var canPlayOgg = !!(new Audio().canPlayType('audio/ogg; codecs="vorbis"'));
if(canPlayOgg == true){
	ispeech = "http://api.ispeech.org/api/rest?apikey=developerdemokeydeveloperdemokey&action=convert&voice=usenglishmale&format=ogg&text=";
} else{
	ispeech = "http://api.ispeech.org/api/rest?apikey=developerdemokeydeveloperdemokey&action=convert&voice=usenglishmale&text=";
}
$("#submit").click(function(){
	message = $("#text").val();
	$("audio").attr({
