A Cepstrum-Based Technique for Determining a Harmonics-to-Noise Ratio in Speech Signals.

de Krom, Guus

Journal of Speech and Hearing Research, v36 n2 p254-66 Apr 1993

A new method to calculate a spectral harmonics-to-noise (HNR) ratio is presented. The method discriminates between harmonic and noise energy in the magnitude spectrum by means of a comb-filtering operation in the cepstrum domain. HNR is seen to be a useful parameter in the analysis of voice quality. (Author/DB)
