function gmmfeatures(voice,N,deltaN,fs,Q)
N=256; %number of frames
M=156; %number of overlapping frame
a(1:256,1:82)=0;a(:,1)= voice (1:256,1);
for j=2:82
a(:,j)= voice ((N-M)*j+1:(N-M)*j+N,1);
end
figure(3);
plot(a(:));
title('Frame blocking of the Voice Signal');
end
this function shows the frame blocking
