webkitSpeechRecognition 自动停止

Question

I am using webkitSpeechRecognition. But when recognition is initiated, it stops after 1-2 mins of inactivity. I am trying to firing it back after it is ended. When I execute start_transcript(language), it keeps producing a thousand of console.log("voice recognition terminated"); and it does not recongnize anymore.

var final_transcript = '';
var recognizing = false;
var start_timestamp;
if (!('webkitSpeechRecognition' in window)) {
  upgrade();
} else {
  var recognition = new webkitSpeechRecognition();
  recognition.continuous = true;
  recognition.interimResults = true;
  recognition.onstart = function() {
    recognizing = true;
  };

  recognition.onend = function() {
    console.log("voice recognition terminated");
    recognition.start();
  };

function start_transcript(language) {
  if (recognizing) {
    recognition.stop();
    return;
  }
  final_transcript = '';
  var rec_lang = 'fr-FR';
    recognition.lang = rec_lang;
  recognition.start();
}

Any help and advice will be very appreciated.

Thanks

Just some tiny missings here and there. Updated your code with filling those missing gaps,Try this in your console. Also don't forget to call start_transcript .

 var final_transcript = ''; var recognizing = false; var start_timestamp; if (!('webkitSpeechRecognition' in window)) { upgrade(); } else { var recognition = new webkitSpeechRecognition(); recognition.continuous = true; recognition.interimResults = true; recognition.onstart = function() { recognizing = true; }; // need to have result as well recognition.onresult = function(e) { console.log(e.results); // Extracting the words from the result and printing in the console var transcript = [...e.results] .map(result => result[0]) .map(result => result.transcript) .join(''); console.log(transcript); }; recognition.onend = function() { console.log("voice recognition terminated"); recognition.start(); }; } // I guess you forgot closing the else block as well function start_transcript() { if (recognizing) { recognition.stop(); return; } final_transcript = ''; var rec_lang = 'fr-FR'; recognition.lang = rec_lang; recognition.start(); }

PS: Also I had made a similar kind of project by referring Wesbos's javascript30, and mixed it with webpack. If you want to refer it then please visit https://github.com/Mondal10/personal-voice-assistant
