Low-Resource Sign Language

A sign language for which standardised corpora, training data, technical infrastructure, and institutional support are limited compared to 'high-resource' sign languages like American Sign Language (ASL) or German Sign Language (DGS). Low-resource sign languages — such as Bangla Sign Language, Indian Sign Language, and many African sign languages — are often still evolving, exhibit significant regional variation, and rely on linguistic authority held by teachers and community members rather than centralised datasets. AI systems trained on high-resource sign languages frequently fail when applied to low-resource ecologies, reinforcing linguistic hierarchies unless researchers adopt community-guided, teacher-validated, and governance-aware approaches.
