Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to and the benefit of U.S. Provisional Application Patent Ser. No. 63/136,380 filed Jan. 12, 2021, the entire disclosure of which is hereby incorporated by reference. 
    
    
     TECHNICAL FIELD 
     This disclosure relates to content navigation. More specifically, this disclosure relates to methods and systems for navigating tags on time-synchronized content. 
     BACKGROUND 
     Content items (e.g., songs, movies, videos, podcasts, transcriptions, etc.) are conventionally played via a computing device, such as a smartphone, laptop, desktop, television, or the like. Navigating the content items is conventionally performed by using a seek bar, fast-forward button, and/or rewind button. Oftentimes, a user may use a see bar to attempt to find a portion of a content item they desire to play. The user may have to scroll back and forth using the seek bar until the desired portion of the content item is found. Accordingly, conventional navigation is inaccurate, time-consuming, inefficient, and resource-wasteful. 
     SUMMARY 
     In one embodiment, a computer-implemented method for editing navigation of a content item is disclosed. The method may include presenting, via a user interface at a client computing device, time-synchronized text pertaining to the content item; receiving an input of a tag for the time-synchronized text of the content item; storing the tag associated with the time-synchronized text of the content item; and responsive to receiving a request to play the content item: playing the content item via a media player presented in the user interface, and concurrently presenting the time-synchronized text and the tag as a graphical user element in the user interface. 
     In one embodiment, a computer-implemented method for a client device presenting a media player is disclosed. The computer-implemented method includes receiving a content item comprising a plurality of tags associated with a plurality of time-synchronized text items; presenting, in a first portion of a user interface, the plurality of time-synchronized text items; presenting, in a second portion of the user interface, the plurality of tags associated with the plurality of time-synchronized text items, wherein each of the plurality of tags presents a tag identity and a timestamp associated with a respective time-synchronized text item; receiving, via the user interface, a selection of a first tag of the plurality of tags associated with the plurality of time-synchronized text items; and causing a media player to begin playback of the content item at the timestamp for a time-synchronized text item corresponding to the selected first tag. 
     In one embodiment, a computer-implemented method for a server device to associate tags with time-synchronized text items of a content item is disclosed. The computer-implemented method includes generating time-synchronized text corresponding to audio of a content item; causing, via a user interface at a client computing device, presentation of the time-synchronized text pertaining to the content item; receiving an input of a tag for the time-synchronized text of the content item; storing the tag associated with the time-synchronized text of the content item; and responsive to receiving a request to play the content item: causing playback of the content item via a media player presented in the user interface, and concurrently causing presentation of the time-synchronized text and the tag as a graphical user element in the user interface. 
     In one embodiment, a tangible, non-transitory computer-readable medium stores instructions that, when executed, cause a processing device to perform any operation of any method disclosed herein. 
     In one embodiment, a system includes a memory device storing instructions and a processing device communicatively coupled to the memory device. The processing device executes the instructions to perform any operation of any method disclosed herein. 
     Other technical features may be readily apparent to one skilled in the art from the following figures, descriptions, and claims.

     NOTATION AND NOMENCLATURE 
     Various terms are used to refer to particular system components. Different entities may refer to a component by different names—this document does not intend to distinguish between components that differ in name but not function. In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to . . . .” Also, the term “couple” or “couples” is intended to mean either an indirect or direct connection. Thus, if a first device couples to a second device, that connection may be through a direct connection or through an indirect connection via other devices and connections. 
     The terminology used herein is for the purpose of describing particular example embodiments only, and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed. 
     The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections; however, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms, when used herein, do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments. The phrase “at least one of,” when used with a list of items, means that different combinations of one or more of the listed items may be used, and only one item in the list may be needed. For example, “at least one of: A, B, and C” includes any of the following combinations: A, B, C, A and B, A and C, B and C, and A and B and C. In another example, the phrase “one or more” when used with a list of items means there may be one item or any suitable number of items exceeding one. 
     Moreover, various functions described below can be implemented or supported by one or more computer programs, each of which is formed from computer readable program code and embodied in a computer readable medium. The terms “application” and “program” refer to one or more computer programs, software components, sets of instructions, procedures, functions, objects, classes, instances, related data, or a portion thereof adapted for implementation in a suitable computer readable program code. The phrase “computer readable program code” includes any type of computer code, including source code, object code, and executable code. The phrase “computer readable medium” includes any type of medium capable of being accessed by a computer, such as read only memory (ROM), random access memory (RAM), a hard disk drive, a compact disc (CD), a digital video disc (DVD), solid state drives (SSDs), flash memory, or any other type of memory. A “non-transitory” computer readable medium excludes wired, wireless, optical, or other communication links that transport transitory electrical or other signals. A non-transitory computer readable medium includes media where data can be permanently stored and media where data can be stored and later overwritten, such as a rewritable optical disc or an erasable memory device. 
