Member Data Documentation

◆ activePercent

float io.agora.rtc.AgoraAudioVadConfigV2.activePercent
private

The percentage of active frames required in startRecognizeCount frames to enter speaking state.

The default value is 0.7 (70%). The value range is [0.0, 1.0].

◆ inactivePercent

float io.agora.rtc.AgoraAudioVadConfigV2.inactivePercent
private

The percentage of inactive frames required in stopRecognizeCount frames to enter stop speaking state.

The default value is 0.5 (50%). The value range is [0.0, 1.0].

◆ preStartRecognizeCount

int io.agora.rtc.AgoraAudioVadConfigV2.preStartRecognizeCount
private

The number of audio frames to save before entering the start speaking state.

The default value is 16 (frames). The value range is [0, 2^31 - 1].

◆ startRecognizeCount

int io.agora.rtc.AgoraAudioVadConfigV2.startRecognizeCount
private

The number of audio frames required to confirm the speaking state.

The default value is 30 (frames). The value range is [1, 2^31 - 1].

◆ startRmsThreshold

int io.agora.rtc.AgoraAudioVadConfigV2.startRmsThreshold
private

The RMS threshold for starting the voice activity detection. The default value is -50. The value range is [-100, 0].

The higher the value, the more sensitive to voice activity.

  • In a quiet environment, you can set it to -50;
  • In a noisy environment, you can set it to a value between -40 and -30.

◆ startVoiceProb

int io.agora.rtc.AgoraAudioVadConfigV2.startVoiceProb
private

The threshold for starting the voice activity detection. The default value is 70. The value range is [0, 100].

The lower the value, the higher the probability that a frame is judged as activity, which allows the start phase to begin earlier.

Conversely, the higher the value, the lower the probability that a frame is judged as activity, and the higher the probability of being judged as inactivity, which makes the start phase to begin later.

◆ stopRecognizeCount

int io.agora.rtc.AgoraAudioVadConfigV2.stopRecognizeCount
private

The number of audio frames required to confirm the stop speaking state.

The default value is 20 (frames). The value range is [1, 2^31 - 1].

◆ stopRmsThreshold

int io.agora.rtc.AgoraAudioVadConfigV2.stopRmsThreshold
private

The RMS threshold for stopping the voice activiy detection. The default value is -50. The value range is [-100, 0].

The higher the value, the more sensitive to voice activity.

  • In a quiet environment, you can set it to -50;
  • In a noisy environment, you can set it to a value between -40 and -30.

◆ stopVoiceProb

int io.agora.rtc.AgoraAudioVadConfigV2.stopVoiceProb
private

The threshold for stopping the voice activity detection. The default value is 70. The value range is [0, 100].

The lower the value, the higher the probability that a frame is judged as activity, which makes the end phase to begin later.

Conversely, the higher the value, the lower the probability that a frame is judged as activity, and the higher the probability of being judged as inactivity, which allows the end phase to begin earlier.
