Hi, Please i need help with this Matlab code. i am using this melcept function for different samples of me saying the word "one" here is my code

Code: [aaaaa1,fs]=wavread('one.wav'); %Read In Sample

a=0.95;

aaaa1=filter([1,-a],1,aaaaa1);

aaa1= melcepst(aaaa1,fs);

i get an output for the different samples of me saying one as 54x12 , 44x12, 50x12, 49x12 please for melcepst is possible to generate the same number of points for each row, i.e. nx12, n is the same for each sample.

here is the link to the description of the melcept function - http://www.ee.ic.ac.uk/hp/staff/dmb/.../melcepst.html

Is there any other way of doing MFCC and changing the number of coefficients. Also if i set the number of coeffcient as 12 should i get one line with 12 points or do i get 12 lines with a lots of points because of the frame blocking?

hi

im using mfcc too for my reseach. I hope this code can help you.

if 1 preEmphasized = filter([1 -.97], 1, input); else preEmphasized = input; end

a=buffer(preEmphasized,frame,overlap,'nodelay'); cols=size(a,2); ceps = zeros(cepstralCoefficients, cols);

what pattern recognition are you using for? may be you can help my problem in here:

just make sure you using same sampling rate, time frame, and overlap

i used sampling rate 11000, time frame 40, overlap 0.5. ceps 13

it will be generate matrix 13x35
