유음의 비음화 저지 현상과 형태 인식

Abstract

The purpose of this study is to examine the realization patterns of /ㄹ/ nasalization in standard Korean speakers and identify the factors influencing the realization of this phonological phenomenon. To achieve this goal, a total of 30 male and female speakers in their 20s, born and residing in the Seoul, Gyeonggi, and Incheon regions, were asked to read sentences containing 60 experimental data that could observe /ㄹ/ nasalization. The analysis revealed diverse patterns of /ㄹ/ nasalization realization depending on the speaker and the word. Only two speakers applied /ㄹ/ nasalization to all words, and female speakers often pronounced 'ㄹ' without nasalization, maintaining the original spelling. Additionally, it was observed that /ㄹ/ nasalization was less applied when 'ㄹ' was followed by a monophthong compared to when it was followed by a diphthong. Through this research, it was confirmed that the phenomenon of /ㄹ/ nasalization, considered a obligatory phonological phenomenon of Korean, exhibits variation among younger speaker groups. It also suggests that young speakers consciously make efforts to preserve /ㄹ/ in their pronunciation.
