This study investigates how Korean listeners’ sensitivity to the English tense-lax vowel contrast influences their perception of /ɨ/ epenthesis in English loanword adaptation in Korean. Native Korean listeners completed English tense-lax discrimination tests and an ABX perceptual task using English CVC nonce words that varied by vowel tenseness, final stop voicing, release, and place of articulation. The results showed that the perception of /ɨ/ epenthesis increased significantly when the final stop was released, voiced, or alveolar/velar. Although vowel tenseness alone did not yield a significant main effect, it interacted significantly with listeners’ tense-lax discrimination ability: participants with higher discrimination ability perceived /ɨ/ epenthesis more frequently when the vowel was tensed. This indicates that individual perceptual acuity modulates adaptation patterns in Korean. Specifically, the influence of vowel tenseness on /ɨ/ epenthesis is mediated by listeners’ sensitivity to the English tense-lax vowel contrast, underscoring the role of perceptual ability in shaping how non-native sounds are mapped onto native phonological structures.
