Android app for convert the voice of an incomming call in to text in real time

I need an Android App able to do this: 1) When the App is open show the incoming call and when i press a button inside the app to answer the incoming call i want to see the voice of the other person as a text inside the app. i don't need be able to talk with the other person at this moment, I just need to see what the other person say as a text, for example if the other person say: "Hello" i need to see in the label the word "Hello". See some examples below (what i need is more simple) [login to view URL] Only native Android code (Java) and eclipse as a IDE. New freelancers are very welcome. My budget is USD 100 and this is just the first part of a big project. Thanks!
