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
