This paper describes the application of the wavelet packet transform for speech analysis. In particular, the paper compares the performance of the wavelet packet transform with that of both the discrete wavelet transform, and a cascade auditory model. A novel hybrid wavelet transform analysis method is proposed, which combines the best features of the discrete wavelet transform and the fast wavelet transform. Results are presented in the form of spectrogram plots.
