言語変異の地理的差異(<特集>音声のバリエーション)

抄録

This article is a comparative sociolinguistic study of a sound change in Japanese: denasalization of velar nasal. Hibiya (1988) and Miyanaga and Matsuda (2001a, b) applied the methods of variationist sociolinguistics to spontaneous speech data collected in the cities of Tokyo and Takasago, Hyogo, respectively. Quantitative results derived from these two studies form the basis of comparison. We find that the variable process of velar nasal exhibits a remarkable similarity in both regional dialects.
