Mudit,

Check out the mfcc function in Audio Toolbox.

https://www.mathworks.com/help/audio/ref/mfcc.html

[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');
