Web语音API语音合成-获取语音列表

Question

我有一个奇怪的问题与网络语音api。我设置了一些代码来发出一串文本——很少，它会发出正常的声音("Alex"来自Mac OS X的听写和语音设置)，但通常，它会发出"Albert"的声音。

我正在看这里列出的w3c web语音api:

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

有一个接口叫做

SpeechSynthesisVoiceList {}

我试图访问这个功能，但我不能。

我如何访问这个语音列表?我用的是铬金丝雀，我已经尝试了很多方法。我期望的工作是:

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

或

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

我还运行了:

console.log(window)

和我看到了很多关于网络语音api和语音合成的东西，但没有关于声音的。

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:
