RTCOfferAnswerOptions.voiceActivityDetection

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

  voiceActivityDetection: trueOrFalse
};
