speakTextAsync SynthesizingAudioCompleted indicator is raised in beginning of audio instead of end

[uri3000]

You can run this code and see how it happens:

const speak = async (text, onEnd, pitch = 1, rate = 0.35) => {
const tokenObj = await getTokenOrRefresh();
const speechConfig = speechsdk.SpeechConfig.fromAuthorizationToken(tokenObj.authToken, tokenObj.region);
speechConfig.speechSynthesisVoiceName = 'es-AR-ElenaNeural';
const audioConfig = speechsdk.AudioConfig.fromDefaultSpeakerOutput();
const synthesizer = new speechsdk.SpeechSynthesizer(speechConfig, audioConfig);

    synthesizer.speakTextAsync(text, result => {
        if (result.reason === ResultReason.SynthesizingAudioCompleted) {
          await onEnd(); // This runs in the start of the audio playback instead of in the end.
      
        } else {
            console.error('Speech was cancelled or could not be recognized. Ensure your microphone is working properly.');
        }
    });

}

I tried to change the call back to await but it doesn't work. Any idea? thanks.
await synthesizer.speakTextAsync

SynthesizingAudioCompleted means the service synthesized all audio and the client finished to receive them, instead of audio playing completed. You can refer to onAudioEnd

Hi, I am trying to download the file instead of playing it online.
Synthesizer.speakTextAsync is an async api but it doesn't works is the line below.
await synthesizer.speakTextAsync(text)

Many thanks.

That does not work, see issue: #699 (comment)
