Applying hamming window and pre-emphasis filter on speech signal in frame by frame analyzing

I am working on speech signals.I want to add hamming window and pre-emphasis filter on my speech signal. Here What I built. [ip] = audioread('D:\chant_1.wav'); fs=44100; t=(0:length(ip)-1)/fs; plot(t,ip); frame_duration=0.01; N=length(ip); frame_length=frame_duration*fs;

dir =['D:\Simulation_data\']; cd(dir)

for k=1:num_frames frame=ip((k-1)*frame_length+ 1 : frame_length*k);

    %Window the speech segment using a Hamming window.
     xi = frame.*hamming(length(frame))

     %Get linear prediction filer
     ncoeff=2+fs/1000;
     eq=lpc(frame,ncoeff); 
     [h,f]=freqz(1,eq,512,fs);
     r=roots(eq);
     r=r(imag(r)>0.01);
     ffreq=sort(atan2(imag(r),real(r))*fs/(2*pi));
     length(ffreq);
     fid = fopen('f5 chant.dat','at');
     for j=6 

         fprintf(fid,'%6.8f\n',ffreq(j)) ;       
     end
     fclose(fid) ;
    end

Thank you
