CSID_SCOREnumber

number - CSID score (154.59 − 10.393·CPP − 1.083·SR − 3.713·SR_SD).

CPPnumber

number - Smoothed cepstral peak prominence over the whole signal, in dB.

SRnumber

number - Low/high spectral ratio (energy below 4 kHz vs 4–8 kHz), in dB, averaged over voiced frames.

SR_SDnumber

number - Standard deviation of the spectral ratio across voiced frames, in dB.

N_VOICED_FRAMESinteger

integer - Number of voiced frames used.
