Question

我正在使用SpeechRecognition和麦克风，并使用speechSynthesis将数据传回给我。

我在页面加载时使声音成为女性声音，并希望能够通过说出“男性声音”来切换到男性声音，然后传达“我现在是男人”。我后来也希望能够做相反的事情 - 当它设置为男性声音时，说“女性声音”并且它会切换回来。

我现在可以这样做，但男声只会说一次，因为声音没有被保存，只作为一个参数传递。因此，接下来说的话就会回到女声：

recyclerView.setNestedScrollingEnabled(false);

我尝试使用全局变量，使let voices = []; window.speechSynthesis.onvoiceschanged = function() { voices = window.speechSynthesis.getVoices(); }; function loadVoices(message, voice) { const msg = new SpeechSynthesisUtterance(); msg.voice = voice || voices[48]; // female voice msg.text = message; speechSynthesis.speak(msg); }; // asking for voice change here if (transcript.includes('male voice')) { let message = ('I am now a man'); let voice = voices[50]; // male voice loadVoices(message, voice); }指向全局变量，但这不起作用，再加上语音恢复为默认值（电子语音）：

msg.voice

如果我在let voiceGender = voices[48]; function loadVoices(message) { const msg = new SpeechSynthesisUtterance(); msg.voice = voiceGender // now a variable pointing to another. msg.text = message; speechSynthesis.speak(msg); }; if (transcript.includes('male voice')) { let message = ('I am now a man'); let voiceGender = voices[50]; // changing the global variable loadVoices(message); }内声明voiceGender，那么我无法从另一个函数中的loadVoices()更改它。

如何设置Javascript结构以便实现此目的？

我通过在loadVoices函数中添加一个带有条件的函数和布尔值来解决它：

// on pageload the voice is set to a female voice
let femaleVoice = true;

function loadVoices(message) {
  const msg = new SpeechSynthesisUtterance();

  // checks the boolean
  if (femaleVoice) {
    msg.voice = voices[48];
  } else {
    msg.voice = voices[50];
  }

  msg.text = message;
  speechSynthesis.speak(msg);
};

// changes the boolean / changes the gender of the SpeechSynthesisUtterance voice
function changeVoice() {
  if (femaleVoice) {
    femaleVoice = false;
  } else {
    femaleVoice = true;
  }
}

if (transcript.includes('male voice') || transcript.includes('female voice') ) {
  // calls the function to change the boolean.
  changeVoice();

  let message = ('I now have a different voice');
  loadVoices(message);
}

它确实添加了比原先想要的更多的线条，但绝对有效。
