hi,

The error occurs because y and z do not have the same length, try :

 [y,fs,nbits]=wavread('C:\Users\HP\Desktop\angel_48k_stereo.wav');
 [z,fs,nbits]=wavread('C:\Users\HP\Desktop\keyboard_48k.wav');
  ny=length(y);
  nz=length(z);
  N=min([ny nz]);
  Y=y(1:N);
  Z=z(1:N);
  signal=Y+Z;

do they have the same Fs?
