how to set volume threshold to let VAD work (AUD-4854) #1068

Closed Jackyliszsh closed 1 month ago

Jackyliszsh commented 1 year ago

If the volume is not so high, VAD can not detect the speech. Is there API to set the volume threshold to let VAD check out the speech even with low volume?

@Jackyliszsh The VAD can detect speech only there is enough SNR. If the volume is too low, VAD can't works well. You can try the the VAD threshold https://github.com/espressif/esp-sr/blob/0c1eecaac259af95f76723b61d4e16cef5904fc7/include/esp32/esp_vad.h#L36
