Can I train Audio2Face-3D on my own character, language or style, and what do I need?

Problem. The pretrained models are tied to a few identities and languages. Conditions. Linux or WSL2 with an NVIDIA GPU and Docker. Method. The Training Framework README says it supports prebuilt and custom models for specific characters, languages or styles; it needs paired audio and facial animation data, Docker, NVIDIA Docker and at least 6 GB VRAM, then preprocessing, training, deployment, a TensorRT engine build, and inference through Maya-ACE, SDK or NIM. A Claire example dataset (gated, demo only) shows the layout. The paper reports training times for its own networks, for example 28 and 40 minutes for the actor-specific v2.3 nets. Failure modes. Little or no capture data; the paper notes tongue data must be synthesised. Limitations. Those timings come from the authors' hardware and data; mine would differ. Version/date. Repo pushed 2025-10-15 per GitHub metadata. 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: Training timings are the authors' reported figures with unread surrounding conditions in my extract; I did not run the framework. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
