record voice matlab

hello everyone
I am asking for how to use matlab to enter a voice signal ,
and how to make a matlab code to modulate and demodulate this signal using AM or FM modulation

I need every help from you pals
 

If you have the Signal Processing Toolbox, try this:

% Record from microphone, modulate it, demodulate it, then playback everything
input = wavrecord(44100,44100);
am_mod = modulate(input,5000,44100,'amdsb-tc');
fm_mod = modulate(input,5000,44100,'fm');
am_demod = demod(am_mod,5000,44100,'amdsb-tc');
fm_demod = demod(fm_mod,5000,44100,'fm');
wavplay(input,44100);
wavplay(am_mod,44100);
wavplay(fm_mod,44100);
wavplay(am_demod,44100);
wavplay(fm_demod,44100);
 

Re: I am asking for how to use matlab to enter a voice signa

thanks very much very much ,
but I want how to record the voice signal from the microphone in matlab as a matrix
and modulate it using mathematical procedures and plot every signal in the modulation process
