This study aims to investigate the acoustic cues for the perception of English /s/ in word-initial and word-final positions by Korean listeners. We conducted a perception experiment to find the crucial acoustic cues which determine the mapping between English /s/ and the corresponding Korean loan sounds. The stimuli for the identification experiment were manipulated according to the frication duration of /s/, the prosodic position of /s/, and the stresshood of the syllable containing /s/. Korean listeners listened to each stimulus and identified it as Korean [s] or [s’]. Two main results were found. First, Korean listeners perceive English word-initial /s/ as Korean [s’] regardless of the duration of /s/ when it belongs to a stressed syllable. However, English word-initial /s/ belonging to an unstressed syllable is perceived as either [s] or [s’] depending on /s/ frication duration. Second, the perception of English word-final /s/ is not affected by stress but by the duration of /s/. Perception of English word-final /s/ exhibits a length effect in that English word-final /s/ is perceived differently based on its distance from the word-initial position. The results are discussed in light of prosodic domain strengthening and the relation between speech perception and loanword adaptation.
Abstract
This study aims to investigate the acoustic cues for the perception of English /s/ in word-initial and word-final positions by Korean listeners. We conducted a perception experiment to find the crucial acoustic cues which determine the mapping between English /s/ and the corresponding Korean loan sounds. The stimuli for the identification experiment were manipulated according to the frication duration of /s/, the prosodic position of /s/, and the stresshood of the syllable containing /s/. Korean listeners listened to each stimulus and identified it as Korean [s] or [s’]. Two main results were found. First, Korean listeners perceive English word-initial /s/ as Korean [s’] regardless of the duration of /s/ when it belongs to a stressed syllable. However, English word-initial /s/ belonging to an unstressed syllable is perceived as either [s] or [s’] depending on /s/ frication duration. Second, the perception of English word-final /s/ is not affected by stress but by the duration of /s/. Perception of English word-final /s/ exhibits a length effect in that English word-final /s/ is perceived differently based on its distance from the word-initial position. The results are discussed in light of prosodic domain strengthening and the relation between speech perception and loanword adaptation.
