Speech recognition system algorithm

Hi, I need help with Speech recognition algorithm for Matlab. Since I'm pretty new to this, I still haven't learned such complex coding which I need in order to create the speech recognition model.

I need MATLAB code for speech recognition system that will identify the person who is talking on the microphone based on recorded samples from the database of 10 different recorded people saying chosen keyword. Can anyone please help me with this? I work in Matlab version 2010a.

Thanks a lot!

Kind Regards, Thierry
