Summary :

The present paper describes a quality enhancement of band-limited speech signals. In regular telephone communication, the quality of the received speech signal is degraded by band limitation. We propose an effective but simple scheme for obtaining narrowband speech signals in which the frequency components are estimated from band limited signals. The proposed method utilizes aliasing components generated by wavelet reconstruction filters in the inverse discrete wavelet transform. The results of enhancement have been verified by applying this method to speech samples via telephone lines to obtain a noticeable improvement in speech quality.
