We need a very simple iPhone app.
The app will have one previously stored sound file (wav file, for instance). That file will have a length of about 1, 2 or 3 seconds and will be a human voice (one word or two).
The app has to continuously listen what is received from the microphone and show in the screen a number indicating the "similarity" of what is hearing with the previously stored sound file, in a scale from 0% to 100%.
In case it is very close to what is prerecorded, the screen will show a high number ("86%" for instance). If it does not have similarity, it will show "0%".
We are not searching for exactness but approximation in different grades.
We understand that this has to be developed by someone that understands sound waves and how to sample them.
The developer does not have to worry about the graphics and the interface design.
The code has to be of good quality and not use APIs not approved by Apple.
Please do not bid if you have no experience with sound/voice related apps.
Please do not bid if you have never developed an iPhone app.
