Question

SpeechSynthesis API在Firefox上不会说普通话。它不受支持吗？我无法在文档中找到列表。我尝试了几种不同的语言tags。

var msg = new SpeechSynthesisUtterance();
msg.text = '你好';
msg.lang = 'zh';
window.speechSynthesis.speak(msg);

（你应该听到＆＃34; nihao＆＃34;如果它有效。它在Chrome上听起来很好，在Safari上听起来 OK 。在Ubuntu上的Firefox 53.0.2上，我听到＆＃34;信函＆＃34;。）

在Windows上，Firefox只有3个声音，都是英语。

我写了一个显示浏览器声音的jsbin：

if ('speechSynthesis' in window) {
    // Start an html table for languages details
    var text = '<table border=1><tr><th>Default<th>Language<th>Local<th>Name<th>URI</tr>';
    // Get voices; add to table markup
    function loadVoices() {
        var voices = speechSynthesis.getVoices();
        voices.forEach(function(voice, i) {
          // Add all details to table
          text += '<tr><td>' + voice.default + '<td>'
              + voice.lang + '<td>' + voice.localService
              + '<td>' + voice.name + '<td>' + voice.voiceURI;
        });
    }
    loadVoices();
    langList.innerHTML = text;
    // Chrome loads voices asynchronously.
    window.speechSynthesis.onvoiceschanged = function(e) {
        loadVoices();
        langList.innerHTML = text;
    }
}
