The perception–production link varies with stages of L2 development and vowel properties

Abstract This study investigates whether the perception–production link in phonological acquisition varies with stages of L2 development. It also examines whether the perception–production link for L2 vowels varies according to vowel properties, or whether the L2 vowels match or mismatch with L1 vowels. Korean learners of English in the UK were divided into more experienced and less experienced groups based on age of arrival and length of residence. The learners completed English vowel production, English vowel identification, and English–Korean vowel mapping tasks with English words (e.g., beat, bot). The intelligibility of their production and the accuracy of their vowel identification were assessed. Results show that only the more experienced learners’ perception and production were significantly correlated. Among L2 Standard Southern British English vowels similar to L1 Korean vowels (/i, ʌ, u/) only /i/ showed a significant correlation between perception and production, while among L2 vowels dissimilar to L1 vowels (/eɪ, ɘʊ, ɑ, ɒ/) only /ɑ/ showed a negative correlation, indicating that the correlation varied with vowel properties. The study contributes to the L2 phonological acquisition literature by exploring the perception–production link in terms of different stages of L2 development and L2 vowel properties.
