A Fundamental Phonetic Investigation of Korean Vowels

The purpose of this study was to investigate and quantitatively describe the acoustic characteristics of current Korean monophthongs. Recordings were made of 33 men and 27 women producing the vowels /i, e, ${\varepsilon}$, a, (표현불가), O, u, (표현불가)/ in a carrier phrase "This character is _." A listening test was conducted in which 19 participants judged each vowel. F1, F2, and F3 were measured from the vowels judged as intended vowels by more than 17 people from the listening test. Analysis of formant data shows some interesting results including the undeniable confirmation of 7-vowel system in current Korean.
