The pending
read-only property of the SpeechSynthesis
interface is a Boolean
that returns true
if the utterance queue contains as-yet-unspoken utterances.
var amIPending = speechSynthesisInstance.pending;
A Boolean
.
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 amIPending = synth.pending; // will return true if utterance 1 is still being spoken and utterance 2 is in the queue
