AI digital humans are no longer sci-fi—they’re transforming how we stream, engage, and scale content delivery in real time. From 24/7 live shopping hosts to interactive co-hosts in social rooms, these intelligent avatars are creating entirely new experiences across industries.
In this post, we’ll explore how you, as a developer, can build your own AI-powered digital human for live streaming using ZEGOCLOUD. Whether you’re working on a social app, an e-commerce platform, or a virtual classroom, this guide will help you get started.
What Is an AI Digital Human?
An AI digital human is a virtual character that interacts with users in real time using lifelike speech, facial animation, and conversation—powered by large language models (LLMs), voice cloning, and avatar rendering.
Typical stack includes:
- Conversational AI (e.g. GPT, MiniMax, Doubao)
- TTS + Voice cloning
- Lip-sync avatar rendering
- Real-time audio/video streaming
Real-World Use Case of AI digital humans
In a recent campaign, a Baidu livestream used two AI digital humans—one modeled after a real influencer. In just 26 minutes, the AI host outperformed the real one’s 1-hour show. Revenue hit $7.65 million, with over 13 million views.
YY Live’s digital human “Ling’er” helped increase daily user interactions by 670%, cut down operational costs, and boosted paying users by 80%+.
