Alibaba’s Emo AI is revolutionizing digital animation with its ability to generate expressive portrait videos under weak conditions. This new tool sets a new standard for turning images into videos, infusing still images with voice and motion. Emo AI can create vocal avatar videos with various facial expressions and head poses, supporting songs in multiple languages.
Emo AI: Audio 2 Video Diffusion Model
The Emo AI Audio 2 Video Diffusion Model by Alibaba is a groundbreaking tool that can transform still images into expressive portrait videos under weak conditions. Here’s a closer look at how this model works:
Key Features:
- Generates vocal avatar videos with various facial expressions and head poses
- Supports songs in multiple languages
- Intuitively recognizes tonal variations in audio
