DESCRIPTION OF EMBODIMENTS
Some embodiments in this disclosure relate to a method and/or system that may transcribe audio communication sessions. In some embodiments, a mobile device, for example a smart phone, may begin a communication session over a cellular network. A user of the mobile device may be hearing-impaired. As a result, the user may not be able to fully understand audio received during the communication session. The audio may be voice data generated by another device participating in the communication session. In these and other embodiments, the audio received over the cellular network communication session may be transferred to an audio output device over a second wireless network. For example, the audio output device may be a Bluetooth headset and the second wireless network may be a Bluetooth network.
The audio output device may be configured to multiplex the received audio. The multiplexed received audio may be sent to a speaker of the audio output device to be broadcast to the user. The multiplexed received audio may also be encoded for transmission over a third wireless network to a transcription system. In these and other embodiments, the transcription system may be configured to transcribe the audio and send a transcript of the audio to the mobile device for presentation to the user. The transcript may assist the user in understanding the audio and better participate in the communication session.
In some embodiments, the systems and/or methods described in this disclosure may help to enable the transcription of audio received at a mobile device or other devices during a communication session. In other settings, audio received at devices during a communication session of a cellular network may not be easily captured by an application running on the device. For example, the audio from a phone call on a cellular network using a smart phone or other cellular phone is typically isolated from third party applications that are executed by the smart phone. As a result, the audio from the phone call may not be easily, or in some circumstances may not be able to be, multiplexed and transferred to a transcription system to generate a transcript to assist the hearing impaired during the phone call. The systems and/or methods described in this disclosure may assist in enabling the capture and generation of a transcript of audio from a phone call on a cellular network using a cellular enabled device. Thus, the systems and/or methods provide at least a technical solution to a technical problem associated with the design of cellular enabled devices in the technology of telecommunications.
Turning to the figures, FIG. 1 illustrates an example system 100 configured to provide transcripts of an audio communication session. The system 100 may be arranged in accordance with at least one embodiment described in the present disclosure. The system 100 may include a network 102, a mobile device 110, an audio output device 120, an access point 130, a transcription system 140, and a device 160.

In the communication session, data, such as audio data may be exchanged between the device 160 and the mobile device 110 by way of the network 102 and the first wireless network 150. In these and other embodiments, the network 102 that communicatively couples the device 160 and the access point 130 may be the same as or different than the first wireless network 150.
In some embodiments, the transcription system 140 may include any configuration of hardware, such as processors, servers, and databases that are networked together and configured to generate transcripts by transcribing audio data received over the network 102. For example, the transcription system 140 may include multiple computing systems, such as multiple servers that each include memory and at least one processor, which are networked together and configured to perform operations as described in this disclosure, among other operations. In some embodiments, the transcription system 140 may include computer-readable-instructions that are configured to be executed by the transcription system 140 to perform operations described in this disclosure.
In some embodiments, the transcription system 140 may be configured to transcribe audio data received from the mobile device 110 to generate transcripts of the audio data. In some embodiments, the audio data may be data received by the mobile device 110 over the first wireless network 150, such as from the device 160. Alternatively or additionally, the audio data may be generated by the audio output device 120 and may be received by the mobile device 110 from the audio output device 120 over the second wireless network 152 or the third wireless network 154.
In some embodiments, the transcription system 140 may be configured to provide the generated transcripts to the mobile device 110 over the network 102 and the first wireless network 150. In these and other embodiments, the mobile device 110 may be configured to display the generated transcripts on a display of the mobile device 110.
An example of the operation of the system 100 follows. A communication session may be established between the mobile device 110 and the device 160 by way of the access point 130 using the first wireless network 150 and the network 102. For example, the mobile device 110 may call the device 160 to establish the communication session. Alternatively or additionally, the device 160 may call the mobile device 110 to establish the communication session.
