Abstract

A client application associated with a communications system may connect to a video conference. During the video conference, a decrease in a quality associated with an audio output generated by the communications system may be detected. In response to detecting that the quality associated with the audio output has decreased, a change to the communications system may be determined to increase the quality associated with the audio output. The change may be applied to the communications system to increase the quality of further audio output generated by the communications system during the video conference.

Claims (59)

1. A method, comprising:

detecting that a network latency meets a threshold;

detecting, via a camera, that a participant has moved a threshold distance away from the camera;

determining that a quality associated with an audio output has decreased during a video conference based on the detection that the network latency meets the threshold and the detection that the participant has moved the threshold distance away from the camera, wherein the audio output is generated by a communications system associated with a client application connected to the video conference, and wherein the communications system includes a first microphone and a second microphone that generates the audio output;

determining a change to the communications system to increase the quality associated with the audio output; and

applying the change to the communications system.

2. The method of claim 1 , further comprising:

displaying a message indicating the change to a user interface associated with the client application.

3. The method of claim 1 , wherein the communications system further comprises a speaker, the method further comprising:

playing a message indicating the change via a speaker.

4. The method of claim 1 , further comprising:

providing an alert to a participant associated with the client application; and

applying the change after providing the alert.

5. The method of claim 1 , further comprising:

applying the change to the communications system without providing an alert to a participant associated with the client application.

6. The method of claim 1 , wherein the change comprises:

adjusting a gain associated with the first microphone or the second microphone.

7. The method of claim 1 , wherein the change comprises:

adjusting a first gain associated with the first microphone; and

adjusting a second gain associated with the second microphone.

8. The method of claim 1 , wherein the change comprises:

switching from the first microphone to the second microphone.

9. The method of claim 1 , wherein the change comprises:

measuring the audio output generated by the first microphone and the audio output generated by the second microphone; and

selecting between the first microphone and the second microphone based on the measuring.

10. The method of claim 1 , wherein the change includes pausing the audio output.

11. The method of claim 1 , wherein the client application is a first client application, and further comprising:

detecting, by the first client application, that the quality associated with the audio output has decreased by receiving an indication from a second client application connected to the video conference.

12. The method of claim 1 , wherein the client application is a first client application, and further comprising:

displaying a prompt to a user interface associated with a second client application connected to the video conference, wherein the prompt permits a selection of a participant associated with the first client application; and

sending an indication from the second client application to the first client application based on the selection, wherein the indication permits the first client application to detect that the quality associated with the audio output has decreased.

13. The method of claim 1 , further comprising:

detecting, by the client application, that the quality associated with the audio output has decreased by measuring the audio output.

14. The method of claim 1 , wherein the change comprises:

using a machine learning model to select between the first and second microphones.

15. An apparatus, comprising:

a communications system including a first microphone and a second microphone configured to generate audio output and a camera configured to generate image data;

a camera configured to detect that a participant has moved a threshold distance away from the camera;

a memory; and

a processor configured to execute instructions stored in the memory to:

connect to a video conference;

detect that a network latency meets a threshold;

determine that a quality associated with the audio output has decreased during the video conference based on the detection that the network latency meets a threshold and a detection that the participant has moved the threshold distance away from the camera, wherein the audio output is generated by the communications system associated with a client application connected to the video conference;

determine a change to the communications system to increase the quality associated with the audio output; and

apply the change to the communications system.

16. The apparatus of claim 15 , further comprising:

a user interface, wherein the instructions include instructions to display a message indicating the change to the user interface.

17. The apparatus of claim 15 , wherein the instructions include instructions to:

select between the first microphone and the second microphone based on an orientation direction.

18. A non-transitory computer readable medium storing instructions operable to cause one or more processors to perform operations comprising:

detecting that a network latency meets a threshold;

detecting, via a camera, that a participant has moved a threshold distance away from the camera;

determining that a quality associated with an audio output has decreased during a video conference based on the detection that the network latency meets the threshold and the detection that the participant has moved the threshold distance away from the camera, wherein the audio output is generated by a communications system associated with a client application connected to the video conference, and wherein the communications system includes a first microphone and a second microphone that generates the audio output;

determining a change to the communications system to increase the quality associated with the audio output; and

applying the change to the communications system.

19. The non-transitory computer readable medium storing instructions of claim 18 , the operations further comprising:

displaying a message indicating the change to a user interface associated with the client application.

20. The non-transitory computer readable medium storing instructions of claim 18 , the operations further comprising:

adjusting a gain of a first microphone or a second microphone based on an orientation direction of a participant.
