This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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
