How Different are Vowel Epentheses in Learner Speech and Loanword Phonology?

Abstract
Difference of learner speech and loanword phonology is investigated in terms of Korean learners¡¯ speech and their loanword adaptation of English words with a post-vocalic word-final stop. When we compared the speech of 12 Korean learners in mid-intermediate level with that of eight English speakers, the learner speech did not reflect loanword phonology of the vowel insertion after a voiced word-final stop (e.g., rib[?], bad[?], gag[?] vs. tip[=], cat[=], book[=]),
but, instead, the target phonology of vowel lengthening before a voiced word-final stop (e.g., rib[r?:b], CAD[k©¡:d], bag[b©¡:g] vs. rip[r?p], cat[k©¡t], back[b©¡k]). A longitudinal study of learner speech before and after instruction showed some development toward the acquisition of target phonology. The results indicate that learner speech departs from loanword phonology, and approaches to target speech in a faster rate than direct ratio. Thus, native phonology predicts loanword phonology, but lends little support to learner speech. Our results also indicate that loanword phonology is constant, while learner speech changes toward the acquisition of target phonology.
