Research Of Speech Assisted Geometric Modeling System

In the dissertation,the speech-assisted geometric modeling system is designed by applying the recognition technology to the geometric modeling system.The system uses human-computer interaction combining the input device and voice command and allows users to interperse voice-assisted command geometric in modeling process.In this way,computer can quickly understand the user's intention to improve the efficiency of geometric modeling.The system is developed with Solid Works as the development platform,C++ as the development language and Microsoft Speech SDK as the voice development toolkit,and adopt the speech recognition technology,Extensible Markup Language,component object model technology and object-oriented Modeling and programming technology to achieve.According to the demand information,the overall scheme of the system is designed and the modularization is carried out.The system is divided into three modules: vocabulary library establishment module,command recognition module and driving modeling module.The modules are interconnected through Solid Works platform.Summarize the voice commands that are suitable for assisting the modeling,and use the XML technology to build the voice support command vocabulary.With the help of Microsoft Speech SDK and component object model technology,the real-time recognition of voice commands is done and the recognition results are regularized,and the corresponding message processing is made according to the type of voice commands.The application of speech recognition technology in geometric modeling software is only at the stage of preliminary exploration.Summarizing the phonetic commands can help to complete the geometric modeling and improve the modeling efficiency to a certain extent.The result of the system test shows that the system.The overall design is reasonable and feasible.
