SpeechSynthesis.cancel

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The cancel() method of the SpeechSynthesis interface removes all utterances from the utterance queue.

If an utterance is currently being spoken, speaking will stop immediately.

Syntax

speechSynthesisInstance.cancel();

Returns

Void.

Parameters

None.

Examples

var synth = window.speechSynthesis;

var utterance1 = new SpeechSynthesisUtterance('How about we say this now? This is quite a long sentence to say.');
var utterance2 = new SpeechSynthesisUtterance('We should say another sentence too, just to be on the safe side.');

synth.speak(utterance1);
synth.speak(utterance2);

synth.cancel(); // utterance1 stops being spoken immediately, and both are removed from the queue
