Fay is an open-source Python digital human framework that connects 2.5D/3D/mobile/web digital humans or OpenAI-compatible LLMs to business systems. It provides streaming voice and text interaction interfaces with pluggable ASR, TTS, and LLM models, plus agent tool-calling and MCP support.
Use cases
- build a virtual assistant with voice interaction
- create a digital human live streamer or virtual teacher
- connect an LLM chatbot to my business system
- run an offline voice assistant on a local server
- add speech recognition and TTS to a digital avatar
- build a multi-user concurrent voice agent with custom knowledge base
- integrate a digital human into a website or mobile app
- configure voice commands that trigger actions
When to choose
- you need a full-stack digital human pipeline with ASR, TTS, LLM, and avatar driving
- you want offline-capable voice assistants with wake word and interruption support
- you need to serve multiple concurrent users from one assistant backend
- you want agent tool calling and MCP integration in a digital human
- you need auto-broadcast mode for virtual anchors or news presenters
When to avoid
- you only need a simple text chatbot without voice or avatars
- you want a lightweight library to embed rather than a full framework service
- you need a permissively licensed project for closed-source commercial use (GPL-3.0)
- you require production-grade enterprise support and SLAs
