Description: Into the experimental interface, press " input speech signal" button, input speech signal data. Spectral analysis of the data, given the speech signal waveform and frequency spectrum. Set the system' s cutoff frequency, select a given type of system, the establishment of the system function, and draw the frequency response of the system diagram. 5 of speech signal spectrum by multiplying the filter response (i.e., the voice signal is high, the low-pass filter), to obtain the spectrum of the output signal, the result after the inverse Fourier transform function into a time domain signal plot Processing After the signal waveform, and were filed.
