Background Noise Suppression
Background noise suppression (BNS) is designed primarily for hands-free operation and reduces
background noise to enhance communication in noisy environments.
Automatic Gain Control
Automatic Gain Control (AGC) is applicable to hands-free operation and is used to keep audio
output at nearly a constant level by adjusting the gain of signals in certain circumstances. This
increases the effective user-phone radius and helps with the intelligibility of talkers.
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.
