Been trying to work out what voice_detection does I know its VAD but in terms of pulseaudio struggling to work out any effect or process?
Is it me? 😊

If you look at https://github.com/freedesktop/pulseaudio-webrtc-audio-processing/tree/master/webrtc/common_audio/vad
Then also much is the same.

Webrtc has vad and it would be great if that could either change stream params to phone or cork/duck or something.
I have been playing with AEC on a PI that isn’t great to be honest as often the result is an attenuated ‘vocody’ stream but actually if the vad could trigger cork/duck then it would be great to use.

So on the off chance it isn’t me, would there be any interest in linking webrtc vad to pulseaudio functionality, unfortunately speex vad seems only part of the codec rather than speexdsp but vad to cork/duck functionality parameters would be great IMHO.

Just thought I would float that as presuming it would be a minimal addition with little effect on existing.
