Based On Speech Recognition Technology, Interactive Graphics System Design And Implementation

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.
