Voice Activity Detection - Yealink SIP T46G Administrator's Manual

Administrator's Guide for SIP-T46G IP Phone
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 can also be used to 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 on
network bandwidth.
Procedure
