Research of"Voice on Demand" system

记录本是视障人士的重要媒介之一。如果将录音本制作成电子版，通过网络使用，对视障者的学习似乎非常有效。调查：调查了盲文图书馆和公共图书馆的记录本现状。数字记录本标准：对使记录本电子化的各种标准进行了审查，人们已经认识到MP3在这方面是有用的。记录本组成系统：研究了模拟数据数字化的方法。然而，许多低效率的部分仍然存在，因此负责记录的志愿者可以在技术上选择一种简单的方法。网络通知分配实验在这个实验中，它是关于实时相同的时间利用率。特别指出了该高速缓存服务器的重要性。此外，还进行了基于互联网的通知分配实验。现场实验：在现有研究成果的基础上，构建了“语音点播”系统，并进行了现场实验，对实际应用中的问题进行了研究。在这种便携式终端中，虽然接收数据，但由于代码不必要而成为有利媒体的东西对于视障者来说是显而易见的。从结果来看，建议通过使用网络上的数字记录书籍来快速改善视障者的学习环境。

The recording books are one of important media for the visually impaired person. It seems to be very effective for the visually impaired person's study if the recording books made electronic can be used through the network. Then, the system which in real-time used a digital recording books was researched.Survey : The current state of the recording books in the braille library and public library was investigated.Standard of digital recording books : Various standards to make the recording books electronic were examined It has been understood that MP3 is useful in that. Recording books composition system : The method of digitalizing analog data was examined. However, a lot of inefficiency parts remained so that the volunteer who took charge of the recording might technically select a simple method.Network notice assignment experiment In this experiment, it was concerning a real-time same time utilization. Especially, it was pointed out that the cache server was very important. Moreover, the notice assignment experiment using the Internet was done. A lot of suggestions of the data delivery in narrow-band were obtained.Field experiment : "Voice on Demand" system was constructed based on the current research result, And, the field experiment was executed, andthe problem for practical use was investigated.Wireless notice assignment experiment using portable terminal : The browser of the Internet reserved books. In this portable terminal, the thing which was profitable media because of the code unnecessary though data was received for the visually impaired person turned out.From the result, it was suggested by using a digital recording books on the network rapidly improved visually impaired person's learning environment.
