Abstract (in Japanese) (See Japanese page) 
(in English) Speech communication induces inevitable variations of speech acoustics due to differences in speakers, microphones, etc. Recently, a novel acoustic representation of speech was proposed where these variations were effectively suppressed. In other words, the dimensions indicating the variations were mathematically removed. Using the new structural representation for CALL, automatic evaluation of the pronunciation was investigated. In this study, some correlation analysis is done using the vowel charts of the individual learners plotted by an expert researcher of English phonetics. Further, an improved method of estimating the vowel correction priority is devised.
