circumstances. This increases the effective user-phone radius and helps with the
intelligibility of soft-talkers.
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.
Procedure
VAD can be configured using the configuration files or locally.
