SignThought: A New Gloss‑Free Sign Language Translation Framework for the Deaf Community

The paper introduces SignThought, a gloss‑free sign language translation model that inserts an ordered latent‑thought chain between video encoding and text generation, uses a plan‑then‑ground decoding strategy, and is evaluated on five benchmarks and a newly built 1,311‑hour LC‑HKSLT dataset, achieving state‑of‑the‑art BLEU‑4 and ROUGE scores.
