title: Text to visual animation in android
body: <p>I have an android app in which I want to animate / visualize the text to speech . Like when the text is spoken by the app the app also blinks lights according to the voice data.</p>
  
  <p>The data is available as text which I would convert to speech using text to speech of android.
  The visual representation is like some LEDS blinking based on voice.</p>
  
  <p>Can someone please me guideline how to extract voice data(which features to extract) and then how to map it to some visual animation ?</p>
  
  <p>thanks, 
  Ahmed</p>
