Speech to Text on Android

I am looking to create an app which has Speech to text.

I am aware of this kind of ability using the RecognizerIntent: http://android-developers.blogspot.com/search/label/Speech%20Input

However - I do not want a new Intent to be popped up, I want to do the analysis a certain points in my current app, and I dont want it to pop something up stating that it is currently attempting to record your voice.

Has anybody any ideas on how best to do this. I was perhaps thinking of trying Sphinx 4 - but I dont know if this would be able to run on Android - has anyone got any advice or experience?!

I was wondering if I could alter the code here to perhaps not bothering to show the UI or button and just do the processing: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html

Cheers,