The mobile device 110 may be used by a user that is hearing-impaired. As used in the present disclosure, a “hearing-impaired user” may refer to a person with diminished hearing capabilities. Hearing-impaired users often have some level of hearing ability that has usually diminished over a period of time such that the hearing-impaired user can communicate by speaking, but that the hearing-impaired user often struggles in hearing and/or understanding others.
During the communication session, the mobile device 110 may receive audio data over the first wireless network 150 from the access point 130. The audio data may originate from the device 160. For example, the audio data may be based on a voice signal from a user of the device 160. For example, the voice signal may be words spoken by the user of the device 160 during a conversation with the user of the mobile device 110 during the communication session.
The mobile device 110 may transmit the audio data over the second wireless network 152 to the audio output device 120. The audio output device 120 may multiplex the audio data to output the audio data by way of the speaker included in the audio output device 120 and to transmit the audio data over the third wireless network 154 to the mobile device 110.
The mobile device 110 may receive the audio data from the audio output device 120 by way of the third wireless network 154. The mobile device 110, by way of an application executed by the mobile device 110 and associated with the transcription system 140, may send the audio data received from the audio output device 120 over the first wireless network 150 to the transcription system 140. The transcription system 140 may transcribe the audio data to generate a transcript of the audio data. In some embodiments, to transcribe the audio data, a call assistant may listen to the audio data and “revoice” the words of the audio data to a speech recognition computer program tuned to the voice of the call assistant. In some embodiments, the transcript may be generated by the speech recognition computer.
The transcript of the audio data may be provided over the first wireless network 150 to the mobile device 110. In some embodiments, the mobile device 110, by way of the application associated with the transcription system 140 and an electronic display, may display the transcript while the hearing-impaired user carries on a normal conversation with a user of the device 160 during the communication session. The transcript may allow the hearing-impaired user to supplement the audio data received from the device 160 and confirm his or her understanding of the words spoken by the user of the device 160.
The system 100 may be configured to provide the transcript of the audio data in substantially real-time or real-time. For example, the transcript of the audio data may be provided to the mobile device 110 in less than 2, 3, 5, or 10 seconds after the audio data is presented to the user of the mobile device 110 by the audio output device 120.
As described, the system 100 may be configured to provide transcripts of audio data received by the mobile device 110. As discussed previously, in some circumstances, the mobile device 110 may be configured such that an application associated with the transcription system 140 executed by the mobile device 110 may be unable to obtain the audio data. As a result, the mobile device 110 may be unable to provide the audio data to the transcription system 140 for a transcript of the audio data. The system 100 may provide a manner for a transcript to be provided to the mobile device 110.
In some embodiments, the device 160 may be associated with a hearing impaired user and may be in communication with the transcription system 140. In these and other embodiments, the audio output device 120 may capture words spoken by the user of the mobile device 110 as audio data. The audio output device 120 may send the audio data to the mobile device 110 over the second wireless network 152 and/or the third wireless network 154. The audio data transmitted over the second wireless network 152 may be sent to the device 160 as audio data for presentation to the user of the device 160 as normal audio data. The mobile device 110, by way of an application associated with the transcription system 140, may transmit the audio data received over the second wireless network 152 and/or third wireless network 154 to the transcription system 140 with an indication that the transcript be provided to the device 160. The transcription system 140 may transcribe the audio data and provide the transcript to the device 160. The device 160 may present the transcript on a display of the device 160 for the hearing-impaired user of the device 160. Alternatively or additionally, the device 160 may be associated with an audio output device 120 and may receive transcripts of audio data originating from the mobile device 110 in a manner analogous to how the mobile device 110 receives transcripts.
Modifications, additions, or omissions may be made to the system 100 without departing from the scope of the present disclosure. For example, in some embodiments, the system 100 may include additional devices similar to the mobile device 110. Alternatively or additionally, the device 160 may be paired with another device that is similar to the audio output device 120. Alternatively or additionally, one or more of the communication couplings between the mobile device 110 and the audio output device 120 may be a wired connection. In these and other embodiments, the second wireless network 152 may be a wired network. Alternatively or additionally, the third wireless network 154 may be a wired network.
