Mel frequency cepstrum help

[oiyela]

Hi, i am currently doing a project on speech recognition using a neural network. i have recorded all my sound sample and extracted it as a wav file. i have been able to read the wav file and display it on a time-domain graph and also a spectrogram.

i need to know convert the speech signal into mel frequency cepstrum coefficients, having difficulties understanding how to do this.

i found out this fuction

MFCC(S,FS,TW,TS,ALPHA,WINDOW,R,M,N,L)

S is the input speech signal (as vector)
%
% FS is the sampling frequency (Hz)
%
% TW is the analysis frame duration (ms)
%
% TS is the analysis frame shift (ms)
%
% ALPHA is the preemphasis coefficient
%
% WINDOW is a analysis window function handle
%
% R is the frequency range (Hz) for filterbank analysis
%
% M is the number of filterbank channels
%
% N is the number of cepstral coefficients
% (including the 0th coefficient)
%

I do not know what values to put in for TW,TS,ALPHA,WINDOW,R,M,N,L

Please help if you can thanks
