A gap exists in voice coding technology between 2400 bit per second (bps) Linear Predictive Coding (LPC) voice coders and high quality coders at 9600 bps. Recently Code Excited Linear Prediction (CELP) coding has been proposed as a means of accomplishing high voice quality at 4800 pbs. However the CELP structure is a rather high complexity voice coder, and the underlying speech information which is actually being encoded by a CELP coder is non-obvious. This paper presents an approach for achieving high quality speech coding at 4800 mps with dramatically lower computational complexity using a Modified Residual Excited LPC (MRELP) coder. Major principles for high quality residual coding are set forth.
