Euclidian distance for speaker recognition system

Hi guys.

I'm new in Matlab and now I have a problem for the implementation of a simple speaker recognition system using PNCC and MFFC.

My problem is on matrix dimension in fact, when I run my program, it give me this error:

Matrix dimensions must agree.

Error in disteu (line 43)
        d(n,:) = sum((x(:, n+copies) - y) .^2, 1);

Error in test (line 22)
        d = disteu(v, code{l});

Error in main (line 4)
   test('C:\Users\Antonio\Documents\MATLAB\test\',5, code);

Just for the sake of clarity I have attached my code.

Could anyone help me please?

Hi Antonio,

Here in the disteu file (line 43)

d(n,:) = sum((x(:, n+copies) - y) .^2, 1); 

dimensions of x(:,n+copies) and y do not match, rows in x are 21+M whereas rows in y are 0+M2.

• You may refer the padarray doc.
• You may replace your code from line 21 to 34 in disteu file by this:

if (M < M2) 
x = padarray(x,M2-M,0,'post'); 
[M, N] = size(x) 
else 
y = padarray(y,M-M2,0,'post'); 
[M2, P] = size(y) 
end
