webkitSpeechRecognition在start()之后立即调用onend

Question

只要我调用rec.start()，它就会直接调用onstart和onend，再也不会进入onresult。

麦克风是允许用于网页的，它曾经问过一次，因为在osx上使用Chrome81.0.4044.122是https，这被列为支持speechRecognition。

我知道这在浏览器中不是一个稳定的特性，但是运行安阳演示，检测我的声音，我相信这是使用相同的speechRecognition工具包。https://www.talater.com/annyang/

有什么想法吗？

以下是我的代码

if (!window.webkitSpeechRecognition) {
  // not called, so assume browser supports webkitSpeechRecognition
  alert('Your browser doesn\'t support speech to text.\nTry Chrome 33+ :)');
} else {
  const promise = new Promise((resolve, reject) => {
    const recognition = new webkitSpeechRecognition();
    recognition.lang = lang;
    recognition.continuous = true; // tried true and false

    recognition.onstart = (e) => {
      // called immediately after .start() as expected
      console.log("onstart");
    }
    recognition.onend = () => {
      // called immediately after onstart, not as expected
      console.log("onend");
    }
    recognition.onresult = function(event) {
      // never called, because it ended as soon as it started
      console.log("onresult");
    };
    // also tried the following formats
    // recognition.onresult = (event) => {};
    // recognition.addEventListener('onresult', (event) => {};
    // original example written like the following
    // recognition.addEventListener('result', (event) => {};

    recognition.start();
  });
  return await promise;
}

抱歉，伙计们，这是浏览器问题。

Chrome说它已经更新了，但实际上它仍然需要重新启动，只有在进入Chrome偏好设置后才能看到。

我现在在台式机和Android平板电脑上都有83.0.4103.83，看起来工作正常。
