We describe in this paper a code-excited linear predictive coder in which the optimum innovation sequence is selected from a code book of stored sequences to optimize a given fidelity criterion. [] Key Result Our results indicate that a random code book has a slight speech quality advantage at low bit rates. Examples of speech produced by the above method will be played at the conference.

Two new speech coding algorithms - multi-pulse LPC and stochastic coding (code-excited linear prediction) - have been proposed recently to achieve high quality speech at bit rates below 10 kbits/sec.

Pitch Modelling for Speech Coding at 4.8 kbitsls

The first new approach in this work is to use a pseudo-three-tap pitch filter with one or two degrees of freedom of the predictor coefficients, which gives a better quality reconstructed speech and also a more desirable frequency response than a one-Tap pitch prediction filter.

A method to reduce the excitation coding bit rate is proposed and a search method for the LTP index is developed that takes into account the number of innovation code words assigned to each LTPindex, in the search for an optimal LTP sequence.

A candidate algorithm for the new CCITT 16-kb/s speech coding standard is presented. This algorithm is based on backward-adaptive CELP (code-excited linear prediction) where the predictor and the

Tree Coding in a Code Excited Linear Predictive Speech Encoder

Decision coding together with noise masking theory is used in a code excited linear predictive speech roding system and high objective and subjective performance is obtained at low bit rates.

Low delay tree coding of speech at 8 kbit/s

A low delay tree coder for coding speech at 8 kbit/s that incorporates a new backward coefficient adaptation structure is presented, which produces good quality speech over ideal channels, and maintains robustness to bit errors for independent bit error rates up to and including 10/sup -2/.

A speech coder based on a single-pulse excitation code-excited linear predictive coding (SPE-CELP) model of linear-predictive coding (LPC) is proposed and it is concluded that the coder produces significantly better speech quality than LPC10E, though the synthesized speech still sounds slightly buzzy for certain speakers.
