Development of Telephone-Communication System and Program for Hearing-impaired Children

检查了听障人士电话、辅助电话设备和正常电话的功能。作为这项研究的结果，我们发现了两件事。只有一种电话可以放大到足以让听力受损的人通过电话进行交流。普通电话的一些功能对他们的交流也是有用的。作为我们去年开发的电话系统实际使用的结果，澄清了三点。(1)电话系统的电声特性对听障人士的使用并不总是很好。(2)电话与辅助设备耦合系统的电声特性并不总是稳定的。(3)电话系统的使用方式(电话/电话和辅助设备)必须根据听力水平的不同而灵活。制定了听障儿童电话通信培训方案。该计划分为三个步骤。第一步是提出通过最好的电话系统进行沟通的意愿。第二步是利用有明确目的的电话。第三步是享受电话交谈的乐趣。每一步都对受检儿童的情况和指导过程进行了分析。作为分析的结果，指出了以下几点。对于第一步，首先介绍了在电话交谈中出现的常见词汇。对于第二步，当沟通中断时，必须教授一些克服糟糕情况的策略。对于最后一步，语言教学和听觉学习是他们成功进行电话交流的关键。我们还调查了听障成年人对电话交流的意见。通过这个项目的所有发现，我们讨论了未来为听障人士提供电话通信的可能性。

Telephones for the hearing-impaired, assisting telephone devices and functions of normal telephones were examined. As the results of the study, we found two things.There was only one telephone that amplifies enough to communicate for the hearing- impaired through telephones. Some functions of normal telephones were also useful for them to communicate.As the results of real usage of the telephone system which we developed last year, three things were clarified. (1)Electronic acoustic characteristics of telephone system was not always good for the hearing-impaired to use. (2)Electronic acoustic characteristics of coupling system between telephones and assisting devices was not always stable. (3)The way of telephone system use (telephone/telephone and assisting device) must be flexible in accordance with the degree of hearing level.The training program of telephone communication for hearing-impaired children was developed. There were three steps for the program. The first step was to bring up the will to communicate through the best telephone system. The second step is to utilize telephones with definite purposes. And the third step is to enjoy them in telephone conversation. For each step, the situation of children we examined and the processes of the guidance were analyzed. As the results of the analysis, following things were pointed out. For the first step, common words which occurred in the conversation over a telephone were introduced at first. For the second step, when discommunication happens, some strategies which over come the bad situation must be taught. And for the final step, language teaching and auditory learning are the key points for them to success further telephone communication.We also examined the opinions of hearing-impaired adults on telephone communication. Through all findings of this project, we discuss the future possibility of telephone communication for the hearing-impaired.
