Abstract :
We propose an approximation of the line spectral frequencies (LSFs) to the LPC cepstral coefficients (LPCCs). A direct relationship between LPCC and LSF is derived, and new parameters, named pseudo-cepstral coefficients, are obtained by reducing some factors in the relationship. We also address the statistical properties of the pseudo-cepstral coefficients and show their useful application to speech recognition
