Abstract
The present work gives a proposed method of sampling speech signals with a nonuniform sampling rate according to the magnitude of the slope of the signal, provided that the average sampling rate satisfies Shannon´s requirements. With this proposed method, the quality of the reconstructed speech signal is improved. Experimental results have been compared with those obtained mathematically, and satisfactory agreement is indicated.
