title: Automatically download android TTS engine
body: <p>I have developed an app based on TTS for Android 2.3. 
  I am noticing that in recent version of Android (4.2.2) for example, no default TTS language where installed by default, you have to manually download them by going into:
  Settings --> Language and input --> Text to speech output --> Google Text-To-speech --> Install voice data</p>
  
  <p>Is there a way to install a language automatically? </p>
