Abstract
The present invention is a method for determining linear predictive coding filter parameters for encoding a voice signal. The method includes sampling a voice signal grouping the samples into a plurality of frames generating a plurality of reflection coefficients for each frame of samples quantizing the reflection coefficients generating spectral coefficients from the quantized reflection coefficients selecting a quantized reflection coefficient having the smallest log-spectral distance between a quantized spectrum and an unquantized spectrum and converting the selected quantized reflection coefficient to linear predictive coding (LPC) filter coefficient.
