Abstract :
This paper presents an efficient low-delay CELP speech coder based on a structure given by Chen et el. (1992). The proposed coder can operate at a rate of 8 Kb/s and has an arithmetic complexity that is 20% lower than that of the CELP of Chen et al. with an acceptable increase in the delay. The proposed coder has been tested to provide a good-quality speech
