Title: Speech Signal Processing by Digital Filter Based on MATLAB
Abstract: Time-domain waveform and frequency spectrum of the recorded speech signals are analyzed by sampling.The performance indexes of digital filters are given.Two methods of window function and bilinear transformation are used to design the digital filters.The speech signal is filtered by the filters,and then magnitude-frequency responses of the signal before and after filtering are received.The advantages of two digital filters in speech signal processing are demonstrated by comparing different methods for filtering simply and effectively.
