Analysis of Speech Signals Using MATLAB
The speech signal processing is the cross-discipline which combines the voice science with the digital signal processing technology. The voice is taken as a special signal, i.e. a complex vector. By using the command functions in the digital signal processing tool-MATLAB, the digital signal processing can solve many problems. The spectrum of voice signals are analyzed, which is the same as the spectrum analysis of common signals. A variety of digital filters (FIR low-pass filters, high pass filters, band-pass filter and IIR band stop filter) are used to filter and analyze the voice, and the voice signals are compared with the original signal. Finally, the conclusion is drawn.
