点击播放网站上的Google Text to Speech Api

i have this paragraph

A tattoo of angel wings on the back of the young girl pointed officers to a runaway, a 15-year-old school girl called Tina Fontaine. Within days Tina's case was making headlines throughout Canada not just for the horrific nature of her death, but for what she had come to represent.

and want to play it on my website on click ! so far this is my best code, they say it cant handle more than 100 characters.

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

Any suggesions ? using only jquery / Javascript / PHP Thankyou

function say( text ){
  if('speechSynthesis' in window) { // Chrome only !!

    var speech = new SpeechSynthesisUtterance( text );
    speech.lang = 'en-US';
    window.speechSynthesis.speak(speech);

  } else { // Other browsers !!

     // Use AJAX (with GET) to a .php to file_get_contents
     // generate the <100 by <100 charaters audio files, and nest in callbacks

  }
}


say("A tattoo of angel wings can handle more than 100 characters");

The else part of the code

$("#playButton").click(function(){
    var string = encodeURIComponent( $("textarea").val() );
    // TODO: split 100+ string into chunks of rightly punctuated sentences.
    $.ajax({
        data: { text: string },
        success : function(d) {
            var audio = new Audio();
            audio.src = "data:audio/mpeg;base64,"+d;
            audio.play();
            audio.onended = function() {
                alert("Ended playing first part");
                // TODO : if we have chunks, play the next one!
            }
        }
    });
});

The php goes like: (you can put it inside the same page (at the top)!)

<?php 
if ($_SERVER['REQUEST_METHOD'] === 'GET' && isset($_GET['text']) && isset($_GET['lang'])) {
    $voice = file_get_contents("http://translate.google.com/translate_tts?q=". $_GET['text'] ."&tl=". $_GET['lang'] ."&ie=UTF-8");
    echo base64_encode( $voice );
    exit;
}
?>
