I would like to offer you my project: iphone app
It will be very simple app which will use google voice engine for "listening" the iphone user and making that audio into text. Recently google has released voice search for android users where they are using same google voice engine to understand what the user is talking.
I didnt prepared the design but will send you all you need. UI will be very simple and easy to use.
Can you tell me what would be your estimation time and price for this project. I am aware that this is not complicated project, since its uses voice engine of google.
