Abstract: A method includes generating first audio data based on sound detected by a sound sensor at a first time. The method further includes transmitting, via one or more communication interfaces, the first audio data to another device during a communication session based on a determination that the sound sensor is unmuted with respect to the communication session at the first time. The method further includes generating second audio data based on sound detected by the sound sensor at a second time. The method further includes refraining from transmitting the second audio data to the other device during the communication session based on a determination that the sound sensor is muted with respect to the communication session at the second time. The method further includes initiating a natural language processing operation on the second audio data based on detecting a wake phrase in the second audio data.

Abstract: A conferencing endpoint includes a loudspeaker component, a base microphone, and an adaptive volume control module which evaluates near-end audio conditions at a conferencing endpoint and automatically determines whether to change the audio volume at a near-end loudspeaker. The endpoint can, for example, detect that a person speaking into the base microphone has begun to speak more loudly to compensate for nearby background noise. The endpoint can automatically adjust the loudspeaker volume or provide an alert that the loudspeaker will be changed, giving the user the opportunity to accept or decline an increase in speaker volume.
