使用

Im working on webkitspeechrecognition converting voice to text.Here its working fine in chrome but not in fire fox.how to solve this issue.

What I have tried:

Used

webkitSpeechRecognition

<script type="text/javascript">
var final_transcript = '';
var recognizing = false;

if ('webkitSpeechRecognition' in window) {

  var recognition = new webkitSpeechRecognition();

  recognition.continuous = true;
  recognition.interimResults = true;

  recognition.onstart = function() {
    recognizing = true;
  };

  recognition.onerror = function(event) {
    console.log(event.error);
  };

  recognition.onend = function() {
    recognizing = false;
  };

  recognition.onresult = function(event) {
    var interim_transcript = '';
    for (var i = event.resultIndex; i < event.results.length; ++i) {
      if (event.results[i].isFinal) {
        final_transcript += event.results[i][0].transcript;
      } else {
        interim_transcript += event.results[i][0].transcript;
      }
    }
    final_transcript = capitalize(final_transcript);
    final_span.innerHTML = linebreak(final_transcript);
    interim_span.innerHTML = linebreak(interim_transcript);

  };
}

var two_line = /\n\n/g;
var one_line = /\n/g;
function linebreak(s) {
  return s.replace(two_line, '<p></p>').replace(one_line, '<br>');
}

function capitalize(s) {
  return s.replace(s.substr(0,1), function(m) { return m.toUpperCase(); });
}

function startDictation(event) {
  if (recognizing) {
    recognition.stop();
    return;
  }
  final_transcript = '';
  recognition.lang = 'en-US';
  recognition.start();
  final_span.innerHTML = '';
  interim_span.innerHTML = '';
}
</script>

推荐答案

你必须使用

var recognition = SpeechRecognition || webkitSpeechRecognition

Firefox的第一个，Chrome的第二个。

The first one for Firefox, the second one for Chrome.