     Definitions for other certain words and phrases are provided throughout this patent document. Those of ordinary skill in the art should understand that in many if not most instances, such definitions apply to prior as well as future uses of such defined words and phrases. 
     DETAILED DESCRIPTION 
     The following discussion is directed to various embodiments of the disclosed subject matter. Although one or more of these embodiments may be preferred, the embodiments disclosed should not be interpreted, or otherwise used, as limiting the scope of the disclosure, including the claims. In addition, one skilled in the art will understand that the following description has broad application, and the discussion of any embodiment is meant only to be exemplary of that embodiment, and not intended to intimate that the scope of the disclosure, including the claims, is limited to that embodiment. 
       FIGS. 1 through 10 , discussed below, and the various embodiments used to describe the principles of this disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. 
     Interaction with digital media (e.g., content items) has remained stagnant for a long time. The term “content item” as used herein may refer to a song, movie, video, clip, podcast, audio, transcription, or any suitable multimedia. To play a content item, a user conventionally presses or clicks a play button. When the user desires to play a specific portion of the content item, the user may use a seek bar (e.g., via touchscreen or using a mouse) to scroll to a certain portion of the content item. In some instances, the user may click or select a fast-forward or rewind button to navigate to the desired portion of the content item. However, such navigation methods are inaccurate. For example, when the seek bar is used to navigate, the timing numbers update in rapid succession until eventually the user manages to find the portion of the content item they desire. There is a need in the industry for a technical solution to the technical problem of navigating content items in a more sophisticated and technically efficient manner. 
     Accordingly, the disclosed techniques provide methods, systems, and computer-readable media for navigating tags on time-synchronized content items. It should be noted that songs will be described as the primary content items herein, but the techniques apply to any suitable content item. Songs have structures including stanzas, and the stanzas may include various portions: verses, pre-choruses, choruses, hooks, bridges, outros, and the like. Further, the songs may include text, such as lyrics, that is time-synchronized with audio of the song by a cloud-based computing system. For example, each lyric may be timestamped and associated with its corresponding audio such that the lyric is presented lockstep on a user interface of a user&#39;s computing device when a media play plays the audio of the song. In some embodiments, the stanzas may be tagged with a tag that identifies the stanza as being a verse, chorus, outro, etc. 
     Moreover, in some embodiments, the disclosed techniques provide a user interface that enable a user to edit time-synchronized lyrics of a song to add tags to the various lyrics. For example, the user may select a portion of the lyrics and add a tag (# chorus) that indicates that portion of the lyrics at that synchronized time is the chorus. The user may save the tags that are added to the lyrics. When the song is played again, the added tags may appear as graphical user elements on the user interface of a media player playing the song. The graphical user elements representing the tags may include timestamps of when the portion of the song begins and the identifier of the tag (e.g., chorus). If a user selects the graphical user element representing the tag of the chorus, the media player may immediately begin playing the song at the timestamp of the portion of the song including the chorus. Further, as the user uses the seek bar to scan a song, each of the graphical user elements representing the structure of the song may be actuated (e.g., highlighted) at respective times when the tags apply to the portions of the song being played. 
     Such techniques may enhance navigating a song as the song is played and/or to “jump” to a portion of a desired song much more easily than previously allowed. That is, there may be numerous graphical user elements representing tags presented sequentially by timestamp in the user interface including the media player playing a song. For example, one graphical user element representing a tag may include a timestamp (0:15 minutes) and an identity of the tag (e.g., intro), the next graphical user element representing the next graphical user element may include another timestamp (0:30) and an identity of another tag (e.g., verse), yet another graphical user element representing yet another graphical user element may include another timestamp (0:45) and an identity of another tag (e.g., chorus). Upon any of the graphical user elements being selected, the song may begin playing in the media player at the timestamp associated with the tag represented by the selected graphical user element. 
     In some embodiments, the disclosed techniques enable a user to use voice commands with a smart device to ask the smart device to “play the chorus of SONG A”. Upon receiving such a voice command, the smart device may begin playing SONG A at the portion of the song representing the chorus, which was previously tagged by a user and/or a trained machine learning model. The smart device and/or a cloud-based computing system may receive the voice command and process the audio using natural language processing to parse the audio data and determine what words were spoken. The determined words and/or audio data may be compared to data identifying the song and/or the tag requested. If the smart device and/or cloud-based computing system identifies the song and/or the tag requested, the smart device may begin playing the song at the timestamp associated with the tag. Such a technique is a technical solution to enabling a user to navigate songs more efficiently using smart devices at the portion of the songs the users desire without having to use a scanning mechanism (e.g., scroll bar, fast-forward button, rewind button, etc.). 
