public function play(play:String):void
        {
            if(playsound==false)
            {
                playsound = true;
                setTimeout(soundtimer, 10000);
                var qpar:String = "q=" + encodeURIComponent(play);
                var sound:Sound = new Sound();
                sound.addEventListener(ProgressEvent.PROGRESS, onLoadProgress);
                sound.addEventListener(Event.COMPLETE, onLoadComplete);
                var request:URLRequest = new URLRequest("http://translate.google.com/translate_tts?" + qpar + "&tl=ru&prev=input");
                sound.load(request);
            }
        }

Вот код.

Применяю его так:

play(слова произношения);
