title: Handling multiple languages without delay in Android's TTS
body: <p>I have this problem: I'd like to let the TTS speak an English sentence with foreign words in it (for instance, Italian).
  The problem is that, after instancing a <code>TextToSpeech</code> class, every time I change language, it takes several seconds to load, and this is unacceptable since the sentence needs to be as fluid as possible.
  I also tried instancing more than one <code>TextToSpeech</code>, but the results are pretty much identical.</p>
  
  <p>I wasn't able to find something on Google, aside from <a href="https://stackoverflow.com/questions/26994354/android-two-instances-of-text-to-speech-work-very-slowly">this</a> question, which was unhelpful.</p>
  
  <p>Is there at all a way to achive this? How?</p>
  
  <p>Thanks in advance,
  Mauro.</p>
