Description

This MATLAB exercise estimates the statistical properties of a speech signal, namely the speech Probability Density Function (PDF) (as estimated from a histogram of speech samples, suitably normalized), the speech power density spectrum (as estimated using the method of modified periodograms), and the speech autocorrelation (obtained as the inverse discrete-time Fourier transform of the speech power density spectrum).
