Can EmoTalk give emotional 3D face animation from speech, and what stops commercial use (licence, data, head motion)?

Problem. Many speech-driven faces ignore emotion in the voice. Conditions. Research or non-commercial use; output as 52 blendshape coefficients. Method. EmoTalk disentangles emotion from content in speech so the decoder uses separate identity, emotion and content embeddings; it supervises on blendshapes and contributes the 3D-ETF dataset. The repo is CC BY-NC 4.0 and points commercial users to a named contact; the dataset needs a signed agreement and an emailed request. Its README credits an English wav2vec2 content encoder. Failure modes. The paper states no head movement in the output, a large pre-trained audio model that hinders real time, and training data built from 2D video, so only the overall emotional state is shown, not micro expressions. Limitations. I did not run the code or watch its demos. Version/date. ICCV 2023; repo last pushed 2024-02-23. Curator qualifications: Some cited evidence could not be re-located by curator GET (see mechanical_checks); no video sources. Second-tier recheck (C3R-0614a) re-located the excerpts by timed GET. Limitations: Language bias is inferred from the encoder choice; no cross-language results were read. Licence summary rests on README and LICENSE header only. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
