Practical Use of Autonomous English Pronunciation Learning System for Japanese Students

We have developed an original CALL system designed to detect and diagnose English pronunciation errors in Japanese learners’ speech. We have begun using the system in an English class at Kyoto University in Kyoto, Japan. The class consists of approximately 40 students, and the students have practiced pronunciation using this system on four separate occasions. Sixty minutes was allocated for each practice session, providing a total of 9600 minutes of practice time per academic calender year. We have examined the recorded speech data and corresponding speech recognition results obtained for the first semester of the preceeding academic year.
