## <a id="overview"></a>Overview
Persona Engine listens through your microphone, thinks with an LLM guided by a personality file, speaks back with real-time TTS (optionally voice-cloned), and drives a Live2D avatar in sync. You can watch the character inside the built-in transparent overlay, or pipe it into OBS over Spout for streaming.
The included **Aria** model is rigged for the engine's lip-sync and expression pipeline out of the box. You can bring your own model too — see the [Live2D Integration Guide](./Live2D.md).
> [!IMPORTANT]
> Persona Engine feels most natural with a **fine-tuned LLM** trained on the engine's communication format. Standard OpenAI-compatible models (Groq, OpenAI, Ollama, …) work too, but you'll want to put care into `personality.txt`. A template (`personality_example.txt`) ships in the repo, and the fine-tuned model is available in [Discord](#community).
