SpeechSynthesis.pending

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage 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 specification changes.

The pending read-only property of the SpeechSynthesis interface is a Boolean that returns true if the utterance queue contains as-yet-unspoken utterances.

Syntax

JavaScript
var amIPending = speechSynthesisInstance.pending;

Value

A Boolean.

Examples

JavaScript
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
