The Performance Comparison between Speech Recognition Tool and Text Interpreting when Class Archives are made with Subtitle for Communication Access

我们可以从配合我们研究的聋生那里得到报告。它是系统错误识别和错误转换的数据，通过重复输入到语音识别引擎中。此外，在Gumma大学金泽实验室的支持下，我们进行了文本翻译的替代打字方法与重复类型语音识别方法的并行试验。对于文本翻译和语音识别，我们了解到，随着美国的调查，它们作为业务逐渐分离。每个客户群体都在划分。现在，在日本，语音到文本服务并没有实现为商业服务。然而，这是肯定要考虑的主题，当我们在高等教育中实现连续的语音到文本服务时，我们的研究在科研资助下得到了以下结果：(1)可以在捕获系统中设置语音识别引擎(自然地说是Dragon)作为视频同步字幕。(2)由两个或多个人交替打字操作的文本翻译系统(IPTalk)是目前最有用的，当我们比较一些语音到文本系统的实际使用程度时。(3)当我们比较文本口译字幕人员和重复/纠正人员的两种培训时，前者是有利的。这是因为文字翻译设备简单，也不需要专门的房间。然而，在美国，语音识别系统的操作员的劳动力成本高于文本翻译。这是因为很多人认为语音识别系统的操作是一项“艰巨的工作”。

We could get the reports from the deaf student who cooperated in our research. It is the data about incorrect recognition and incorrect conversion by the system which inputs into the voice recognition engine by repetition. Moreover, supported by Kanazawa laboratory in Gumma University, the alternative typing method for Text interpreting was experimented in parallel with the method of repetition type speech recognition.As for Text interpreting and speech recognition, we appreciated that they were separated gradually as business, by investigation in the U.S.A. Each customer group is being divided. Now, in Japan, Speech-to-Text service is not materialized as business. However, this is the subject which must surely be considered, when realizing continuous Speech-to-Text service in higher education.We were able to get the following results in our research supported with the grants-in-aid for scientific research.(1) It became possible to set a speech recognition engine (Dragon Naturally Speaking) into the capturing system as a video-synchronous subtitle.(2) Text interpreting system (IPTalk) operated by two or more person's alternative typing is most useful at present when we compare degree of practical use in some Speech-to-Text Systems.(3) When we compare two trainings for captionists of Text interpreting and for repetition/correction person, the former one is advantageous. It is because Text interpreting is simple for equipment and the special room is not needed, either. However, the operator of a speech recognition system has a labor cost higher than Text interpreting in the U.S. which precedes. This is because many people think that operation of speech recognition system is "difficult work."
