JoelShine/JARVIS-AI-ASSISTANT ? reverse-engineered prompt

Build me a Python voice assistant like JARVIS that works offline and can chat, listen to me through the microphone, and speak back with natural sounding text to speech.

I want it to use the ALICE style AIML brain for conversation, with offline speech recognition through Vosk and offline speech output through pyttsx3. It should start from one main script, load the chatbot files, and be easy to run after installing the dependencies and adding a Vosk model. If anything is missing, make the setup straightforward and clear in the code or README so I can get it running on Windows without a lot of manual fixing.

Please make sure it can handle simple spoken commands, open programs, and switch between chat mode and command mode smoothly. If you need to, look up current docs online for any tricky library setup.
