Product Advantages

Lifelike Digital Human Avatars

Based on ZEGOCLOUD's self-developed Digital Human avatar generation engine, developers can implement two types of avatar customization services: Image Digital Human and Real-person Digital Human.

Image Digital Human (Recommended): With just a single image, AI training can bring the image to "life". Supports various avatar types including real people, cartoons, and virtual characters. The generated avatar has clear speech, natural expressions, and certain natural movements, making it lively and vivid.
Real-person Digital Human: Capture a real-person video and generate a Digital Human with expressions, movements, and facial expressions that rival real people through AI training. Supports custom backgrounds, up to 2K ultra-HD quality, and custom action drive. The Digital Human avatar is realistic with natural effects.

Integrated with Real-Time Interactive AI Agent, Out-of-the-Box Full Pipeline

For interactive scenarios such as AI interactive chat and real-time broadcasting with Digital Human, ZEGO recommends using the real-time interactive AI Agent solution: it relies on the Agent to complete the full ASR, LLM inference, TTS, and Digital Human driving pipeline in one stop, without requiring the business side to connect multiple AI components.
It offers lower interaction latency, more natural Digital Human lip-sync and facial expressions, continuous product feature iteration and upgrades, and more flexible voice configuration.
Ultimate cost-effectiveness: ultra-low pricing, supports high concurrency, meeting scenarios with high usage volumes such as interactive conversations and interactive teaching, helping businesses achieve extreme cost reduction.
