TL;DR
The results suggest that Portuguese-specialized encoder-decoder models are a promising direction for Gloss-to-Text translation in low-resource settings.
Abstract
We evaluate encoder-decoder models for Gloss-to-Text translation from Brazilian Sign Language (Libras) glosses into Portuguese using a corpus derived from Libras-UFPel. The evaluated models are mT5-small, mT5-base, Flan-T5-base, and PTT5-v2-base. Experiments were conducted with 5-fold cross-validation and evaluated using BLEU and chrF. All models improved after supervised fine-tuning, with PTT5-v2-base achieving the best overall performance. The results suggest that Portuguese-specialized encoder-decoder models are a promising direction for Gloss-to-Text translation in low-resource settings.
This work combines vocabulary surgery for tokenizer adaptation without full retraining, cross-lingual transfer of quality classifiers via translation, enabling filtering without target-language annotations, and generation of instruction data through translation, task conversion, and targeted synthesis.

Speech-to-text translation for low-resource language pairs such as Vietnamese–English remains underexplored, despite growing demand in real-world applications. In this study, we present a systematic zero-shot benchmark on the Vietnamese test split of FLEURS, evaluating 30 configurations across three system families: co...

Results from automatic and human evaluations show that fine-tuning on IMPaCTS improves performance both in terms of task completion and adherence to the targeted readability levels compared to few-shot baselines.
