Stopping Audio Playback Mid-Stream with Microsoft Neural TTS Service and Speech SDK

Question

I'm working with the Microsoft Neural Text-to-Speech (TTS) service using the Speech SDK. I've successfully implemented audio playback, but I'm facing a challenge with controlling the playback mid-stream.

My question is: How can I implement a feature to stop the audio playback at any given moment while using the Speech SDK with the Neural TTS service?

Specifically, I'm looking for:

The appropriate method or function to call for stopping audio playback

Any considerations or best practices for handling this interruption

Examples or code snippets demonstrating how to implement this feature (in Javascript)

I appreciate any guidance or solutions you can provide. Thank you in advance for your help!

Hello MD SHAKIL KHAN,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that you would like to stop audio playback mid-stream using the Microsoft Neural Text-to-Speech (TTS) service with the Speech SDK in JavaScript.

You can call the close method on the AudioConfig object to stop the audio playback using JavaScript, Where startSynthesis starts the speech synthesis and stopSynthesis stops the audio playback by calling the close method on the audioConfig object. An example of how you can implement ii is here below:

const sdk = require("microsoft-cognitiveservices-speech-sdk");
// Initialize the Speech SDK
const speechConfig = sdk.SpeechConfig.fromSubscription("YourSubscriptionKey", "YourServiceRegion");
const audioConfig = sdk.AudioConfig.fromDefaultSpeakerOutput();
// Create a speech synthesizer
const synthesizer = new sdk.SpeechSynthesizer(speechConfig, audioConfig);
// Function to start speech synthesis
function startSynthesis(text) {
    synthesizer.speakTextAsync(
        text,
        result => {
            if (result.reason === sdk.ResultReason.SynthesizingAudioCompleted) {
                console.log("Synthesis completed.");
            } else {
                console.error("Synthesis failed. Error details: " + result.errorDetails);
            }
        },
        error => {
            console.error("Error during synthesis: " + error);
        }
    );
}
// Function to stop speech synthesis
function stopSynthesis() {
    audioConfig.close();
    console.log("Audio playback stopped.");
}

You can modify it to suite your application.

I hope this is helpful! Do not hesitate to let me know if you have any other questions.
