홀소리 길이의 늘어짐(Vowel lengthening)의 기능 및 형태음운론적 해석

A Study on the Vowel lengthening and a Morphophonological Interpretatipon for its function

The aim of this paper is to analyze the vowel lengthening in Korean, whose function is distinctive in the word's level. In this paper, I examined two acoustic parameters : vowel length and formants(F1 and F2) to distinguish or to identify the long vowel and his short correspondant, for exemple, /a:/ and /a/. According to the results of experimental analysis and to the discussion on the vowel length's relation and its influence to Korean phonological system, I considered a vowel lengthening as a prosodeme, so as a prosodic element in Korean phonological system.
