摘要： 以“Z+Z 智能教育平台的语音识别接口”的研究开发为背景，针对领域构架包含的构件太多和理解使用太复杂的问题，提出了子领域通用构件（General Component for Sub-domain，GCSD）的概念。GCSD 的使用，能极大地简化基于构件的应用程序开发，提高软件生产效率和产品质量；结合基于构件/构架的软件复用技术和领域工程方法，提出了GCSD 的开发方法，并以语音命令识别通用组件的开发为例，展示其开发过程。

Abstract: In the process of research and development of speech recognization interface for Z+Z intelligence education platform, there are too many component interfaces and their usage is too difficult. This paper proposes a concept named GCSD (General Component for Sub-domain), in order to greatly simplify the component based ondevelopment of application software, and improve the efficiency of developing software and its quality, a development method for GCSD is designed referring to the software re-usage and domain engineering, and its development process is demonstrated through the developing of GCSD for recognizing of speech command

Key words: Component; Sub-domain; Domain engineering; Recognizing of speech command
