Targeted Linguistic Analysis of Sign Language Models with Minimal Translation Pairs

Diane Brentari, Greg Shakhnarovich, Kanishka Misra, Karen Livescu, Serpil Karab\"ukl\"u, Shester Gueuwou

Sign language translation models rely primarily on manual hand cues and miss key non-manual cues from the face and body.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our results show that, while the model performs above chance level on most of the phenomena, it relies strongly on manual cues while often missing crucial non-manual cues.

C2weakest assumption

That the minimal translation pairs in ASL-MTP cleanly isolate individual linguistic phenomena without confounding interactions between manual and non-manual channels, and that ablating input cues during training and inference produces a faithful measure of the model's internal reliance rather than an artifact of the ablation procedure.

C3one line summary

A new ASL minimal pairs benchmark shows state-of-the-art sign language translation models perform above chance on many phenomena but rely heavily on manual cues while missing non-manual ones.
