  • Enhanced quantization method for spectral frequency coding
    Patent number: 6487527
    Abstract: A linear predictive speech encoding method combines vector quantization with the search for roots of LSP polynomials. At Under this method, a code book searchable using line spectral pair (LSP) values is created from a line spectral frequency (LSF) code book, thus ensuring linear distortion performance without the costly run-time complexity of finding roots to high-order LSP polynomials in the LSF domain.
