The Frequency Domain Analysis of Speech Signals Based on MATLAB

Abstract:

Frequency domain analysis of speech signal includes spectrum analysis, power spectrum and the inverse spectrum, spectral envelope analysis. The common methods of frequency domain analysis includes bandpass filters , Fourier transform, linear see method etc.. Using MATLAB discusses the short section of the speech signal spectrum, cepstrum and complex spectrum, the pitch and formant simulation results are given.
