Voice Active Detection—Voice activity detection (VAD) is a technique used
in speech processing in which the presence or absence of human speech is
detected. The main uses of VAD are in speech coding and speech recognition.
It can facilitate speech processing and can also be used to deactivate some
processes during a non-speech portion of an audio session. This technique is
used to avoid unnecessary coding and transmission of silence packets in
Voice over Internet Protocol applications, saving on computational resources
and network bandwidth.
