Audio feedback for user call status awareness

1. A method performed by a wearable audio output device worn by a user, including a microphone, comprising:

participating in a teleconference with one or more remote participants via a user device, wherein the user and the one or more remote participants share an audio stream supported by the teleconference;

determining a state of the user selected from a set of user states comprising at least:

a listen mode wherein the microphone is muted so that speech of the user and environmental noise around the user are not heard by the remote participants,

a whisper mode wherein the microphone is unmuted and the speech of the user and the environmental noise around the user are capable of being heard by a subset of the remote participants, and

a talk mode wherein the microphone is unmuted and the speech of the user and the environmental noise are capable of being heard by all of the remote participants; and

providing audio feedback to the user based on the determined state of the user with respect to the teleconference, wherein providing the audio feedback comprises adding or removing at least one of reverberation or spatialization.

2. The method of claim 1 , wherein providing the audio feedback comprises:

adding the reverberation to the audio stream when the user is in the listen mode; and

removing the reverberation when the user subsequently changes from the listen mode to the talk mode.

3. The method of claim 1 , wherein providing the audio feedback comprises:

spatializing the audio stream when the user is in the listen mode; and

removing the spatializing when the user subsequently changes from the listen mode to the talk mode.

4. The method of claim 1 , wherein providing the audio feedback comprises:

simultaneously outputting an audio notification and the audio stream when the user switches between the listen mode and the talk mode.

5. The method of claim 4 , wherein:

the audio notification is spatialized in a first manner to indicate switching from the listen mode to the talk mode, and

the audio notification is spatialized in a second manner to indicate switching from the talk mode to the listen mode.

6. The method of claim 1 , wherein adding or removing at least one of the reverberation or the spatialization further comprises:

adjusting a feature of the audio stream to reduce an intelligibility of the audio stream when the user is in the listen mode; and

adjusting the feature of the audio stream to increase the intelligibility of the audio stream when the user subsequently changes from the listen mode to the talk mode.

7. The method of claim 1 , wherein providing the audio feedback comprises:

outputting the audio stream to one ear of the user when the user is in the whisper mode, and

outputting the audio stream to both ears of the user when the user is in the talk mode.

8. The method of claim 1 , further comprising:

simultaneously outputting a second audio stream with the audio stream supported by the teleconference,

wherein providing the audio feedback comprises adjusting the second audio stream based on the state of the user.

9. The method of claim 8 , wherein adjusting the second audio stream comprises:

reducing a volume of the second audio stream from a first volume to a second volume when the microphone is unmuted; and

increasing the volume from the second volume back to the first volume when the microphone is subsequently muted.

10. The method of claim 1 , wherein providing the audio feedback comprises:

altering the audio stream based on the state of the user;

outputting the altered audio stream to the user to indicate the state of the user;

after outputting the altered audio stream, determining a change in the state of the user;

re-altering the audio stream based on the change in the state of the user; and

outputting the re-altered audio stream to the user to indicate the change in the state of the user.

11. The method of claim 1 , wherein the wearable audio output device does not provide a visual indication of the state.

12. A wearable audio output device comprising:

a microphone; and

at least one processor coupled to the microphone, the at least one processor configured to:

participate in a teleconference with one or more remote participants via a user device, wherein a user wearing the wearable audio output device and the one or more remote participants share an audio stream supported by the teleconference;

determine a state of the user selected from a set of user states comprising at least:

a listen mode wherein the microphone is muted so that speech of the user and environmental noise around the user are not heard by the remote participants,

a whisper mode wherein the microphone is unmuted and the speech of the user and the environmental noise around the user are capable of being heard by a subset of the remote participants, and

a talk mode wherein the microphone is unmuted and the speech of the user and the environmental noise are capable of being heard by all of the remote participants; and

provide audio feedback to the user based on the determined state of the user with respect to the teleconference, wherein providing the audio feedback comprises adding or removing at least one of reverberation or spatialization.

13. The wearable audio output device of claim 12 , wherein the at least one processor provides the audio feedback by:

adding the reverberation to the audio stream when the user is in the listen mode; and

removing the reverberation when the user subsequently changes from the listen mode to the talk mode.

14. The wearable audio output device of claim 13 , wherein the at least one processor provides the audio feedback by:

spatializing the audio stream when the user is in the listen mode; and

removing the spatializing when the user subsequently changes from the listen mode to the talk mode.

15. The wearable audio output device of claim 12 , wherein the wearable audio output device does not provide a visual indication of the state.

16. The wearable audio output device of claim 12 , further comprising:

a mute function for muting and unmuting both speech of the user and environmental noise around the user.

17. The wearable audio output device of claim 16 , wherein the mute function is activated by one of a capacitive user interface on the wearable audio output device or a hardware button on the wearable audio output device.

18. A wearable audio output device comprising:

a microphone; and

at least one processor coupled to the microphone, the at least one processor configured to:

participate in a teleconference with one or more remote participants via a user device, wherein a user wearing the wearable audio output device and the one or more remote participants share an audio stream supported by the teleconference;

determine a state of the user selected from a set of user states comprising at least:

a listen mode wherein the microphone is muted so that speech of the user and environmental noise around the user are not heard by the remote participants,

a whisper mode wherein the microphone is unmuted and the speech of the user and the environmental noise around the user are capable of being heard by a subset of the remote participants, and

a talk mode wherein the microphone is unmuted and the speech of the user and the environmental noise are capable of being heard by all of the remote participants;

alter the audio stream based on the determined state of the user, wherein altering the audio stream comprises adding or removing at least one of reverberation or spatialization; and

output the altered audio stream to indicate the state of the user.

19. The wearable audio output device of claim 18 , wherein the at least one processor is configured to alter the audio stream by one of:

adding the reverberation to the audio stream or spatializing the audio stream when the user is in the listen mode.
