title: continous speech recognition with Webkit speech api
body: <p>i started using this browser(chrome) feature. 
  i ve written a JS based on this , but the problem is even , it recognises the speech only once and ends . its not going continuously, i need to press the button again and again to start speech recognition . tell me where i should tweak . i ve set "recognition.continuous=true" still not helping ?</p>
  
  <pre><code>var recognition = new webkitSpeechRecognition();
  recognition.continuous     = true;
  recognition.interimResults = true;
  
  recognition.onstart = function() {
    console.log("Recognition started");
  };
  recognition.onresult = function(event){
    console.log(event.results);
  };
  recognition.onerror = function(e) {
    console.log("Error");
  };
  
  recognition.onend = function() {
    console.log("Speech recognition ended");
  };
  
  function start_speech() {
    recognition.lang = 'en-IN'; // 'en-US' works too, as do many others
    recognition.start();
  }
  </code></pre>
  
  <p>I call "start_speech" from a button ! thats it  </p>