     In some embodiments, machine learning models may be trained to analyze songs, determine what stanzas are included in the songs, and to tag the various stanzas. The machine learning models may be trained with training data including songs with their lyrics and the lyrics may be labeled with tags. The machine learning models may compare the audio and/or process the lyrics to correlate the audio and/or the lyrics with the tags. Once trained, the machine learning models may receive a new song as input and process its audio and/or lyrics to identify a match with another songs audio and/or lyrics. Based on the match, the machine learning models may be trained to output the corresponding tags for the audio and/or lyrics. The tagged stanzas may be presented to a user via a user interface for the user to review the tagged stanzas. The user may approve, decline, and/or edit the stanzas tagged by the machine learning models. In some embodiments, the machine learning models may be trained to analyze tags that are entered by a user and determine whether the tags are accurate or not. For example, the user may tag a stanza of a song as “chorus” but the machine learning model may be trained to determine the stanza is a “verse” (either based on previous tags, similar lyrics of the same song, similar lyrics of a different song, etc.). In such an instance, the machine learning models may cause a notification to be presented on a user interface that indicates the tag the user entered may be inaccurate. 
     Further, the disclosed techniques enable a user to discover new music more efficiently by allowing the users to skip to the most important parts of a song to determine whether they like the “vibe” of the song. Additionally, such techniques may enable learning a song more quickly because the techniques enable playing a song part by part (e.g., intro, verse, chorus, outro, etc.). As such, the disclosed techniques may save computing resources (e.g., processor, memory, network bandwidth) by enabling a user to use a computing device to just consume desired portions of a song instead of the entire file representing the entire song. That is, the disclosed techniques may provide a very granular mechanism that enables navigating songs more efficiently. 
     Turning now to the figures,  FIG. 1  depicts a system architecture  10  according to some embodiments. The system architecture  10  may include one or more computing devices  12  of one or more users communicatively coupled to a cloud-based computing system  116 . Each of the computing devices  12  and components included in the cloud-based computing system  116  may include one or more processing devices, memory devices, and/or network interface cards. The network interface cards may enable communication via a wireless protocol for transmitting data over short distances, such as Bluetooth, ZigBee, NFC, etc. Additionally, the network interface cards may enable communicating data over long distances, and in one example, the computing devices  12  and the cloud-based computing system  116  may communicate with a network  20 . Network  20  may be a public network (e.g., connected to the Internet via wired (Ethernet) or wireless (WiFi)), a private network (e.g., a local area network (LAN) or wide area network (WAN)), or a combination thereof. Network  20  may also comprise a node or nodes on the Internet of Things (IoT). 
     The computing devices  12  may be any suitable computing device, such as a laptop, tablet, smartphone, or computer. The computing devices  12  may include a display capable of presenting a user interface  160  of an application. The application may be implemented in computer instructions stored on the one or more memory devices of the computing devices  12  and executable by the one or more processing devices of the computing device  12 . The application may present various screens to a user. For example, the user interface  160  may present a media player that enables playing a content item, such as a song. When the user actuates a portion of the user interface  160  to play the content item, the display may present video associated with the content item and/or a speaker may emit audio associated with the content item. Further, the user interface  160  may be configured to present time-synchronized text associated with the content item in a first portion and one or more tags associated with a structure of the content item in a second portion. The tags may correspond to stanzas of a song and may refer to an intro, a verse, a chorus, a bridge, an outro, etc. The user interface  160  may enable a user to edit the time-synchronized text of the content item by assigning tags, modifying tags, deleting tags, etc. Once the tags are saved, during playback of the content item, the user may select one of the tags displayed in the user interface  160  to immediately jump to, skip to, or move the playback of the content item to a timestamp associated with the tag. 
     Such techniques provide for enhanced navigation of content items. Further, the user may use voice commands to trigger the tags to navigate the content items. In some embodiments, trained machine learning models may analyze content items and assign tags. In some embodiments, the trained machine learning models may determine that consecutive portions of the time-synchronized text are labeled with the same tag and may bundle those portions into a group and provide a single tag for the portions. that enable the three-parties (e.g., candidate, referrer, and hiring entity) to perform the functionalities described herein. In some embodiments, the application is a stand-alone application installed and executing on the computing devices  12 ,  13 ,  15 . In some embodiments, the application (e.g., website) executes within another application (e.g., web browser). The computing devices  12  may also include instructions stored on the one or more memory devices that, when executed by the one or more processing devices of the computing devices  12  perform operations of any of the methods described herein. 
