Private audio communication in a conference call

1. A computer-implemented method, comprising:

receiving a mute request from a first device of a first participant in a conference call;

muting a first audio output from the first device to the conference call;

capturing an audio from the first participant using a first microphone of the first device, wherein the muted first audio output prevents the captured audio from being heard in the conference call; and

transmitting the captured audio to a second participant in the conference call over a private communication channel.

2. The computer-implemented method of claim 1 , wherein the transmitted captured audio is playable to the second participant without notifying other participants in the conference call.

3. The computer-implemented method of claim 1 , further comprising:

determining the second participant for receiving the transmitted captured audio based on a destination input from the first participant.

4. The computer-implemented method of claim 1 , further comprising:

detecting the second participant using a headset in the conference call; and

playing the transmitted captured audio using the headset of the second participant without notifying other participants in the conference call.

5. The computer-implemented method of claim 1 , further comprising:

detecting the second participant using a second device associated with a speaker system in the conference call;

muting a second audio output from the second device to the conference call, wherein the muted second audio output prevents other participants in the conference call from hearing any audio from the speaker system captured by a second microphone associated with the second device; and

playing the transmitted captured audio using the speaker system of the second participant.

6. The computer-implemented method of claim 1 , wherein the conference call further comprises a conference communication channel and the private communication channel in a same virtual meeting room, wherein the conference communication channel enables communication between all participants in the virtual meeting room, and wherein the private communication channel enables communication between the first participant and the second participant in the virtual meeting room, without notifying other participants in the virtual meeting room.

7. The computer-implemented method of claim 1 , wherein the private communication channel is dynamically established as a temporary communication channel for a duration of completing the transmitted captured audio to the second participant.

8. A computer system for private audio communication in a conference call, comprising:

one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage media, and program instructions stored on at least one of the one or more computer-readable tangible storage media for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:

receiving a mute request from a first device of a first participant in a conference call;

muting a first audio output from the first device to the conference call;

capturing an audio from the first participant using a first microphone of the first device, wherein the muted first audio output prevents the captured audio from being heard in the conference call; and

transmitting the captured audio to a second participant in the conference call over a private communication channel.

9. The computer system of claim 8 , wherein the transmitted captured audio is playable to the second participant without notifying other participants in the conference call.

10. The computer system of claim 8 , further comprising:

determining the second participant for receiving the transmitted captured audio based on a destination input from the first participant.

11. The computer system of claim 8 , further comprising:

detecting the second participant using a headset in the conference call; and

playing the transmitted captured audio using the headset of the second participant without notifying other participants in the conference call.

12. The computer system of claim 8 , further comprising:

detecting the second participant using a second device associated with a speaker system in the conference call;

muting a second audio output from the second device to the conference call, wherein the muted second audio output prevents other participants in the conference call from hearing any audio from the speaker system captured by a second microphone associated with the second device; and

playing the transmitted captured audio using the speaker system of the second participant.

13. The computer system of claim 8 , wherein the conference call further comprises a conference communication channel and the private communication channel in a same virtual meeting room, wherein the conference communication channel enables communication between all participants in the virtual meeting room, and wherein the private communication channel enables communication between the first participant and the second participant in the virtual meeting room, without notifying other participants in the virtual meeting room.

14. The computer system of claim 8 , wherein the private communication channel is dynamically established as a temporary communication channel for a duration of completing the transmitted captured audio to the second participant.

15. A computer program product for private audio communication in a conference call, comprising:

one or more computer-readable storage media and program instructions collectively stored on the one or more computer-readable storage media, the program instructions executable by a processor to cause the processor to perform a method comprising:

receiving a mute request from a first device of a first participant in a conference call;

muting a first audio output from the first device to the conference call;

capturing an audio from the first participant using a first microphone of the first device, wherein the muted first audio output prevents the captured audio from being heard in the conference call; and

transmitting the captured audio to a second participant in the conference call over a private communication channel.

16. The computer program product of claim 15 , wherein the transmitted captured audio is playable to the second participant without notifying other participants in the conference call.

17. The computer program product of claim 15 , further comprising:

determining the second participant for receiving the transmitted captured audio based on a destination input from the first participant.

18. The computer program product of claim 15 , further comprising:

detecting the second participant using a headset in the conference call; and

playing the transmitted captured audio using the headset of the second participant without notifying other participants in the conference call.

19. The computer program product of claim 15 , wherein the conference call further comprises a conference communication channel and the private communication channel in a same virtual meeting room, wherein the conference communication channel enables communication between all participants in the virtual meeting room, and wherein the private communication channel enables communication between the first participant and the second participant in the virtual meeting room, without notifying other participants in the virtual meeting room.

20. The computer program product of claim 15 , wherein the private communication channel is dynamically established as a temporary communication channel for a duration of completing the transmitted captured audio to the second participant.
