This research looks into a component of language in foreign language learning and teaching - pronunciation instruction and acquisition - and presents that computer-based training using sound visualization technique can be effectively implemented to Korean EFL learners to produce and perceive English pitch and durational contrast for words in sentences as well as for words in isolation. Training using sound visualization technique can be effective in improving second language learners’ perceptions and productions of segmental and suprasegmental speech contrasts. This study assessed the efficacy of a pronunciation training that provided visual feedback for EFL learners acquiring pitch and durational contrasts to produce and perceive English phonemic distinctions. The subjects’ ability to produce and to perceive novel English words was tested in two contexts before and after training; words in isolation and words in sentences. The findings support the feasibility of learner-centered programs using sound visualization technique for English language pronunciation instruction. (Kongju University)
