SpeechSynthesisUtterance()
constructor of the
SpeechSynthesisUtterance
interface returns a new
SpeechSynthesisUtterance
对象实例。
var utterThis = new SpeechSynthesisUtterance(text);
DOMString
containing the text that will be synthesized when the utterance is spoken..
The following snippet is excerpted from our Speech synthesizer demo .
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];
}
}
synth.speak(utterThis);
inputTxt.blur();
}
