This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use 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 spec changes.
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.
SyntaxEdit
var amISpeaking = speechSynthesisInstance.speaking;
Value
A Boolean
.
ExamplesEdit
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
