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.
speechSynthesisInstance.cancel();
Void.
None.
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
