Check the Browser compatibility table carefully before using this in production.
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
speechSynthesisInstance.speak(utterance);
Returns
Void.
Parameters
- utterance
- A
SpeechSynthesisUtterance
object.
Examples
This snippet is excerpted from our Speech synthesiser demo. 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.
var synth = window.speechSynthesis;
...
inputForm.onsubmit = function(event) {
event.preventDefault();
var utterThis = new SpeechSynthesisUtterance(inputTxt.value);
var selectedOption = voiceSelect.selectedOptions[0].getAttribute('data-name');
for(i = 0; i < voices.length ; i++) {
if(voices[i].name === selectedOption) {
utterThis.voice = voices[i];
}
}
synth.speak(utterThis);
inputTxt.blur();
}
