Abstract

Computer-assisted oral drilling of a language needs not be limited to a language laboratory or a computer room any more. Lingua is developed to enable teachers to easily build oral drilling exercises for students to complete any time and any where on mobile devices. Students then choose to submit their best performance (recording) to the system for grading. As a self-learning tool, Lingua provides automatic computer-estimated scores on students’ recordings, which act as reference points for students to further practice. As a teaching tool, the system has a convenient grading area for teachers to easily listen to all submitted recordings and then give grades.