In some embodiments, the mobile device 110 and the audio output device 120 may be communicatively coupled by one wireless or wired network. In these and other embodiments, audio data may be received by the audio output device 120, multiplexed, and sent back to the mobile device 110 using the same wireless or wired network.
FIG. 2 illustrates example operations 200 in a system configured to provide transcriptions of an audio communication session. The operations 200 may be arranged in accordance with at least one embodiment described in the present disclosure. The operations 200 illustrated are not exhaustive but are merely representative of operations 200 that may occur. Furthermore, one operation as illustrated may represent one or more communications, operations, and/or data exchanges. Alternatively or additionally, the ordering of the operations 200 may differ than that illustrated in FIG. 2.
The operations 200 may occur between a mobile device 210, an audio output device 220, and a transcription system 240. In some embodiments, the mobile device 210, the audio output device 220, and the transcription system 240 may be analogous to the mobile device 110, the audio output device 120, and the transcription system 140, respectively, of FIG. 1. Accordingly, no further explanation is provided with respect thereto.
In some embodiments, the operations 200 may be an example of communications and interactions between the mobile device 210, the audio output device 220, and the transcription system 240 that may occur over one or more networks. For example, the mobile device 210 may be configured to exchange data over three different wireless networks, a cellular network, a Bluetooth network, and a WIFI network. In these and other embodiments, the mobile device 210 and the audio output device 220 may be configured to exchange data over two different wireless networks, a Bluetooth network and a WIFI network. Lines representing operations 200 that may occur or partially occur over a wireless network are represented differently depending on the wireless network used for those operations 200. For example, in FIG. 2, a solid line may represent an operation, such as a communication, over a Bluetooth network. A dashed line may represent an operation, such as a communication, over a WIFI network. A dash-dot line may represent an operation, such as a communication, over a cellular network. Each of these networks may have different protocols, operating frequencies, and/or data packet configurations.
The operations 200 may include obtaining 250 first audio data at the mobile device 210 over a cellular network. The first audio data may be obtained from another device. In some embodiments, the first audio data may be based on voice signals received at the other device during a communication session between the mobile device 210 and the other device.
A Bluetooth wireless connection may be established 252 between the mobile device 210 and the audio output device 220. In these and other embodiments, the mobile device 210 and the audio output device 220 may exchange one or more packets of data following Bluetooth protocols to establish the Bluetooth wireless connection. In these and other embodiments, the Bluetooth audio connection may be established to stream audio data from the mobile device 210 to the audio output device 220.
In some embodiments, the audio data streamed between the mobile device 210 and the audio output device 220 may be streamed using an advanced audio distribution profile (A2DP).

In these and other embodiments, the WiFi audio connection may be established to stream audio data from the mobile device 210 to the audio output device 220. In some embodiments, the WiFi wireless connection may be established using an access point of a WiFi wireless network. In these and other embodiments, the access point may act as a router to route data communications between the mobile device 210 and the audio output device 220.
The audio output device 220 may transmit and the mobile device 210 may receive 258, the second audio data stream over the WiFi network. In these and other embodiments, the audio output device 220 may encode the second audio data stream based on the WiFi protocol to transmit the audio data to the mobile device 210 over the WiFi network. After receiving the audio data, the mobile device 210 may decode the second audio data stream and prepare the second audio data stream for transmission to the transcription system 240.
A network connection may be established 260 between the mobile device 210 and the transcription system 240. In these and other embodiments, the mobile device 210 and the transcription system 240 may exchange one or more packets of data to establish a connection between the mobile device 210 and the transcription system 240. For example, an application associated with the transcription system 240 may be executed by the mobile device 210. The application may include authentication protocols to establish a network connection with a server of the transcription system 240 to allow for the exchange of information between the mobile device 210 and the transcription system 240.
The mobile device 210 may transmit and the transcription system 240 may receive 262 the second audio data stream over the cellular network. In these and other embodiments, the transcription system 240 may decode the second audio data stream from the cellular network, may obtain the data packets, and may create a transcript 267 using the data packets. The transcription system 240 may transmit and the mobile device 210 may receive 268 the transcript over the cellular network.
