This GD3110B Digital Language Laboratory System provides a facility which allows the student to listen to the right pronunciation, repeat and record the same, listen to their performance and compare with the set model, and do self-assessment. Since a digital language laboratory gives every learner of any language opportunity for self-development, it is flexible and does not necessarily require a teacher all the time, because the student can practice even without the teacher. At the same time, it is possible for teachers to provide assistance individually and collectively. The language laboratory allows every participant his or her privacy to speak and listen.
