How to get the Amplitude of TTS

Question

I am trying to listen TTS voice amplitude and silence in between words. I will use this for showing some animations synchronized with the TTS voice

I could not find a way to make it work. Hope it is possible if I could convert TTS to sound file and read it, but not sure.

Please advice me

If you need to synchronize the audio with visual actions, you'll have to set an TextToSpeech.OnUtteranceCompletedListener (or since ICS: an UtteranceProgressListener) to the TTS engine. That way you can determine when a specific piece of text has been synthesized.

Alternatively, you can synthesize the text to an audio file using the synthesizeToFile(String text, HashMap<String, String> params, String filename) method.
