2000 Differential coding of speech LSF parameters using hybrid vector quantization and bidirectional prediction
abstract
This article presents a new strategy to encode the LP (linear predictive) short-time spectral envelope (STSE) of speech. A better reconstruction of the STSE is achieved by modifying the usual trade-off between the transmission rate of the LP parameters and the performance of the quantization algorithm. A differential coding based on bidirectional prediction and hybrid vector quantization is used to compensate the increase in transmission rate. Simulation results show the effectiveness of this coding strategy.

1995 A modified CELP model with computationally efficient adaptive codebook search
abstract
In this letter, we propose a CELP algorithm in which the complexity of the search procedure in the adaptive codebook is greatly reduced. This is achieved by means of a modified model of the CELP synthesizer, while keeping the usual perceptual weighting of the synthesis error in the analysis procedure. Simulation results show that the proposed algorithm can provide speech quality comparable to the one obtained with the conventional CELP codec.>
