I’m not sure how much doing steering (changing target_direction) dynamically works either. The webrtc library doesn’t implement DOA. I asked the pulse guys and they kindly replied. The webrtc AEC is really good but its debatable if the beamforming works and how without a differing DoA (Direction of Arrival) What are your setups? Are they working (better than mine, at least)? Well, the wakeword part if not good (I don’t know if the STT is any better), but standalone recording seem to be good.
