SpeechSynthesis: paused property

The paused read-only property of the SpeechSynthesis interface is a boolean value that returns true if the SpeechSynthesis object is in a paused state, or false if not.

It can be set to paused even if nothing is currently being spoken through it. If utterances are then added to the utterance queue, they will not be spoken until the SpeechSynthesis object is unpaused, using SpeechSynthesis.resume().

const synth = window.speechSynthesis;

synth.pause();

const amIPaused = synth.paused; // will return true
