title: Setting language for TTS programmatically?
body: <p>I have written a small Android Demo to use TTS in different languages. I have a layout with two buttons, Spanish and English. Pressing the button triggers an utterance in the language selected.</p>
  
  <p>However, I can't change the language (setLanguage (Locale locale)). I can do it by hand, using the phone settings and changing the TTS language to US, UK, Italian, German, etc, but my code doesn't seem to work. Could you tell me where the problem is?</p>
  
  <p>Thank you!!</p>
