网络语音api语音合成 - 获取语音列表

Question

网络语音api我有一个奇怪的问题.我已经设置了一些代码来说出一串文字 - 很少,它用正常的声音说话("Alex"来自Mac OS X中的听写和语音设置).但通常情况下,它的声音是"阿尔伯特".

我正在看这里列出的w3c网络语音api:

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

并且有一个名为的界面

SpeechSynthesisVoiceList {}

我试图访问此功能,但我不能.

我该如何访问此语音列表？我正在使用铬金丝雀,我已经尝试了很多这样做的方法.我期望的工作是:

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

要么

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

我也跑:

console.log(window)

我看到很多关于网络语音api和语音合成的事情,但没有关于声音的事情.

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