webrtcvad is a Python interface to the Google WebRTC Voice Activity Detector (VAD). It classifies short segments of audio as being voiced or unvoiced, useful for telephony and speech recognition. The current version is 2.0.10, with releases historically following an infrequent, as-needed cadence to incorporate upstream WebRTC VAD changes or bug fixes.
