  • Apparatus and quality enhancement algorithm for mixed excitation linear predictive (MELP) and other speech coders
    Patent number: 6453287
    Abstract: A system and method for enhancing the speech quality of the mixed excitation linear predictive (MELP) coder and other low bit-rate speech coders. The system and method employ a plosive analysis/synthesis method, which detects the frame containing a plosive signal, applies a simple model to synthesize the plosive signal, and adds the synthesized plosive to the coded speech. The system and method remains compatible with the existing MELP coder bit stream.
