The Assimilation of L2 Australian English Vowels to L1 Japanese Vowel Categories: Vocabulary Size Matters

摘要

Theory strongly suggests that L2 perception is influenced by the LI. More recently, it has also been proposed that L2 vocabulary size may be related to the perception of non-native phones. Japanese (JP) learners of Australian English (AE) identified AE vowels using JP vowel categories and provided goodness-of-fit ratings. Results show systematic perceptual assimilations of L2 to L1 vowels and learners with a larger L2 vocabulary provided more consistent identifications.
