음향자질 분석을 통해 본 단기 자가교정 효과: 영어 유성구개치경마찰음을 중심으로

Abstract

This study discusses whether Korean speakers improved their pronunciation of the English voiced alveopalatal fricative /ʒ/ by listening to an English speaker's pronunciation and self-correcting their pronunciation of it. Korean does not have this consonant in its phonemic inventory. However, since a voiceless counterpart to it is found in Korean as an allophone of the , Korean speakers may produce it as a voiceless consonant due to L1 transfer. In addition, previous studies reported that Korean alveopalatal consonants were in fact alveolar consonants. Thus, Koreans may produce it as an alveolar fricative. To investigate these possibilities, its acoustic properties were analyzed in terms of frication noise durations, spectral peak locations, and spectral moments. The statistical results showed that the Koreans did not produce a voiceless alveolar fricative after the self-correction but produced a fricative that was closer to the voiced alveopalatal fricative. The Koreans' and the English speakers' productions of it shared the characteristics of some acoustic properties.
