This study explores the characteristics of Indonesian oral monophthong vowels produced by male and female language consultants in Banda Aceh, Indonesia, as their first language. Using purposive sampling, ten Acehnese males and ten Acehnese females were selected to articulate eight target vowels: /i/, /e/, /ɛ/, /ә/, /a/, /u/, /o/, and /ɔ/. Vowel measurements were obtained through recorded word elicitation, using a word list containing the target vowels. F1 and F2 frequencies in Hertz were determined and analyzed using Praat software to assess vowel qualities and subsequently converted to the Bark scale. Vowels were plotted on the F1/F2 formant space. The findings illustrate the distinct measurements of each Indonesian monophthong vowel by male and female consultants, represented in the vowel space. Male vowels generally exhibit higher and more centralized positioning, while female vowels appear more dispersed and lower. This research contributes valuable insights for comparing vowel systems across various languages and dialects spoken in multilingual Indonesia.
