【摘要】 CAD绘图交互方式的便捷程度对CAD技术的应用普及起着决定的作用。当前，语音识别关键技术的突破使得采用语音方式进行人机交互成为现实。实现一个具有语音交互绘图功能的CAD系统将使CAD的操作向更符合人类自然习惯的方向迈进。 本论文讨论了语音交互CAD系统的总体设计方案，结合语音识别、XML、面向对象、图形处理等技术的应用，着重论述了语音与Windows消息的映射、特定系统语音识别率的提高以及语音交互命令的规范等关键问题的解决方法。此外，论文还介绍了一个语音开发平台的搭建方法，运用此平台可以明显缩短语音交互应用程序的开发周期。 将语音识别技术应用于CAD的研究还刚刚起步，论文的研究内容是在这方面的初步尝试，开发的系统雏形运行结果则表明采用语音进行人机交互绘图的解决方案是可行且实用的。更多还原

【Abstract】 Convenient interactive Computer Aided Design drawing mode plays an important role in the popularization of CAD technology, and the progress in speech recognition technology makes it available to send command to computer via voice. Voice interactive drawing can help users to operate the CAD system with natural human custom.This dissertation gives a whole design scheme of the voice interactive CAD system with an orderly combination of related parts: Speech recognition, XML, Object Oriented Programming and image manipulation. It mainly discusses the solutions of mapping from voice to Windows Message, the way of increasing speech recognition rate and the criterion of voice interactive demand. And it also provides a method of building a platform of voice development. With this platform the interactive voice applications can be fast developed.It is just the start to apply the technology of speech recognition into CAD system research. In this paper, a CAD system combined with the speech recognition technology is developed and the running results demonstrate that the scheme for the man-machine interactive design via voice is feasible and available.更多还原
