NVIDIA Omniverse Audio2Face


Omniverse Audio2Face

Instantly create expressive facial animation from just an audio source using generative AI.

Audio-to-Animation Made Easy With Generative AI

Omniverse Audio2Face beta is a reference application that simplifies animation of a 3D character to match any voice-over track, whether you’re animating characters for a game, film, real-time digital assistants, or just for fun. You can use the app for interactive real-time applications or as a traditional facial animation authoring tool. Run the results live or bake them out, it’s up to you.

How It Works

Audio2Face is preloaded with “Digital Mark”— a 3D character model that can be animated with your audio track, so getting started is simple—just select your audio and upload. The audio input is then fed into a pre-trained Deep Neural Network and the output drives the 3D vertices of your character mesh to create the facial animation in real-time. You also have the option to edit various post-processing parameters to edit the performance of your character. The results you see on this page are mostly raw outputs from Audio2Face with little to no post-processing parameters edited.

Audio2Face generates facial animation through audio input.

Audio Input

Use a Recording, or Animate Live

Simply record a voice audio track, input into the app, and see your 3D face come alive. You can even generate facial animations live using a microphone.

Audio2Face will be able to process any language easily. And we’re continually updating with more and more languages.  

Character Transfer

Face-Swap in an Instant

Audio2Face lets you retarget to any 3D human or human-esque face, whether realistic or stylized. This makes swapping characters on the fly—whether human or animal—take just a few clicks.

Scale Output

Express Yourself—or Everyone at Once

It’s easy to run multiple instances of Audio2Face with as many characters in a scene as you like - all animated from the same, or different audio tracks. Breathe life and sound into dialogue between a duo, a sing-off between a trio, an in-sync quartet, and beyond. Plus, you can dial up or down the level of facial expression on each face and batch output multiple animation files from multiple audio sources.

Emotion Control

Bring the Drama

Audio2Face gives you the ability to choose and animate your character’s emotions in the wink of an eye. The AI network automatically manipulates the face, eyes, mouth, tongue, and head motion to match your selected emotional range and customized level of intensity, or, automatically infers emotion directly from the audio clip.

Data Conversion

Connect and Convert

The latest update to Omniverse Audio2Face now enables blendshape conversion and also blendweight export options. Plus, the app now supports export-import with Blendshapes for Blender and Epic Games Unreal Engine to generate motion for characters using their respective Omniverse Connectors.

Misty the Animated Chatbot

Presented at GTC Spring 2020, Misty is an interactive weather bot that is driven by Audio2Face in run-time. We demonstrated retargeting from a realistic human mesh to a stylized character mesh to be used as an interactive service agent.

Omniverse Machinima

Unveiled during the GeForce 30 series launch, Audio2Face is seen in the Omniverse Machinima demo. Facial animation is notoriously complex and cost-prohibitive. Audio2Face automates detailed facial animation to democratize the 3D content creation process.   

NVIDIA Omniverse is helping me achieve more natural results for my digital humans and speeding up my workflow so that I can spend more time on the creative process.
