Research And Implementation Of Drawing Command Set Generator In Voice Aided Drawing System

With the globalization of trade and the introduction of the concept of Industry4.0,China has entered the era of intelligent manufacturing.In this context,doing a good job in computer-aided drawing is of great significance for the development of the manufacturing industry.In traditional drawing work,users usually interact with the computer through keyboard and mouse,resulting in heavy repetitive workload and low drawing efficiency.By introducing speech recognition technology,converting voice commands issued by users into text commands,and using a voice assisted drawing system to draw,it is possible to achieve voice command control over computer graphics,thereby solving the above problems.Therefore,based on this research direction,developing a drawing command set generator suitable for voice assisted systems is conducive to achieving efficient and intelligent computer-aided drawing.This article first performs an overall analysis of the drawing command set generator,including functional requirement analysis,logical architecture design,and system architecture design.Secondly,the recognition function of the generator is implemented.Learning the overall framework and recognition process of speech recognition,analyzing the speech recognition task,and implementing online speech recognition function using the Baidu Speech Recognition API and the Qt development environment,with a recognition accuracy of 93.2%.Once again,the command set generation function is implemented.Building a language model by introducing concepts such as word units,synonyms,and phrase models,two different drawing command set generation methods are proposed for different application scenarios: one is a speech interaction generation method,and the other is a speech batch processing generation method.Finally,the drawing command set generator is designed and implemented.The selected second-level development method is chosen,and the system database is designed.A AutoCAD second-level development environment is built,and the drawing command set is used to drive AutoCAD for automatic drawing.After testing,the function of the drawing command set generator meets the expected requirements,and it can be applied to a speech assist drawing system to help it recognize users’ speech commands.
