title: Alternative TTS engine?
body: <p>I have an android app that has a very nice voice when speaking English, and it is a different voice from the one in my tablet by default (Google TTS)</p>
  
  <p>How did they do that ? Is it possible to download tts packages, and integrate them in an app easily ?
  I managed to do text to speech easily with the user's default built in tts, but I have no idea where to start for changing this.</p>
