Check the Browser compatibility table carefully before using this in production.
The speaking
read-only property of the SpeechSynthesis
interface is a Boolean
that returns true
if an utterance is currently in the process of being spoken — even if SpeechSynthesis
is in a paused
state.
Syntax
var amISpeaking = speechSynthesisInstance.speaking;
Value
A Boolean
.
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); var amISpeaking = synth.speaking; // will return true if utterance 1 or utterance 2 are currently being spoken
