Google Text to Voice API in PHP

Since there is no specific API for converting text to speech, but it can be obtained through the Google URLs of Google translation service. There is a limit of this service. You can convert only 100 characters into speech. The code returns you an mp3 file.

[In this example we used <audio>  tag , which is used in HTML5. So please use Chrome or Mozilla Firefox to test that]

<?php

 class TextToSpeech {
 public $mp3data;
 function __construct($text="") {
        $text = trim($text);
        if(!empty($text)) {
            $text = urlencode($text);
            $this->mp3data = file_get_contents("http://translate.google.com/translate_tts?q={$text}");
        }
    }
 
    function setText($text) {
        $text = trim($text);
        if(!empty($text)) {
            $text = urlencode($text);
            $this->mp3data = file_get_contents("http://translate.google.com/translate_tts?q={$text}");
            return $mp3data;
        } else { return false; }
    }
 
    function saveToFile($filename) {
        $filename = trim($filename);
        if(!empty($filename)) {
            return file_put_contents($filename,$this->mp3data);
        } else { return false; }
    }
 
}

$data="Hello, I am testing the API.";

$tts = new TextToSpeech();
$tts->setText($data);
$tts->saveToFile("masnun.mp3");

?>
