项目摘要

This reports relates to the research and development of a student-led CALL system which is based upon the CAI (Computer Assisted Instruction) being firmly established in an educational site as an individual learning assisted system, has excellent operability, and enables pronouncing correction teaching.The developed CALL system has the following features ;1. A supplementation of audio information with visual information :Visual expression is one whose can be caught as an image and which has excellent memory. The student repetitively trains speaking and hearing information, the third party (teacher) evaluates the training result, and the evaluation result is fed back to the student by adding the voice data of the student to a visual symbol (tone symbol). This process enables the student to visually catch on objective pronouncing evaluation and deepen his understanding.2. Student-led type :For the conventional LL equipment, the teacher directly connects to students through switching operation and hears and evaluates the pronunciation of the student. This causes the student to be anxious or dissatisfied due to the interruption of the teacher, or the evaluation of an unacceptable pronunciation of the student.This system can be considered as a system where the student repetitively trains and understands the pronunciation, and thereafter requests the evaluation to the teacher to eliminate a learning anxiety.3. Learning and corrective teaching regardless of time and space :The voice data transmitted by the intention of the student is once stored into data-base. The teacher can correct the voice data and teach the student also out of school hours and the student can see the evaluation result from the data-base at any time. Then, the voice data transmitted by the student and the evaluation result are incorporated to a unity and presented to the student who can remember, regardless of an elapse of time, and reproduce the school situation at that time.

本报告是关于一个以学生为主导的CALL系统的研究和开发，该系统是基于CAI（计算机辅助教学）作为个人学习辅助系统在教育场所中牢固建立起来的，具有良好的可操作性，并能进行发音纠正教学。用视觉信息补充音频信息：视觉表达是一种可以作为图像捕捉的表达，具有良好的记忆力。学生重复训练说话和听力信息，第三方（教师）评估训练结果，并且通过将学生的语音数据添加到视觉符号（音调符号）来将评估结果反馈给学生。这一过程使学生直观地捕捉到客观的语音评价，加深了对语音评价的理解.学生主导型：对于传统的LL设备，教师通过切换操作直接连接到学生，并听取和评估学生的发音。这会导致学生因教师的打断或对学生发音的评价而感到焦虑或不满。该系统可以被认为是学生反复训练和理解发音，然后向教师请求评价以消除学习焦虑的系统。3.不受时间和空间限制的学习和纠正教学：将学生意图传输的语音数据一次性存入数据库。教师在课余时间也可以对语音数据进行校正和教学，学生可以随时从数据库中看到评价结果。然后，由学生发送的语音数据和评估结果被合并为一个整体，并呈现给学生，该学生可以记住，而不管时间的流逝，并再现当时的学校情况。