The audio output device 220 may further generate second audio data. For example, the second audio data may be generated based on voice signals captured by the audio output device 220 from a user of the mobile device 210 and the audio output device 220.

The mobile device 210 may decode the second audio data, may encode the second audio data based on the cellular network protocols, and may transmit the second audio data 266 over the cellular network. The second audio data may be part of a communication session between the mobile device 210 and the other device.
The mobile device 210 may present the transcript 270 to the user of the mobile device 210. For example, the mobile device 210 may display the transcript on an electronic display of the mobile device 210. By displaying the transcript, a user of the mobile device 210 may read and hear the first audio data.
The operations 200 may continue. For example, the operations 200 may include obtaining 272 third audio data at the mobile device 210 over the cellular network. The third audio data may be obtained from the other device. The mobile device 210 may transmit and the audio output device 220 may receive 274, the third audio data from the cellular network.
After receiving the third audio data, the audio output device 220 may decode the third audio data and may multiplex the third audio data into third and fourth audio data streams. The third audio data stream may be output 276 at a speaker. The fourth audio data stream may be transmitted back to the mobile device 210 by the audio output device 220 over the WiFi network.
Modifications, additions, or omissions may be made to the operations 200 without departing from the scope of the present disclosure. For example, in some embodiments, the order of the operations 200 may change. For example, the establishment of the Bluetooth network connection 252, the WiFi network connection 256, and the network connection 260 may occur before the first audio data is obtained 250. Alternatively or additionally, the establishment of network connections may occur during other times. Furthermore, the operations 200 may not occur in a linear fashion as illustrated, but may overlap in time such that they occur at substantially the same time. For example, some of the operations, such as the transmitting and receiving of the second audio data between the audio output device 220 and the mobile device 210 may occur while the first audio data is transmitted to the transcription system 240 from the mobile device 210.

As indicated above, the embodiments described herein may include the use of a special purpose or general purpose computer (e.g., the processor 510 of FIG. 5) including various computer hardware or software modules, as discussed in greater detail below. Further, as indicated above, embodiments described herein may be implemented using computer-readable media (e.g., the memory 512 or data storage 514 of FIG. 5) for carrying or having computer-executable instructions or data structures stored thereon.
In some embodiments, the different components, modules, engines, and services described herein may be implemented as objects or processes that execute on a computing system (e.g., as separate threads). While some of the systems and methods described herein are generally described as being implemented in software (stored on and/or executed by general purpose hardware), specific hardware implementations or a combination of software and specific hardware implementations are also possible and contemplated.
In accordance with common practice, the various features illustrated in the drawings may not be drawn to scale. The illustrations presented in the present disclosure are not meant to be actual views of any particular apparatus (e.g., device, system, etc.) or method, but are merely idealized representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or all operations of a particular method.
Terms used herein and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.).
Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.
In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” or “one or more of A, B, and C, etc.” is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc. For example, the use of the term “and/or” is intended to be construed in this manner.
Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” should be understood to include the possibilities of “A” or “B” or “A and B.”
However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.
Additionally, the use of the terms “first,” “second,” “third,” etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms “first,” “second,” “third,” etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms “first,” “second,” “third,” etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms first,” “second,” “third,” etc., connote a specific number of elements, these terms should not be understood to connote a specific number of elements. For example, a first widget may be described as having a first side and a second widget may be described as having a second side. The use of the term “second side” with respect to the second widget may be to distinguish such side of the second widget from the “first side” of the first widget and not to connote that the second widget has two sides.
All examples and conditional language recited herein are intended for pedagogical objects to aid the reader in understanding the invention and the concepts contributed by the inventor to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. Although embodiments of the present disclosure have been described in detail, it should be understood that the various changes, substitutions, and alterations could be made hereto without departing from the spirit and scope of the present disclosure.
