How LiveAvatar Works
LiveAvatar streams AI avatars in real time using WebRTC technology for smooth, low-latency video and voice communication.
Developers can connect LiveAvatar to their own Large Language Models (LLMs) — such as ChatGPT or custom-trained systems — so avatars respond intelligently in any context.
Creating a Custom LiveAvatar
To train your own LiveAvatar, submit a continuous 2-minute video with:
Listening (15 seconds)

Listening (15 seconds)
The video must be uncut and follow HeyGen’s quality and consent guidelines. Once approved, your avatar can respond in real time through the LiveAvatar API or SDK.
