What does cepstral Peak Prominence measure?

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 does a low cepstral peak prominence mean?

Cepstral Peak Prominence (CPP) is an acoustic measure of dysphonia recommended by an ASHA expert panel. A lower CPP value is associated with a more dysphonic voice.

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.

What is cepstral spectral index of dysphonia?

The cepstral and spectral index of dysphonia (CSID) quantifies the level of voice abnormality, and is derived from the CPP, L/H ratio, and sex information through weighted multiple regression. The CSID tends to increase as the severity of voice disorders increases.
