## Overview

Jarvis is a voice-command assistant. Its runtime listens for speech, recognizes the “Jarvis” wake word, captures a command, dispatches it to a built-in action or AI fallback, and speaks responses. The main script contains both the interaction loop and command implementations; the graph separates these responsibilities while retaining their shared source path. README-described custom music-library support is represented, but the sampled runtime has that integration commented out and instead searches YouTube. The standalone `client.py` demo is not part of the documented runtime flow.

Main entry points: [`main.py`](https://github.com/meeranhusain/jarvis-voice-activated-virtual-assistant/blob/main/main.py) (Command dispatcher), [`musicLibrary.py`](https://github.com/meeranhusain/jarvis-voice-activated-virtual-assistant/blob/main/musicLibrary.py) (Music library)
