Abstract

An example operation may include one or more of generating a local audio file comprising audio captured of a user participating in a teleconference, receiving one or more other local audio files of the teleconference captured by one or more other audio devices that participated in the teleconference, determining a synchronized playback order for audio portions of the generated local audio file and audio portions of the one or more received local audio files based on timing information included in the generated local audio file and the received timing information, and outputting a playback of the audio portions of the generated local audio file and the detected audio portions of the one or more received local audio files synchronized together based on the determined synchronized playback order.

Claims

1. A computing system, comprising:

a processor configured to generate an audio file comprising audio captured via an audio device by an agent that prevents recording of non-participants during a teleconference; and

a network interface configured to receive one or more other audio files of the teleconference captured by one or more other audio devices that participated in the teleconference, each received audio file comprising detected audio portions captured by other respective agents that prevent recording of non-participants during the teleconference;

wherein the processor is configured to output a playback of the audio captured and the detected audio portions.

2. The computing system of claim 1, wherein the one or more audio files are received from a host server, and each received audio file comprises a user identification associated with an audio device that generated the audio file, a conference identification, timing information, and an audio recording captured by the audio device during the teleconference.

3. The computing system of claim 1, wherein the one or more audio files comprise a plurality of audio files corresponding to a plurality of other users that participated in the teleconference and that consented to sharing their audio file with other users of the teleconference.

4. The computing system of claim 3, wherein the processor is further configured to selectively mute a user from among the plurality of other users that participated in the teleconference by preventing playback of a corresponding audio file of the selected user, in response to receiving a mute request identifying the user.

5. The computing system of claim 3, wherein the generated audio file is captured of a user that did not consent to sharing their audio file with other users of the teleconference and is not shared with the plurality of other users that participated in the teleconference.

6. The computing system of claim 1, wherein the network interface is further configured to receive a timestamp from a host server which is transmitted to all user devices that participate in the teleconference, and the processor is configured to generate the audio file based on the timestamp received.

7. The computing system of claim 1, wherein the network interface is further configured to receive a combined text file including speech from the one or more audios files which have been converted to text and synchronized by a host server.

8. The computing system of claim 1, wherein the processor, via the agent, is configured to recognize and record sound of the user and not record sound of other users during the teleconference when generating the audio file such that a clarity of speech provided by the user of the audio device is more recognizable.

9. The computing system of claim 1, wherein the processor, via the agent, prevents recording of non-participants by recognizing audio of a local participant and filtering out remaining audio.

10. A computer-implemented method, comprising:

generating an audio file comprising audio captured via an audio device by an agent that prevents recording of non-participants during a teleconference;

receiving one or more other audio files of the teleconference captured by one or more other audio devices that participated in the teleconference, each received audio file comprising detected audio portions captured by other respective agents that prevent recording of non-participants during the teleconference; and

outputting a playback of the audio captured and the detected audio portions.

11. The computer-implemented method of claim 10, wherein the one or more audio files are received from a host server, and each received audio file comprises a user identification associated with an audio device that generated the audio file, a conference identification, timing information, and an audio recording captured by the audio device during the teleconference.

12. The computer-implemented method of claim 10, wherein the one or more audio files comprise a plurality of audio files corresponding to a plurality of other users that participated in the teleconference and that consented to sharing their audio file with other users of the teleconference.

13. The computer-implemented method of claim 12, further comprising selectively muting a user from among the plurality of other users that participated in the teleconference by preventing playback of a corresponding audio file of the selected user, in response to receiving a mute request identifying the user.

14. The computer-implemented method of claim 12, wherein the generated audio file is captured of a user that did not consent to sharing their audio file with other users of the teleconference and is not shared with the plurality of other users that participated in the teleconference.

15. The computer-implemented method of claim 10, further comprising receiving a timestamp from a host server which is transmitted to all user devices that participate in the teleconference, and generating the audio file based on the timestamp received.

16. The computer-implemented method of claim 10, further comprising receiving a combined text file including speech from the one or more audios files which have been converted to text and synchronized by a host server.

17. The computer-implemented method of claim 10, wherein the generating, via the agent, comprises recognizing and recording sound of the user while not recording sound of other users during the teleconference when generating the audio file such that a clarity of speech provided by the user of the audio device is more recognizable.

18. A non-transitory computer readable medium having stored therein program instructions that when executed cause a computer to perform a method comprising:

generating an audio file comprising audio captured via an audio device by an agent that prevents recording of non-participants during a teleconference;

receiving one or more other audio files of the teleconference captured by one or more other audio devices that participated in the teleconference, each received audio file comprising detected audio portions captured by other respective agents that prevent recording of non-participants during the teleconference; and

outputting a playback of the audio captured and the detected audio portions.

19. The non-transitory computer readable medium of claim 18, wherein the one or more audio files are received from a host server, and each received audio file comprises a user identification associated with an audio device that generated the audio file, a conference identification, timing information, and an audio recording captured by the audio device during the teleconference.

20. The non-transitory computer readable medium of claim 18, wherein the one or more audio files comprise a plurality of audio files corresponding to a plurality of other users that participated in the teleconference and that consented to sharing their audio file with other users of the teleconference.

21. The non-transitory computer readable medium of claim 20, wherein the method further comprises selectively muting a user from among the plurality of other users that participated in the teleconference by preventing playback of a corresponding audio file of the selected user, in response to receiving a mute request identifying the user.
