摘要
Abstract
By the time-frequency analytic feature of wavelet transformation, the appropriate wavelet functions are selected to strengthen, to code, to compress and to extract signal features of speech according to the characteristics of the speech signals. Simulated by Matlab, the strengthened signals, the compression ratio parameter, the energy reservation parameter, the zero coefficient parameter and the speech signal features were obtained. The results show that the speech signal processing based on wavelet transformation exhibits good characteristics.关键词
