SpeechSynthesisUtterance.lang
The lang
property of the SpeechSynthesisUtterance
interface gets and sets the language of the utterance.
If unset, the app's (i.e. the <html>
lang
value) lang will be used, or the user-agent default if that is unset too.
Value
A DOMString
representing a BCP 47 language tag.
Examples
var synth = window.speechSynthesis;
var inputForm = document.querySelector('form');
var inputTxt = document.querySelector('input');
var voiceSelect = document.querySelector('select');
var voices = synth.getVoices();
...
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];
}
}
utterThis.lang = 'en-US';
synth.speak(utterThis);
inputTxt.blur();
}
