ABSTRACT
The distinctive feature of wavelet transforms applications it is used in speech signals. Some problem are produced in speech signals their synthesis, analysis compression and classification. A method being evaluated uses wavelets for speech analysis and synthesis distinguishing between voiced and unvoiced speech, determining pitch, and methods for choosing optimum wavelets for speech compression are discussed. This comparative perception results that are obtained by listening to the synthesized speech using both scalar and vector quantized wavelet parameters are reported in this paper.
