Number of Pauses in the praat file

[Delara-Forghani]

Hello,
I just wanted to know how detecting the number of pauses works in myspsolution.praat? As I read the file I found that the "npause" variable was considered as the number of "sounding" rows instead of "silent". Could you please explain why it counts the number of pauses and fillers?
Thanks,

The acoustic characteristics of filled pauses include duration, variation of F0 , the height of F0, variability in formants F1 through F3, and overall stability. Filled pauses, in contrast to other syllables, tend to have longer durations, show less F0-variation, have a lower F0, and less F1-F3 variability. Filled pauses tend to be long, stable syllables pronounced at a low pitch. Additionally, filled pauses are usually pronounced as a schwa . For American English the sound of the filled pause may be closer to a mid-open back unrounded vowel ([ʌ]). As far as salient pauses are concerned, an empirical study on human transcripts of the speech recordings showed silent pausing would have a threshold of 250 ms.
