English /s/ and Korean /sh/-/s*/ Contrast in Seoul and Busan Dialects: A Study of Category Solidity
Kang Kyoung-Ho

Abstract
The primary goal of the current study was to examine category solidity of Korean alveolar fricatives in the Busan and Seoul dialects of Korean. Considering the common belief of /sh/-/s*/ neutralization in Kyungsang speech, plain /sh/ and fortis /s*/ fricatives of Busan speakers were examined against the same fricatives of Seoul speakers. Perceptual distance between Korean /sh/ and /s*/ on the one hand and English /s/ on the other was investigated by use of across-linguistic mapping method. Two experiments of a perceptual mapping task of English /s/ to Korean /sh/ and /s*/ and a /s*/-production task were conducted on users of the Busan and Seoul dialects of Korean. The results from the perception and production experiments suggested that at a micro-level, younger Busan speakers have less solid category stability for Korean /s*/ compared with Seoul speakers, although their production of /sh/ and /s*/ was as highly distinctive from each other as that of Seoul speakers.
