Audio2Face 2023.1 Release Highlights#

Audio2Face 2023.1 comes packed with lots of new features, functionality and workflow tutorials. We’ve expanded on our AI models, further improving A2F multi-language support. In addition to our existing Mark AI model, we’ve added a new Chinese female AI model called Claire - providing users with more options for generating realistic facial animations.

2023.1 also includes Livelink and Avatar Streaming, providing the ability to stream blendshape animation from Audio2Face to Unreal Engine, allowing you to drive a MetaHuman character’s facial animation. Blendshapes are supported for tongues on both Both Mark and Claire AI models.

The Streaming audio player now engages Audio2Emotion, providing developers and users the full performance capabilities of Audio2Face. In addition, we have improved the Rest API with more comprehensive controls and the ability to export “emotion keyframes” from Audio2Emotion for use in other applications.
