这是实验性技术
检查浏览器兼容性表格要小心谨慎在生产中使用这之前。

SpeechSynthesisVoice 接口在 Web 语音 API represents a voice that the system supports. Every SpeechSynthesisVoice has its own relative speech service including information about language, name and URI.

特性

SpeechSynthesisVoice.default 只读: 布尔 indicating whether the voice is the default voice for the current app language ( true ), or not ( false )。
SpeechSynthesisVoice.lang 只读
SpeechSynthesisVoice.localService 只读: 布尔 indicating whether the voice is supplied by a local speech synthesizer service ( true ), or a remote speech synthesizer service ( false )。
SpeechSynthesisVoice.name 只读
SpeechSynthesisVoice.voiceURI 只读

范例

The following snippet is excerpted from our Speech synthesiser demo .

function populateVoiceList() {
  voices = synth.getVoices();
  for(i = 0; i < voices.length ; i++) {
    var option = document.createElement('option');
    option.textContent = voices[i].name + ' (' + voices[i].lang + ')';
    if(voices[i].default) {
      option.textContent += ' -- DEFAULT';
    }
    option.setAttribute('data-lang', voices[i].lang);
    option.setAttribute('data-name', voices[i].name);
    voiceSelect.appendChild(option);
  }
}
populateVoiceList();
if (speechSynthesis.onvoiceschanged !== undefined) {
  speechSynthesis.onvoiceschanged = populateVoiceList;
}
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.pitch = pitch.value;
  utterThis.rate = rate.value;
  synth.speak(utterThis);
  utterThis.onpause = function(event) {
    var char = event.utterance.text.charAt(event.charIndex);
    console.log('Speech paused at character ' + event.charIndex + ' of "' +
    event.utterance.text + '", which is "' + char + '".');
  }
  inputTxt.blur();
}
