Abstract
The MELP algorithm was standardized by the USA Department of Defense in 1997. The MELP algorithm features less complexity than the CELP algorithm with comparable output speech quality at half 2.4 kbit/s. This paper presents an implementation of a 2.4 kbit/s mixed excitation linear prediction speech coder using the TMS320C44 digital signal processor. The emphasis is on exploiting the DSP platform
