error while using melcepst

i am doing a project on voice recognition, in order to compare i am using melcepst here is the code snippet

clear
input_signal_1=wavread('andrea hello.wav');
input_signal_2=wavread('john hello.wav');
[ceps_1,freqresp,fb,fbrecon,freqrecon] =mfcc(input_signal_1, 16000);
[ceps_2,freqresp,fb,fbrecon,freqrecon] =mfcc(input_signal_2, 16000);

% measure the distance between ceps_1 and ceps_2

% distance_measured=disteusq(ceps_1, ceps_2); % this was giving me big values, so 
% distance_average=mean(distance_measured) % i used the distance function f % below

distance_measured=distance(ceps_1, ceps_2);
distance_average=mean(distance_measured);
toatal_mfcc=mean(distance_average)

i am getting error as Error using mffc

 Undefined function 'mffc' for input arguments of type 'double'.

Error using melcepst instead of mffc

Too many output arguments.

mfcc does not appear to be part of MATLAB. It appears to be a routine from the File Exchange . You will need to download it and install it.
