Abstract
tAn analytical study of cepstral peak prominence (CPP) is presented, intended to provide an insight intoits meaning and relation with voice perturbation parameters. To carry out this analysis, a parametricapproach is adopted in which voice production is modelled using the traditional source-filter model andthe first cepstral peak is assumed to have Gaussian shape. It is concluded that the meaning of CPP is verysimilar to that of the first rahmonic and some insights are provided on its dependence with fundamentalfrequency and vocal tract resonances. It is further shown that CPP integrates measures of voice waveformand periodicity perturbations, be them either amplitude, frequency or noise.
