HunyuanVideo-Avatar - Tencent hybrid open source voice digital human model

What is HunyuanVideo-Avatar?

HunyuanVideo-Avatar is an advanced voice-activated digital human model jointly launched by Tencent's Hunyuan team and Tencent Music Tianqin Lab. Based on the innovative multimodal diffusion Transformer architecture, the model generates dynamic videos with natural expressions, lip synchronization, and full-body movements based on character images and audio uploaded by users. The model supports single-player scenarios and can accurately drive multi-character interactions, ensuring that each character's lips, expressions and movements are perfectly synchronized with the audio to achieve natural and smooth dialogues and performances.HunyuanVideo-Avatar supports a wide range of styles and species, such as cyberpunk, 2D anime, and Chinese ink paintings, etc., to meet the needs of creativity in different fields.

Main Features of HunyuanVideo-Avatar

• Video Generation: The user uploads an image and audio of a character, and the model automatically analyzes the audio emotion and environment to generate videos of natural expressions, lip synchronization, and full-body movements.
• Multi-Role Interaction: Accurately drive multiple characters in multiplayer interactive scenarios to achieve perfect synchronization of lips, expressions and movements with audio.
• Multi-style support: Supports a variety of styles such as cyberpunk, 2D anime, Chinese ink painting, etc. to meet different creative needs.
