javascript - web speech api语音合成-获取语音列表

Question

我在使用网络语音 API 时遇到了一个奇怪的问题。我已经设置了一些代码来说出一串文本——很少，它会用正常的声音说出来(Mac OS X 中听写和语音设置中的“Alex”)。但通常情况下，它会用“Albert”的声音说话。

我正在查看此处列出的 w3c 网络语音 API:

https://dvcs.w3.org/hg/speech-api/raw-file/tip/speechapi.html#dfn-ttsgetvoices

还有一个接口(interface)叫做

SpeechSynthesisVoiceList{}

我正在尝试访问此功能，但我不能。

我如何访问此语音列表？我正在使用 chrome canary，我已经尝试了很多方法来做到这一点。我期望的工作是:

var u = new SpeechSynthesisUtterance();
  console.log(u.getVoices());

或

var u = new SpeechSynthesisVoiceList();
  console.log(u);

我也跑过:

console.log(window)

我看到很多关于网络语音 API 和语音合成的东西，但没有看到关于语音的东西。

您应该使用 speechSynthesis.getVoices() 来获取所有声音的列表。这是 Google Chrome 33 的输出:
