Abstract
The performance of several algorithms for the quantization of the line spectrum pair (LSP) parameters is studied. An adaptive method which utilizes the ordering property of the LSP parameters is presented. The performance of the different quantization schemes is studied on a long sequence of speech samples. For the spectral distortion measure, appropriate performance comparisons between the different quantization schemes are rendered. Experimental results indicate that high-quality synthesized speech can be obtained using the LSP parameters at relatively low rates.
