Target-Side Paraphrase Augmentation for Sign Language Translation with Large Language Models
Researchers demonstrate that GPT-4o-generated paraphrases can improve sign language translation by augmenting training data while keeping video inputs unchanged. Testing across three sign language datasets reveals modest gains on PHOENIX14T (9.56 to 10.33 BLEU-4) but exposes fundamental limitations when data is sparse or highly controlled.
