Web/API/RTCOfferAnswerOptions/voiceActivityDetection

ObsoleteThis feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The voiceActivityDetection property of the RTCOfferAnswerOptions dictionary is used to specify whether or not to use automatic voice detection for the audio on an RTCPeerConnection. The default value, true, indicates that voice detection should be used and that if possible, the user agent should automatically disable or mute outgoing audio when the audio source is not sensing a human voice.

Syntax

var options = {
  voiceActivityDetection: trueOrFalse
};

Value

A Boolean value indicating whether or not the connection should use voice detection once running. The default value, true, indicates that the user agent should monitor the audio coming from the microphone or other audio source and automatically cease transmitting data or mute when the user isn't speaking into the microphone,

A value of false indicates that the audio should continue to be transmitted regardless of whether or not speech is detected.
