Big news from NVIDIA! We're open-sourcing Audio2Face, our AI-powered real-time facial animation model. This cutting-edge tech brings 3D avatars to life — from games to virtual assistants — with stunningly realistic lip-sync and emotional expression.
What Is Audio2Face?
Audio2Face uses generative AI to animate faces in real time from just audio input. Whether you're building a video game NPC or a virtual customer service rep, this tech helps characters speak and emote like real people.
🔊 It analyzes audio features like intonation and phonemes, then turns them into facial animations and expressions — all in real time or offline.
Why It Matters
Until now, creating realistic character animation took tons of time and manual work. Audio2Face changes that — and now that it’s open source, any developer can integrate it into their workflow.
What’s Included?
Here’s what NVIDIA is offering as part of the open source release:
| Package | Use |
|---|---|
| Audio2Face SDK | Everything you need to animate faces from audio — locally or in the cloud |
| Autodesk Maya Plugin (v2.0) | Add AI-driven facial animation to Maya projects |
| Unreal Engine Plugin (v2.5) | Real-time integration for UE5.5 and 5.6 |
| Training Framework (v1.0) | Train and fine-tune your own facial animation models |
Also included: example datasets, pretrained models, and emotional expression tools.
Real-World Adoption
Audio2Face isn’t just theory — it’s powering production pipelines today:
🎮 Reallusion integrated it with iClone and Character Creator to simplify animation workflows.
🧑🚀 Survios used it in Alien: Rogue Incursion Evolved Edition to accelerate lip-syncing and improve immersion.
☢️ The Farm 51 brought it into Chernobylite 2: Exclusion Zone, enabling detailed, emotion-rich animations that weren’t possible before.
More Developer Updates from NVIDIA
