## What it is
A JavaScript library for real-time lip-synced talking avatars, rendering full-body 3D characters in the browser. It supports text-to-speech-driven viseme animation, audio-driven lip-sync, and dynamic bone physics for realistic avatar motion.

## Use cases
- add a lip-synced 3D avatar to a chatbot web app
- animate a talking head from text-to-speech output in the browser
- lip-sync an avatar to MP3 audio using speech recognition
- build a virtual assistant with a full-body 3D character
- create an AI avatar for video conferencing with voice lip-sync
- stream low-latency AI speech with a talking avatar over WebRTC

## When to choose
- you need real-time browser-based 3D avatar lip-sync
- you want to pair an LLM/TTS pipeline with an animated talking character
- you need audio-driven lip-sync from recorded speech

## When to avoid
- you need pre-rendered video avatars rather than real-time 3D
- you need a non-web platform like native mobile or desktop
- you want 2D cartoon avatars instead of 3D models

## Facets
- artifact type: library
