The development of CAI system for language education, making use of voice response and communication function

语言教育的正确目标是掌握顺利进行双向信息传递(交流)的技能。为此，语言实验室已开展了听、说训练，使用录音带等。在一系列研究中，作者一直将英语语言教育作为具体的对象，认为听和说对于语音的实际使用是有效的，特别是在英语语言的四大功能(听、说、读、写)中。对于听力教材来说，语音再现功能是必要的，预先转换为数字语音，偶尔打电话，以及开发说、录音和再现功能的教材，能够记录学习者的发音并在复制后听到自己的发音变得必要。此外，在语音教学方面，需要有辅助功能，能够再现学习者的发音，并将发音错误反馈给学习者。本研究的目的是开发具有上述功能的语言教育计算机辅助教学系统。可以说，特别是教师评价结果的可视化反馈，即通过反复记录和再现会话语体句子，并将最佳结果发送到教师终端，即以指导和纠正的形式，是未来一种新型的语言教育系统。这个系统就是为了解决这些问题而开发的。

The proper aim of language education is the acquirement of skill in carrying out two-way information transfer (communication) smoothly. For this purpose, so far listening and speaking trainings have been carried out, using cassette tape, etc. in LL (language laboratory) .The writers, in a series of their researches until now, have been taking up English language education as concrete objects, considering that listening and speaking are effective for practical use of voice, especially among four functions of English language (listening, speaking, reading, and writing) .For the teaching materials for listening, voice reproduction function to reproduce voice deta, converted to digital in advance, in occasion calls, is necessary, and for the development of teaching materials for speaking, recording and reproduction function, capable of recording learners' pronunciation and listening their own pronunciation after reproduction, becomes necessary. Further, from the aspect of phonetic instruction, support function, capable of reproducing learners' pronunciation by their teacher and feeding back the error in their pronunciation to learners, is necessary.The aim of this research is the development of CAI system for language education with the above mentioned functions. It can be said that especially, feeding back of the result of teacher's evaluation in visual from, that is, in the form of instruction with correction, by repeated recording and reproduction of conversational style sentence and sending optimum result to teacher's terminal, as this system, is a new style of language educational system in the future. This system was to be developed for solving these problems.
