RD-19,333 HYBRID SWITCHED MULTI-PULSE/STOCHASTIC SPEECH CODING TECHNIQUE ABSTRACT OF THE DISCLOSURE Improved unvoiced speech performance problem in low-rate multi-pulse coders is achieved by employing a multi-pulse architecture that is simple in implementation but with an output quality comparable to code excited linear predictive (CELP) coding. A hybrid architecture is provided in which a stochastic excitation model that is used during unvoiced speech is also capable of modeling voiced speech by use of random codebook excitation. A modified method for calculating the gain during stochastic excitation is also provided. |
