In this session recorded at Unreal Fest Orlando 2025, Epic Games presents xADA, a model for generating expressive and realistic animation of the face, tongue, and head directly from speech audio.
The approach leverages state-of-the-art machine learning models to extract rich features from audio input to automatically create face and body animation directly on a MetaHuman or MetaHuman-compatible model.
xADA supports two modes of operation: a fully automatic mode and a customizable mode where artists can specify and override emotion and/or blink timings.
This session includes a live demo of xADA. Topics include how the technology behind audio-driven animation works, and how to use xADA in Unreal Engine for offline and streaming character speech animation.
