Voice Activity Detection
Voice Activity Detection (VAD) is used in speech processing to detect the presence or absence of
human speech. When detecting period of “silence”, VAD replaces that silence efficiently with
special packets that indicate silence is occurring. It can facilitate speech processing, and
deactivate some processes during non-speech section of an audio session. VAD can avoid
unnecessary coding or transmission of silence packets in VoIP applications, saving on
computation and network bandwidth.
