Lee, Heedoo. (2015). Phonological change of the rising diphthongs and dispersion effects. The Linguistic Association of Korea Journal 23(4), 239-258. /jə/ and /ə/ after consonants were perceptually confused with each other in Middle Korean because the articulatory domain of /ə/ was placed in the front area of the phonetic vowel system and so was overlapped with the auditory domain of /jə/. For escaping this perceptual confusion the dispersion effects work here. Therefore the falling glide /j/ was inserted to the end of /jə/ in order to increase F2. As the result of the glide epenthesis, /jəj/ was maximally contrasted with /ə/ by the minimization of perceptual confusion and /jəj/ developed diachronically through the process of /jəj/>/je/>/e/. Also /jə/ has synchronically been alternated with /e/ by the dispersion effects in some dialects in which /jə/ is articulated in the front area. |
