onAudioEnd not work about cognitive-services-speech-sdk-js

[jackiealex]

My solution: it helps the developers to know the timing of voice ending

const audioBuffer = this.audioContext.createBuffer(1, audioData.length, 22050)
const bufferSource = this.bufferSource = this.audioContext.createBufferSource()
bufferSource.buffer = audioBuffer
bufferSource.onended = event => {
     emit('status', 'end')// any ways to emit the event are ok
}

such code would help a lot, the developers may use it to synthesis many statements, once knowing the timing of statement complement, they will synthesis the next statement by producer-consumer model

@jackiealex, you have to execute .close() method inside the callback of speakTextAsync to make onAudioEnd event work.

See this stackoverflow issue: https://stackoverflow.com/questions/62564402/microsoft-cognitive-tts-onaudioend-event-not-working

P.S. I had the same problem and this solved it for me.
