Number of Pauses in the praat file #25

Open Delara-Forghani opened 2 years ago

Delara-Forghani commented 2 years ago

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,

@Delara-Forghani it may be of help to you 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.
