Sign Language Intelligence Ecosystem

USL-AI Suite

We are creating the first fully indigenous Uganda Sign Language (USL) AI ecosystem, a plurimodal architecture designed with, for, and led by the deaf community.

All tools are co-designed with deaf communities, interpreters, educators, and local technologists—ensuring cultural authenticity, linguistic accuracy, and community ownership.

Four Core Components

The Digital USL Dictionary

USL-Lexicon 1.0

A living, evolving computational artifact capturing the richness and complexity of Uganda Sign Language.

Spatial Morphology

Detailed documentation of the spatial structure and formation of signs

Cultural Contexts

Meanings embedded within Ugandan cultural and social frameworks

Regional Variations

Dialectical differences across Uganda's diverse linguistic regions

Semantic Graphs

Linking gestures to indigenous knowledge domains and concepts

Not Just an Archive

This dictionary is not a static archive—it is a knowledge engine powering downstream LLMs, classroom tools, healthcare interpretation systems, and real-time communication interfaces.

Healthcare Sign-Language Dictionary

Diagnostic Interpreter

A specialized module translating between USL and medical terminology, ensuring that deaf patients receive safe, accurate, and respectful care.

Maternal Health

Emergency procedures, prenatal care, and birthing communication

Infectious Diseases

Symptom descriptions, treatment protocols, and prevention education

Pharmacy Communication

Medication instructions, dosage clarity, and adverse reactions

Mental Health

Triage behaviors, counseling support, and therapeutic communication

Grounded in Clinical Workflows

Our healthcare interpreter is not a generic translation tool—it understands medical contexts, clinical urgency, and the specific communication needs of healthcare settings.

Real-Time Bidirectional Translation

USL-Bridge

A hybrid LLM–LVM architecture enabling seamless communication across modalities.

Co-Designed with Community

Deaf Communities

Leading every design decision, from sign selection to interface interactions

Sign Language Interpreters

Ensuring linguistic accuracy and cultural authenticity

Deaf Educators

Shaping pedagogical approaches and learning frameworks

Local Technologists

Building sovereign infrastructure without foreign dependencies

Every line of code, every dataset, every model—created locally, owned by the community, designed for liberation, not extraction.
