Audio2Face converts live speech into synchronized facial animation and allows authors to specify emotional states (e.g., anger, sadness, excitement). Demonstrated by Two Minute Papers (Dr. Károly Zsolnai-Fehér) on 2022-03-12, the system traces to a ~2017 paper, supports face swapping (including nonhuman targets), integrates with Unreal MetaHuman, and is low-cost enough to run multiple instances.
