SpeechSynthesis: speak() method
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 speak() method of the SpeechSynthesis interface adds an utterance to the utterance queue; it will be spoken when any other utterances queued before it have been spoken.
Syntax
js
speak(utterance) Parameters
utterance-
A
SpeechSynthesisUtteranceobject.
Return value
None (undefined).
Examples
This snippet is excerpted from our Speech synthesizer demo (see it live). When a form containing the text we want to speak is submitted, we (amongst other things) create a new utterance containing this text, then speak it by passing it into speak() as a parameter.
js
const synth = window.speechSynthesis; // … inputForm.onsubmit = (event) => { event.preventDefault(); const utterThis = new SpeechSynthesisUtterance(inputTxt.value); const selectedOption = voiceSelect.selectedOptions[0].getAttribute("data-name"); for (const voice of voices) { if (voice.name === selectedOption) { utterThis.voice = voice; } } synth.speak(utterThis); inputTxt.blur(); }; Specifications
