Google SpeechRecognition and W3C Speech API

Question

I'm trying to use google WEB SPEECH API, but I have a problem with taht. I'm new in programming. So I wanna make something like that - https://www.google.com/intl/en/chrome/demos/speech.html

But, when I use examples from API, thre is an error. The object not defined... And I dont know why. I'm trying use this code

 <script type="text/javascript">
    var recognition = new SpeechRecognition();
    recognition.onresult = function(event) {
      if (event.results.length > 0) {
        q.value = event.results[0][0].transcript;
        q.form.submit();
      }
    }
  </script>

  <form action="http://www.example.com/search">
    <input type="search" id="q" name="q" size=60>
    <input type="button" value="Click to Speak" onclick="recognition.start()">
  </form>

Can anyone help my with that??? thx.

Google didn't exactly implement W3C API specification, they have minor differences. The object name is webkitSpeechRecognition, not SpeechRecognition. You can find examples on webkit API here:
