ABSTRACT
The goal of speech coding is to represent speech in digital form with as few bits as possible while maintaining the intelligibility and quality required for the particular application. Interest in speech coding is motivated by the evolution to digital communications and the requirement to minimize bit rate, and hence, conserve bandwidth. There is always a trade-off between lowering the bit rate and maintaining the delivered voice quality and intelligibility; however, depending on the application, many other constraints must also be considered, such as complexity, delay, and performance with bit errors or packet losses [1].
