WebSearch API 語音識別不適用於 Android Mobile

Question

我正在嘗試創建一個漸進式 Web 應用程序，我需要在其中實現連續語音識別功能。 到目前為止，它在 Chrome 桌面應用程序上運行良好，但不適用於我的手機。 它甚至不要求麥克風許可。

window.SpeechRecognition =
  window.webkitSpeechRecognition || window.SpeechRecognition;
let finalTranscript = "";
let recognition = new window.SpeechRecognition();
//morjs.defineMode("smartjava", [".", "-", "", " ", "|"]);
//morjs.mode("smartjava", [".", "-", "", " ", "|"]);

recognition.interimResults = true;
recognition.maxAlternatives = 10;
recognition.continuous = true;

recognition.onresult = event => {
  let interimTranscript = "";
  for (let i = event.resultIndex, len = event.results.length; i < len; i++) {
    let transcript = event.results[i][0].transcript;
    if (event.results[i].isFinal) {
      console.log(transcript);
      morse(transcript);
      // var encoded = morjs.encode({ message: transcript, mode: "simple" });
      finalTranscript += transcript;
      // var toPlay = playMorseCode(encoded);
      // navigator.mozVibrate(toPlay);
    } else {
      //console.log(transcript);
      //morse(transcript);
      // var encoded = morjs.encode({ message: transcript, mode: "simp;e" });
      interimTranscript += transcript;
      // var toPlay = playMorseCode(encoded);
      // navigator.mozVibrate(toPlay);
    }
  }

  document.querySelector("test").innerHTML =
    finalTranscript + '<i style="color:#ddd;">' + interimTranscript + "</>";
};
recognition.start();

取決於您在移動設備上使用的瀏覽器。 目前它僅適用於 Android 上的 Chrome：
