本文介绍了智能技术与系统国家重点实验室开发的“北极光”盲人用计算机软件系统中涉及的语音和语言处理技术。该系统能够获取和分析需要反馈的屏幕信息,通过语音合成平台将其内容朗读出来,对用户进行语音提示;与汉语自动分词、语言模型等自然语言处理技术的结合,使系统能够进行汉字和盲文的转换,反馈信息可以通过盲文点显器输出,使用户能够摸读盲文点字来获取所需要的信息,用户也可以采用盲文输入法进行输入,输入结果可转换为汉字文本形式。
Abstract
Some speech and language processing technique used in the“Aurora”software systemfor the blinds developed by the State Key Laboratory of Intelligent Technology and Systems is introduced in this paper. The software system can obtain and analyze screen information that requires feedback , and read it in virtue of a speech synthesis platform to give information to the users. By using some natural language processing technique , including Chinese word segmentation and language model , the system can realize the transformation from Characters to Braille , and export the information to the Braille display service. Users can obtain the information they need by touching the Braille display device. On the other hand , users can input Braille by using the Braille input tool , and the input result can be transferred to Characters text.
