Write a Matlab program for speech de-noising. Add Additive White Gaussian Noise (AWGN) to clean speech signal. Analyze the plot of noisy speech by finding its Power Spectral Density (PSD). Apply Gaussian filter to noisy speech and examine the result obtained. How Gaussian filter de-noise the signal? Give brief explanation.

Write a Matlab program to:

(a) Read clean speech signal

(b) Run and listen clean speech signal

(d) Add White Gaussian Noise to speech signal

(e) Run and Listen noisy speech signal (0 Plot clean speech signal and noisy speech signal using subplot command

(g) Find Signal to Noise Ratio of noisy speech
