speechjs

A Library for speech recognition and synthesis.

Example (Recognition)

// Turn non-stop mode on
setSpeechRecVar('non-stop', true);

// Turn continuous (interim) mode on
setSpeechRecVar('interim', true);

// Anytime somebody speaks
function speechRecognized(result) {
	if (result.toBool) {
  		document.getElementById('result').innerHTML = result.toString;

  		// Is it an interim result (this will never be
  		// true if you don't turn interim mode on)
  		if (result.isInterim) {
  			document.getElementById('result').innerHTML += ' (interim)';
  		} else {
  			document.getElementById('result').innerHTML += ' (final)';
  		}
  	}
}

// Start listening
startRec();

Browser Support:

// Set default voice to "Alex"

endedSpeaking(function() {
	document.body.style.background = '#000';
});

window.onclick = function() {
	// Get a random available voice
	var voice = Math.floor(Math.random() * getVoiceNames().length);
	voice = getVoiceNames()[voice];

	// Set voice to that voice
	setSpeechSynthVar('voice', voice);

	// Say it again
