Abstract
Low bit rate speech coding techniques and a new coding scheme for vocal
tract parameters are presented. Linear prediction based voice coding techniques
(linear predictive coding and code excited linear predictive coding) are
examined and implemented. A new interframe differential coding scheme for
line spectrum pairs is developed. The new scheme reduces the spectral distortion
of the linear predictive filter while maintaining a high compression ratio.
