I am using SpeechSynthesizer for TTS from "microsoft-cognitiveservices-speech-sdk"

Intermittently I the voice does not emit audio and I see this in the console.log:

SpeakerAudioDestination.js?38ca:132 Uncaught DOMException: Failed to set the 'duration' property on 'MediaSource': The 'updating' attribute is true on one or more of this MediaSource's SourceBuffers.

    Hi Yutong!

    I've narrowed this down. Our application uses SpeechToText (startContinuousRecognitionAsync) and then performs Text To Speech (speakTextAsync), both using cognitiveservices SDK. The above error only happens when we use STT and TTS. The code for TTS is attached.239058-tts-managerts.txt
