This study examined whether learning context and language aptitude affected the use of pronunciation learning strategies and pronunciation proficiency. One hundred thirty-eight Chinese learners (88 KFL Ss & 50 KSL Ss) learners were investigated for the correlation between learning context(KSL, KFL), language aptitude (high/low), pronunciation learning strategy and pronunciation proficiency. Participants' sound discrimination ability was measured by PLAB and then they were divided into high group (upper 30%) and low group (lower 30%) by scores. SPLS and personal information survey were also conducted. The results showed that (i) a significant difference was found in pronunciation proficiency pursuant to learning context and language aptitude, (ii) use of pronunciation learning strategy differed significantly pursuant to learning context and language aptitude, and (ⅲ) use of pronunciation learning strategy could predict pronunciation proficiency. The findings suggest that effective pronunciation learning strategy should be investigated and taught in L2 Korean classroom.
