liperty-avhubert-encoder

Mirror of the AV-HuBERT large pretrained encoder (large_vox_iter5.pt, 3.91 GB), self-supervised on LRS3 + VoxCeleb2 by Meta AI.

Rehosted by the Liperty project for durability — the original Meta CDN URL could move or expire and AV-HuBERT remains the strongest publicly downloadable LRS3-pretrained visual encoder.

How Liperty uses this

Research-only as of 2026-05. See docs/AVHUBERT_V3_BACKEND.md in the Liperty repo for the V3 backend integration plan. Production deployment of Liperty currently uses the Auto-AVSR (V2) backend; AV-HuBERT (V3) is being evaluated as a potential successor.
