%Reading the audio

y=audioread('speech.wav');

%sound(y);

subplot(2,3,1);

plot(y);

xlabel('Samples');

ylabel('Magnitude');

title('Original speech signal');

%Adding noise

x=awgn(y,5);

z=y+x;

z=z / max(abs(z));

%sound(z);

subplot(2,3,2);

plot(z);

xlabel('Samples');

ylabel('Magnitude');

title('Noise added to speech signal');

% Framing

f_duration = 0.025;

fs=8000;

f_size = (f_duration.*fs);

n = length(y);

n_f = floor(n/f_size); %no. of frames

temp = 0;

for i = 1 : n_f

frames(i,:) = z(temp + 1 : temp + f_size);

window=hamming(200);

window_framing(i,:)=frames(i,:).*window;

temp = temp + f_size;

end

I am trying to generalize the code for hamming windowing for every frame. But it is giving me "Unable to perform assignment because the indices on the left side are not compatible with the size of the right side." this error. Please resolve my query.
