Abstract
The line spectral pair (LSP) conveys vocal tract information for reconstruction of speech in an analysis-synthesis speech coding system. Quantization of LSP parameters is necessary to reduce bit-rate, but causes unavoidable degradation in quality. This paper proposes an adaptive quantization method to reduce bit-rate whilst maintaining reasonable speech quality. The method exploits the relationship between LSP position and speech features
