Cepstral peak prominence: A comprehensive analysis
6 An analytical study of cepstral peak prominence (CPP) is presented, intended to provide an insight into its meaning and relation with voice perturbation parameters. To carry out this analysis, a parametric approach is adopted in which voice production is modelled using the traditional source-filter model and the first cepstral peak is assumed to have Gaussian shape. It is concluded that the m...
متن کاملProperties of the cepstral peak prominence and its usefulness in vocal quality measurements
Unlike many acoustic measures, Cepstral Peak Prominence (CPP) has shown consistently high correlations with subjective vocal quality ratings. However, this superiority of the CPP index is reported based on empirical results, with its theoretical advantages not always clearly stated. In this paper the properties of the CPP which makes it a good predictor for vocal quality are addressed, as well ...
متن کاملThe relationship between cepstral peak prominence and selected parameters of dysphonia.
Traditional measures of dysphonia vary in their reliability and in their correlations with perceptions of grade. Measurements of cepstral peak prominence (CPP) have been shown to correlate well with perceptions of breathiness. Because it is a measure of periodicity, CPP should also predict roughness. The ability of CPP and other acoustic measures to predict overall dysphonia and the subcategori...
متن کاملSpectral Peak-Weighted Liftering of Cepstral Coefficients for Speech Recognition
In this paper, we propose a peak-weighted cepstral lifter (PWL) for enhancing the spectral peaks of an all-pole model spectrum in the cepstral domain. The design parameter of the PWL is the degree of pole enhancement or pole shifting toward the unit circle. The optimal pole shifting factor is chosen by considering the sensitivity to spectral resonance peaks, the variability of cepstral variance...
متن کاملThe Study of Vocal Function in Patients With Early Laryngeal Carcinoma After Transoral Laser Microsurgery
Objective Today transoral laser microsurgery is considered as one of the first options to control early laryngeal cancer, and voice disorder is one of the inevitable complications of this therapeutic component. This study aimed to compare the vocal function in patients with early-stage laryngeal cancer following laser surgery with healthy individuals with normal voice quality using acoustic ana...
