An Instrumental Analysis of Acehnese Oral Vowels
摘要
This study is an instrumental analysis of Acehnese oral monophthongs and diphthongs. It is based on Asyik’s (1987) description of these vowels. Ten monophthongs and twelve diphthongs were produced by ten female North Aceh dialect speakers. The target vowels were placed in common words and were elicited with the aid of pictures and leading questions. A total of 660 tokens of the vowels were analyzed using PRAAT version 4.6.12 (Boersma & Weenink 2007). The results for the monophthongs generally support Asyik’s (1987) description of these vowels with the exception of /u/ and /ɔ/ which appeared to have advanced in the vowel space. For the diphthongs, there was a tendency for /ɛə/ to be realized as a long monophthong by the speakers, while some of the other diphthongs described by Asyik appeared to have different off-glides.
