# P4 voice panel
Bundles **`voice_assistant/`** firmware plus `.vscode`/`.cursor` configs and **`example.code`**.
Treat this as companion UI work to **`p4 chatbot 83125/`** unless you refactor modules.
Recommended flow:
```bash
cd voice_assistant
```
Follow manifests inside (`CMakeLists.txt`, `sdkconfig.defaults`, Arduino project files, etc.—whichever framework that folder uses). Keep generated `build/` / `.pio/` directories excluded from commits.
