How can we extract mfcc feature of an audio file (total 39 comprised of normal-delta-double delta) having window lenght of 25ms and window shift of 10ms?

Mudit,
Check out the mfcc function in Audio Toolbox.
[audioIn,fs] = audioread('Counting-16-44p1-mono-15secs.wav');
winLength = round(0.025 * fs);
overlapLength = round(0.015 * fs);
[coeffs,delta,deltadelta] = mfcc(audioIn,fs,'WindowLength',winLength,...
'OverlapLength',overlapLength,...
'NumCoeffs',13','LogEnergy','Ignore');
