// Convert Words (text) to Speech (MP3)

$word=$_POST['word'];
// Google Translate API cannot handle strings > 100 characters
$word = substr($word, 0, 100);
// Replace the non-alphanumeric characters
// The spaces in the sentence are replaced with the Plus symbol
$word = urlencode($word);
// If the MP3 file exists, do not create a new request
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, 'http://translate.google.com/translate_tts?ie=UTF-8&tl=en&q='.$word);
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the mp3 file
$mp3 = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
file_put_contents('temp/'.$word.'.mp3', $mp3);
