Abstract

The objective of this work is to compare the energy rate of a level 3 speech signal using the discrete wavelet transform (DWT) of various mother wavelets such as Haar, Meyer, biorthogonal, Coiflets, Symlets, and Daubechies, to determine the range of values for both genders of the speaker. The speech signal is filtered by an 8th order Butterworth filter. We perform the discrete wavelet transform (DWT) on the mother wavelet to obtain the energy values of each mother wavelet at the third level of the decomposition for male and female speakers. We then compare the energy values of speech signals between men and women speaking the same sentence, This comparison is conducted on several databases containing repeated sentences for the same individual or both genders, the results are found to be acceptable for further analysis.
