Abstract :
The authors show that for small errors in an LPC model, spectral distortion and weighted squared distortion measures in the coefficients of arbitrary one-to-one transformations of the LPC parameters are equivalent. For line spectrum pairs and immittance spectrum pairs, the weighting matrix is diagonal, which is advantageous for efficient quantisation
