推荐答案

下面是一些code和的一jsbin以及，以帮助演示如何使用API​​一起使用：

Here's some code and a jsbin as well to help demonstrate how to use the APIs together:

var utterance = new window.SpeechSynthesisUtterance();
utterance.lang = 'ja-JP'; //translates on the fly - soooo awesome (japanese is the funniest)
utterance.volume = 1.0;
utterance.rate = 1.0;
utterance.pitch = 1.0;
utterance.voice = 'Hysterical'; // this seems to do nothing
utterance.text = "Facebook news feeds are full of garbage";

//Speak the phrase
window.speechSynthesis.speak(utterance);

window.speechSynthesis.onvoiceschanged = function () {
  var speechSynthesisVoices = speechSynthesis.getVoices();
  var accents = _(speechSynthesisVoices).pluck('lang');
  var voices = _(speechSynthesisVoices).pluck('voiceURI');
  var names = _(speechSynthesisVoices).pluck('name');
  console.log('names', names);
  console.log('accents', _.uniq(accents));
  console.log('voices', voices);
};
