SpeechSynthesis: pending property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2018.

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

Value

A boolean value.

Examples

js
const synth = window.speechSynthesis;

const utterance1 = new SpeechSynthesisUtterance(
  "How about we say this now? This is quite a long sentence to say.",
);
const utterance2 = new SpeechSynthesisUtterance(
  "We should say another sentence too, just to be on the safe side.",
);

synth.speak(utterance1);
synth.speak(utterance2);

const amIPending = synth.pending; // will return true if utterance 1 is still being spoken and utterance 2 is in the queue
