What is cepstral peak prominence

Cepstral peak prominence (CPP) is an acoustic measure of voice quality that has been qualified as the most promising and perhaps robust acoustic measure of dysphonia severity [1].

What is cepstral Peak Prominence smoothed?

A CPP variation is called cepstral peak prominence-smoothed (CPPs) and has different calculation algorithms, such as smoothing the cepstrum before extracting the peak and using 1024 frames every 2 ms instead of 10 ms, which makes CPPs more robust and with no influence of artifacts [15].

What is cepstral analysis of speech?

The Cepstral Analysis is a tool for detecting periodicity in the frequency spectrum and it is mainly used in pitch detection, radar and sonar applications, speech analysis, and diagnostics.

What are the units for cepstral Peak Prominence?

The height (i.e., “prominence”) of that peak relative to a regression line through the overall cepstrum is called the “cepstral peak prominence” or CPP and is typically reported in units of decibels.

What does Cpps measure?

Smoothed cepstral peak prominence (CPPS) has been touted as a robust overall measure of dysphonic voice characteristics in single vowel and connected-speech tasks.