     In some embodiments, the cloud-based computing system  116  may include one or more servers  128  that form a distributed computing architecture. The servers  128  may be a rackmount server, a router computer, a personal computer, a portable digital assistant, a mobile phone, a laptop computer, a tablet computer, a camera, a video camera, a netbook, a desktop computer, a media center, any other device capable of functioning as a server, or any combination of the above. Each of the servers  128  may include one or more processing devices, memory devices, data storage, and/or network interface cards. The servers  128  may be in communication with one another via any suitable communication protocol. The servers  128  may execute an artificial intelligence (AI) engine that uses one or more machine learning models  154  to perform at least one of the embodiments disclosed herein. The cloud-based computing system  128  may also include a database  129  that stores data, knowledge, and data structures used to perform various embodiments. For example, the database  129  may store the content items, the time-synchronized text, the tags and their association with the time-synchronized text, user profiles, etc. In some embodiments, the database  129  may be hosted on one or more of the servers  128 . 
     In some embodiments the cloud-based computing system  116  may include a training engine  152  capable of generating the one or more machine learning models  154 . The machine learning models  154  may be trained to analyze content items and to assign tags to various time-synchronized text included in the content items, to determine whether a user has entered an incorrect tag for a time-synchronized text, and the like. The one or more machine learning models  154  may be generated by the training engine  130  and may be implemented in computer instructions executable by one or more processing devices of the training engine  152  and/or the servers  128 . To generate the one or more machine learning models  154 , the training engine  152  may train the one or more machine learning models  154 . 
     The training engine  152  may be a rackmount server, a router computer, a personal computer, a portable digital assistant, a smartphone, a laptop computer, a tablet computer, a netbook, a desktop computer, an Internet of Things (IoT) device, any other desired computing device, or any combination of the above. The training engine  152  may be cloud-based, be a real-time software platform, include privacy software or protocols, and/or include security software or protocols. 
     To generate the one or more machine learning models  154 , the training engine  152  may train the one or more machine learning models  154 . The training engine  152  may use a base data set of content items including their time-synchronized text and labels corresponding to tags of the time-synchronized text. 
     The one or more machine learning models  154  may refer to model artifacts created by the training engine  152  using training data that includes training inputs and corresponding target outputs. The training engine  152  may find patterns in the training data wherein such patterns map the training input to the target output and generate the machine learning models  154  that capture these patterns. For example, the machine learning model may receive a content item, determine a similar content item based on the audio, time-syncrhonized text, video, etc. and determine various tags for the content item based on the similar content item. Although depicted separately from the server  128 , in some embodiments, the training engine  152  may reside on server  128 . Further, in some embodiments, the database  150 , and/or the training engine  152  may reside on the computing devices  12 ,  13 , and/or  15 . 
     As described in more detail below, the one or more machine learning models  154  may comprise, e.g., a single level of linear or non-linear operations (e.g., a support vector machine [SVM]) or the machine learning models  154  may be a deep network, i.e., a machine learning model comprising multiple levels of non-linear operations. Examples of deep networks are neural networks, including generative adversarial networks, convolutional neural networks, recurrent neural networks with one or more hidden layers, and fully connected neural networks (e.g., each neuron may transmit its output signal to the input of the remaining neurons, as well as to itself). For example, the machine learning model may include numerous layers and/or hidden layers that perform calculations (e.g., dot products) using various neurons. 
       FIG. 2  illustrates a user interface  160  including a media player  200  playing a song and presenting lyrics  202  and a selected tag  204  according to certain embodiments of this disclosure. The user interface  160  is presented on the computing device  12  of a user. As depicted, the media player  200  is playing a song titled “Therefore I am”. The lyrics  202  for the song are presented on the user interface  160 . The lyrics may be emphasized lockstep with the audio (e.g., time-synchronized) such that the lyrics are modified when their respective portion of the song is played via audio. As depicted, “I THINK, THEREFORE, I AM” is emphasized in such a manner for the time-synchronized text with the audio of the song. Further, as depicted, the tag  204  is selected, and it includes a tag identity (e.g., “Chorus”) and a timestamp of when the tag for the particular tag identity begins. Also, there are additional tags that are depicted in the diagram. For example, a second tag “0:26 Verse” indicates that if the user desires to hear the verse at the 0:26 mark, the user should select the graphical user element representing that tag. A third tag indicates “0:55 Pre-Chorus”, and selection of that graphical user element on the user interface  160  causes playback of the content item to skip to that timestamp. As depicted, the media player  200  includes graphical user elements to fast-forward, rewind, pause, and/or play content items. Further, the media player  200  includes a seek bar that enables a user to use a touchscreen and/or a mouse to scroll through various portions of the content item. As the user scrolls through the content item, the corresponding graphical user elements associated with the tags may be actuated (e.g., highlighted, emphasized, etc.). The lyrics  202  may be presented in a first portion of the user interface  160  and the tags (e.g.,  204 ) may be concurrently presented in a second portion of the user interface  160 . Such an enhanced user interface may provide a better user experience and enhance a user&#39;s enjoyment of using the computing device while consuming the content item. 
