[R] EMO: Emote Portrait Alive - Generating Expressive Portrait Videos with Audio2Video Diffusion Model under Weak Conditions

Researchers have struggled to make AI-generated talking head videos that capture the nuance of human facial expressions and speech. Methods usually fail to replicate the fluidity and synchronization of real human mouths and faces.

A new paper from Alibaba proposes **EMO**, an AI system that achieves unprecedented realism in synthesized talking head videos using a novel diffusion model approach.

EMO generates videos directly from audio clips and portrait images, without 3D graphics or animation:

* **Audio encoder** analyzes tone, rhythm …
