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