       FIG. 3  illustrates a user interface  160  including a media player  200  playing a song and presenting lyrics  202  and another selected tag  300  according to certain embodiments of this disclosure. As depicted, the selected tag  300  represents the timestamp of  0 : 26  and has a tag identity of “Verse”. After the user selected the tag  300 , the media player began playback of the content item at 0:26 and emphasized the time-synchronized text of “I&#39;M NOT YOUR FRIEND OR ANYTHING”. As such, the user interface  160  and the media player  200  dynamically adjust based on which tag is selected. 
       FIG. 4  illustrates a user interface  160  including a media player  200  playing a song and presenting lyrics  202  and tags during scrolling according to certain embodiments of this disclosure. As depicted, a seek bar  400  may be presented on the user interface  160 . A user may use a touchscreen, mouse, keyboard, or any suitable input peripheral to use the seek bar. As the user actuates the seek bar to scroll forward or backward in the content item, the various tags  402  are actuated (e.g., emphasized, highlighted, etc.) when their corresponding time-synchronized text is presented on the user interface  160 . 
       FIG. 5  illustrates a user interface  160  including a media player  200  during an edit mode where a user edits tags  500  for lyrics  202  according to certain embodiments of this disclosure. To enter this mode, the user may select a graphical user element titled “Edit Lyrics” or has any suitable title. The user interface  160  may be presented via an application installed on the user&#39;s computing device  12  and/or a web browser executing on the user&#39;s computing device  12 . The user interface  160  may enable direct entry of tags to associated time-synchronized text. For example, as depicted, the time-synchronized text “I think, therefore, I am” is tagged with “# chorus”, and the time-synchronized text “I&#39;m not your friend or anything” is tagged with “# verse”. The user may select graphical user element  502  (e.g. button) to save the tags with the time-synchronized text to the file representing the content item at the cloud-based computing system  116 . Once these tags are saved to the file representing the content item in the cloud-based computing system  116 , the tags may appear as graphical elements on the user interface  160  during playback of the content item and may enable navigating to the portion of the content item associated with the tags. For example, the time-synchronized text and the tags may be concurrently presented on the user interface  160  during playback of the content item using the media player. 
       FIG. 6  illustrates a user  600  instructing a smart device (e.g., computing device  12 ) to play a content item at a particular tag according to certain embodiments of this disclosure. As depicted, the user  600  may say a voice command to the smart device. The smart device may receive the voice command and process the voice command to being playing the content item at the tag identified by the user  600 . Using enhanced voice commands may provide an enriched user experience of computing devices. Further, the tags may be granularly tailored in such a way that the user may say “play the song with the guitar solo by Slash”, etc. That is, the tags may not only enable tagging structures of content item but tagging any time-synchronized data based on any suitable attribute. 
       FIG. 7  illustrates an example of a method  700  for generating tags for time-synchronized text pertaining to content items according to certain embodiments of this disclosure. The method  700  may be performed by processing logic that may include hardware (circuitry, dedicated logic, etc.), software, or a combination of both. The method  700  and/or each of their individual functions, subroutines, or operations may be performed by one or more processors of a computing device (e.g., any component (server  128 , training engine  152 , machine learning models  154 , etc.) of cloud-based computing system  116  and/or computing device  12  of  FIG. 1 ) implementing the method  700 . The method  700  may be implemented as computer instructions stored on a memory device and executable by the one or more processors. In certain implementations, the method  700  may be performed by a single processing thread. Alternatively, the method  700  may be performed by two or more processing threads, each thread implementing one or more individual functions, routines, subroutines, or operations of the methods. 
     At block  702 , the processing device may present, via the user interface  160  at the client computing device  12 , time-synchronized text pertaining to the content item (e.g., song). The cloud-based computing system  116  may have synchronized the text with the audio of the content item prior to the computing device  12  receiving the content item. 
     At  704 , the processing device may receive an input of a tag for the time-synchronized text of the content item. The tag may be entered via the user interface  160  by a user entering text having a particular syntax (e.g., # chorus).
