what is the matlab code to remove noise from the speech signal?

clc;
clear all;
close all;
fileName='1.wav';
[x, fs] = wavread(fileName); 
N = length(x);
t=(0:length(x)-1)/fs;

% Original Speech
figure(1);
set(gca, 'FontName', 'Times New Roman', 'FontSize', 10);
plot(t,x);
title('Original Speech');
xlabel('Time(s)');
ylabel('Amplitude(dB)');

Hi! As far, as i know, there is no built-in functions. But, who knows. You can use wavelet transform for denoising.
