Design and Development of an English Listening Website

本项目的目的是设计和开发一个英语听力练习网站。这个项目分为两个部分。第一个是开发用于使用html标签和Java脚本自动标记计算机科学文档的软件。第二部分是开发具有细微差别的相同文档的流媒体速成电影，第一部分是通过对计算机语言的分析和确定基本的通用词汇集来实现的。该集合用作非索引字列表，用于定义不会被标记用于词典查找的单词。最终的标记页面允许一键查找词典，具有许多单词的发音样本。在项目的第二部分，阅读相同的文件并将其录制到录像带上。然后，这盘录像带被数字化，并转换成可以通过流媒体QuickTime访问的“暗示”电影。人们尝试了几种为电影添加字幕的系统。尽管这看起来很简单，但实际上并非如此。最后确定，文件应分为四至五个单词短语，并另存为文本文件。然后，这些文本文件被转换成Quick Time电影，其中每个短语出现大约两秒钟。然后，电影被回放，作为文件视频记录的提示器。因此，语音与文本是同步的，反之亦然。最后，文字电影与语音电影合并，最后的电影被“提示”并放在流媒体服务器上。最后，指向标记文档和流媒体电影的链接被放置在一个网页上，供学生访问。总共有8个文档被标记，并被转换为带有字幕的流媒体电影。

This purpose of this project was to design and develop a website for practicing English listening. There were two parts to this project. The first was to develop software for the automatic markup of computer science documents with html tags and Java Script. The second part was to develop streaming Quick Time movies of the same documents with subtitles.The first part of the project was realized by first doing and analysis of computer language and determining a basic set of common vocabulary. This set was used as a stoplist to define words the would NOT be marked up for dictionary lookup. The final markup pages allow one-click dictionary lookup with sample pronunciation of many words.In the second part of the project the same documents were read and recorded onto video tape. That tape was then digitized and converted to "hinted" movies that can be accessed as streaming QuickTime. Several systems were tried for attaching subtitles to the movies. Although, this appears to be simple, in reality it is not. It was finally determined that the documents should be divided into four to five word phrases and save as text files. The text files were then converted to Quick Time movies in which each phrase appears for about two seconds. The movie was then played back as teleprompter for the video recording of the document. Thus the voice was synchronized with the text and not vice versa. Finally the text movies was merged with the voice movie and the final movie was "hinted" and place on the streaming server.Finally links to both marked-up documents and streaming movies were placed on a webpage for student access. In all eight documents were marked up and turned to streaming movies with subtitles.
