Using Google Text-To-Speech in Javascript

I need to play Google text-to-speech in JavaScript.
The idea is to use the web service:

http://translate.google.com/translate_tts?tl=en&q=This%20is%20just%20a%20test

And play it on a certian action, e.g. a button click.

But it seems that it is not like loading a normal wav/mp3 file:

<audio id="audiotag1" src="audio/example.wav" preload="auto"></audio>

<script type="text/javascript">
    function play() {
        document.getElementById('audiotag1').play();
    }
</script>

How can I do this?

Here is the code snippet I found:

var audio = new Audio();
audio.src ='http://translate.google.com/translate_tts?ie=utf-8&tl=en&q=Hello%20World.';
audio.play();

Another option now may be HTML5 text to speech, which is in Chrome 33+ and many others.

Here is a sample:

var msg = new SpeechSynthesisUtterance('Hello World');
window.speechSynthesis.speak(msg);

With this, perhaps you do not need to use a web service at all.

Very easy with responsive voice. Just include the js and voila!

<script src='https://code.responsivevoice.org/responsivevoice.js'></script>

<input onclick="responsiveVoice.speak('This is the text you want to speak');" type='button' value='

You can use the SpeechSynthesisUtterance with a function like say:

function say(m) {
  var msg = new SpeechSynthesisUtterance();
  var voices = window.speechSynthesis.getVoices();
  msg.voice = voices[10];
  msg.voiceURI = "native";
  msg.volume = 1;
  msg.rate = 1;
  msg.pitch = 0.8;
  msg.text = m;
  msg.lang = 'en-US';
  speechSynthesis.speak(msg);
}

Then you only need to call say(msg) when using it.

Update: Look at Google's Developer Blog that is about Voice Driven Web Apps Introduction to the Web Speech API.

            speechRecognizer.lang = 'en-IN';
            speechRecognizer.start();
            var finalTranscripts = '';
            speechRecognizer.onresult = function(event) {
                var interimTranscripts = '';
                for (var i = event.resultIndex; i < event.results.length; i++) {
                    var transcript = event.results[i][0].transcript;
                    transcript.replace("\n", "<br>");
                    if (event.results[i].isFinal) {
                        finalTranscripts += transcript;
                        var speechresult = finalTranscripts;
                        console.log(speechresult);
                        if (speechresult) {
                            responsiveVoice.speak(speechresult, "UK English Female", {
                                pitch: 1
                            }, {
                                rate: 1
                            });
                        }
                    } else {
                        interimTranscripts += transcript;
                    }
                }
                r.innerHTML = finalTranscripts + '<span style="color:#999">' + interimTranscripts + '</span>';
            };
            speechRecognizer.onerror = function(event) {};
        } else {
            r.innerHTML = 'Your browser is not supported. If google chrome, please upgrade!';
