What is VAD in speech recognition?

6.1 Introduction. Voice activity detection (VAD) is a technique in which the presence or absence of human speech is detected. The detection can be used to trigger a process. VAD has been applied in speech-controlled applications and devices like smartphones, which can be operated by using speech commands.

What is VAD in VoIP?

The voice activity detection (VAD) feature discriminates between silence and speech on a voice connection according to their energies. With VAD, a POTS entity does not generate traffic during periods of silence in an active voice connection.

What is WebRTC VAD?

This is a python interface to the WebRTC Voice Activity Detector (VAD). It is compatible with Python 2 and Python 3. A VAD classifies a piece of audio data as being voiced or unvoiced. It can be useful for telephony and speech recognition.

What is VAD in machine learning?
