Abstract

Line Spectral Pair information is routinely generated by speech coders, and transmitted to convey vocal tract information for reconstruction of speech. Quantization of these parameters is necessary to reduce bitrate, but causes a degradation in quality. Many quantization schemes quantize a differential value - either using a temporal or a frequency basis. Although neither scheme is shown to have significant performance advantages for LSP quantization through results presented here, both relate differently to speech content. Therefore this paper proposes an adaptive quantizer switching method using both bases, and assesses the advantages of such a switching scheme based on a number of common distance measures.
