한국인 학습자의 일본어 어두 유성파열음의 발음 습득 실태 : 자발(회화) 음성의 VOT를 중심으로

Abstract

This study describes the acquisition status of Japanese initial voiced plosive of Korean learners using spontaneous speech, the descriptive contents and the pronunciation teaching method of Japanese initial voiced plosive’s VOT in commercial Japanese voice textbooks. As a result, the following findings were confirmed.BR First, most of Korean learners were acquiring Japanese initial voiced plosive as +VOT. The longest +VOT value appears in the phonetic environment where the point of articulation is the soft palate and the subsequent vowel is /i/ whereas the longest -VOT value appears when the point of articulation is the alveolar ridge and the subsequent vowel is /e/.BR Second, the VOT value of Japanese initial voiced plosive by both Korean learners and Japanese speakers is most distributed in common in the range of 0ms to 50ms , but in terms of the proportion , Korean learners’ VOT values were higher than Japanese speakers`.BR Third, commercial Japanese voice textbooks describe Japanese initial voiced plosive as -VOT, and suggest learners pronounce it by adding ‘ん’ or a vowel before the voiced stop. But, it is necessary to modify and complement the explanation and the pronunciation teaching method of VOT considering the fact that +VOT appears in the pronunciation of most Japanese speakers and Korean learners, and it is also necessary to examine the validity and the need for improvement of existing pronunciation teaching methods.
