Voice Draft Assist allows AutoCAD users to issue commands verbally using natural speech. This multi-threaded system integrates the Whisper LLM for real-time transcription and passes the recognized text directly to the AutoCAD command line. The result is a hands-free drafting workflow that greatly enhances speed, comfort, and overall efficiency.
About This Project
Voice Draft Assist was designed to reimagine how engineers interact with AutoCAD. By combining AutoLISP with external AI components, the system provides a seamless interface between human speech and AutoCAD’s command processing. Users can focus their attention on design — not typing commands or navigating menus.
- Voice-Controlled Command Input: Executes AutoCAD commands through spoken keywords or phrases.
- Multi-Threaded Processing: Runs the speech recognition engine independently, ensuring AutoCAD remains responsive.
- Whisper LLM Integration: Leverages AI for highly accurate speech-to-text transcription across accents and environments.
- Custom Command Mapping: Users can easily configure which spoken phrases correspond to AutoCAD commands, stock or custom.
- Ergonomic Efficiency: Keeps the user’s hand on the mouse and eyes on the screen, reducing fatigue and improving focus.
This program showcases how emerging AI models like Whisper can be combined with traditional CAD automation tools to create intuitive, next-generation drafting experiences. It’s a major step toward hands-free design in professional CAD environments.
Voice Draft Assist demonstrates the possibilities when AutoLISP is extended with AI-driven tools, bridging human speech and geometric creation in AutoCAD.
