## What it is
OpenAvatarChat is a modular interactive digital human (talking avatar) chat application that combines ASR, LLM, TTS, and avatar rendering components into a low-latency real-time conversation system. It supports multiple avatar technologies (LiteAvatar, LAM, MuseTalk, FlashHead) with swappable components and ~2.2 second average response time.

## Use cases
- build a real-time talking avatar chatbot
- run a digital human assistant that listens and speaks
- swap ASR, LLM, TTS, and avatar components in a voice chat pipeline
- create an interactive virtual presenter with lip-synced video
- demo a multimodal conversational AI with voice and video input
- self-host a low-latency voice-to-avatar conversation service

## When to choose
- you need a full-stack digital human chat demo or product with swappable components
- you want real-time voice conversation with a lip-synced avatar
- you want to experiment with different avatar rendering technologies in one framework

## When to avoid
- you only need a text-only chatbot without avatars or speech
- you lack a GPU or cannot host models locally
- you need a production-grade managed service rather than a self-hosted research framework
