Production of coda voicing contrast of L2 English by native Mandarin Chinese speakers in comparison with native Korean speakers

This study investigates native language effects on phonetic encoding of coda voicing contrast in L2 English by Chinese versus Korean speakers. Results show much smaller phonetic differences in both vowel duration and F0 in marking coda voicing contrast for Chinese speakers than Korean speakers, despite native Chinese speakers' experience with lexical tones. They suggest that producing an F0-related cue in L2 is conditioned by position-specific phonological richness and use of F0 in the speaker's L1. The results are discussed in terms of contrast maximization and effort minimization with reference to the information structure occurring in both L1 and L2.
