Abstract :
The paper uses the wavelet packet bandpass filter as speech recognition front-end processor and presents the wavelet frequency band partition methods based on Bark scale and ERB scale, which are used in a practical speech recognition system. The results show that the method based on ERB scale is better than one based on Bark.
