Abstract :
A simplified soft-bit speech decoding (SBSD) algorithm is proposed and is used in decoding the encoded speech parameters from the mixed excitation linear prediction (MELP) coder. Simulation results show that the simplified algorithm can reduce significantly the decoding complexity and memory requirement of SBSD at a slight penalty of a marginal drop in performance.
