Research and application of speech assisted modeling technology based on .NET framework

Three-dimensional geometric modeling of parts includes wireframe modeling, surface modeling, and solid modeling, which are generally generated by CAD software. This paper proposes a new speech modeling technique, which is mainly a secondary development of AutoCAD using C# language under .NET framework. The development includes three parts: speech recognition, data mapping processing and parametric modeling, and takes the floating head heat exchanger as the research object, and realizes the speech modeling of some of its parts.
