Abstract

This study investigates the effect of Japanese (L1) on the production of the Korean rhythmic structure. Korean and Japanese have typologically different rhythmic structure as a syllable-timed language and mora-timed language, respectively. This rhythmic difference comes from the different phonological properties of the two languages. Due to this difference, Japanese speakers that are learning Korean may produce a different rhythm than native Korean speakers' rhythm. To investigate the influence of the native language's rhythm on the target language, we conducted an acoustic analysis using acoustic metrics such as %V, VarcoV, and VarcoS. Four Korean native speakers and ten advanced Japanese Korean learners participated in a production test. The analyzed material consisted of six Korean sentences that contained various syllable structures. The results showed that KS and JS's rhythms are different in %V as well as in VarcoV. In the case of VarcoS, significant rhythmic difference was observed in the VC and CVC syllable, in which the coda segment is nasal sound. This study allowed us to observe the influence of L1 on production of L2 rhythm.
