Web Speech API Audio to Variable

Question

是否可以将结果音频从Web Speech API（https://developers.google.com/web/updates/2014/01/Web-apps-that-talk-Introduction-to-the-Speech-Synthesis-API）返回到可以通过Audio对象使用的变量？

即。类似下面的内容（伪代码）：

var msg = new SpeechSynthesisUtterance('Hello World');
var speechToAudioFileLink = speechSynthesis.speak(msg);
var audio = new Audio(speechToAudioFileLink);
audio.play();
