We present a novel Computer-Assisted Language Learning (CALL) system for Japanese students who learn English as a second language. We regard formant structure of Japanese vowels pronounced by Japanese learners of English as their own formant structure. This structure is transformed to learnerís ideal English formant structure based on the relationship between English and Japanese articulation charts both of which are corresponded with formant structure. When the learnersí English pronunciation is input, it is compared with the estimated ideal one, and articulatory instructions are given. We verified that the mapping and estimation of English vowel parameters are correct with bilingual speakersí speech and observed the learning effect with five students who tried the system.
