How do you detect voice activity?

Voice activity detection (VAD) is a technique in which the presence or absence of human speech is detected. The detection can be used to trigger a process. VAD has been applied in speech-controlled applications and devices like smartphones, which can be operated by using speech commands.

What is VAD in networking?

Voice Activity Detection

With VoIP networks, all conversation and silence is packetized. With Voice Activity Detection (VAD), packets of silence can be suppressed. Over time and as an average on a volume of more than 24 calls, VAD can provide up to a 35 percent bandwidth savings.

What is voice activity factor?

Voice activity detection (VAD), also known as speech activity detection or speech detection, is the detection of the presence or absence of human speech, used in speech processing. The main uses of VAD are in speech coding and speech recognition.
