Abstract (in Japanese) (See Japanese page) 
(in English) We have developed the pronunciation practice CAI system called "Lip Readingあい" for deaf children. This system is based on bimodality of human speech and lip reading techniques. It enables a learner to practice pronunciation by looking at a model speaker's mouth movements, and allows him/her to compare them with his/her own mouth movements. A video camera connected to the computer simultaneously shows the mouth movements of the model speaker and those of the learner’s own, so that the learner can compare mouth movements. This system also provides a study unit to practice pronunciation by looking at computer graphics animation of mouth movements of the model speaker. In order to evaluate the effectiveness of the CAI system by using CG animation, Japanese vowel and consonant sounds were read by a group of Japanese students. Their mouth movements before and after practicing with the CAI system were videotaped and evaluated. The rate of correctly perceived mouth movements was 11% greater after practicing with the system than that without practicing.
