second personalized profile, step  3802  may select a different region of the image as the first region of the image.

     In some embodiments, step  3806  may comprise receiving a script containing a first segment of the script. For example, the first segment of the script may be related to the first region of the image. For example, the first segment may include a description of the first region of the image, may include a discussion of information related to the first region of the image, may include a reference to the first region of the image, and so forth.
