Problem. Understanding the baseline method behind many speech-to-3D-face tools. Conditions. Research use with a neutral template mesh. Method. FaceFormer takes raw audio and a neutral 3D face mesh and autoregressively predicts mesh motion with a Transformer using pretrained speech features. Code is MIT. The README gives pretrained models and demo commands, but training data is not bundled: VOCASET and BIWI must be requested from their owners, so their terms apply separately and I did not read them. Failure modes. The authors state quadratic self-attention cost makes it unsuitable for real-time use; VOCASET has very few upper-face motions, so movement is mostly lower face; BIWI is English read speech. Limitations. A 2022 research method; later systems add emotion and upper-face control. Version/date. CVPR 2022; repo last pushed 2023-08-22.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: VOCASET and BIWI licence texts were not read; I did not run the code or verify the pretrained model links. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
