问在web浏览器中，TRTC 实时音频中，如果判断自己是否在说话？

const stream = await navigator.mediaDevices.getUserMedia({ audio: true, video: false })
 const audioTrack = stream.getAudioTracks()[0];
 await audioTrack.applyConstraints({
        echoCancellation: true,
        noiseSuppression: true,
        autoGainControl: true,
 });
 const localStream = TRTC.createStream({
        audioSource: audioTrack,
        userId: this.userId
 });
 await localStream.initialize();
 this.client.publish(localStream);
 setInterval(() => {
 const level = localStream.getAudioLevel();
 console.log('level', level);
 if (level >= 0.1) {
 // 我自己的声音大于0.1, 则说明我自己在说话????
 }
 }, 200);
