How do I Split the characters from Speech to Text - Android

I have managed to create Speech to Text app which takes the users input and then inserts it into a textbox.

My next goal is to split the words spoken and insert that into the textbox. For example if the user says King Henry 2001 - the app extracts the first two characters of each word (KH) and any numbers (KH2001).

I have used the code for speech recognition from this site: http://www.androidhive.info/2014/07/android-speech-to-text-tutorial/

Is this possible?

Thank You
