ABSTRACT: In order to get a better understanding of diphthongs, as Deterding (2000)
and Salbrina (2006) stated, the formant movement can be studied using the rate
of change (ROC). Current research has considered the ROC of diphthongs in
Kermanshahi Kurdish dialect. In this research, 840 tokens have been considered
from speech samples of 20 male/female speakers in word/sentence context. The
ROC of the first formant frequency (F1) and the second formant frequency (F2) is
studied using Praat version 5.2.34. The results show that F1 has the most
formant movement in /au/ and F1 in /ɑu/,
/ɑi/ has the least formant movement; also, in F2, the vowels of /ɑu/ and /ɑi/
show the most and least, respectively. Moreover, the ROC values are more in
word context than sentence context.
