Nexa: Communication Without Barriers
Nexa is an inclusive communication and assistive technology platform that enables direct, dignified interaction between Deaf, Hard-of-Hearing, and neurodiverse users and the services they depend on.
Powered by AI and designed for South African Sign Language, Nexa eliminates the need for interpreters and third-party dependency — giving users full autonomy over their communication.
How It Works
Four Simple Steps to Dignified Communication
The User Signs
The Deaf, Hard-of-Hearing, or mute user communicates using South African Sign Language through the Nexa interface.
AI Translates
Nexa's AI engine recognizes the signs and converts them into clear, readable text displayed on screen in real time.
Provider Responds
The service provider reads the translated text and responds — either by typing, speaking, or using the FM system.
Communication Bridge
A complete, dignified, two-way conversation happens without interpreters, third parties, or loss of autonomy.
Core Features
Built for Real-World Accessibility
Every feature in Nexa was designed to solve real problems faced by real people in South African service environments.
AI Sign-to-Text Translation
Our AI engine is trained to recognise South African Sign Language (SASL) and convert it into readable text in real time. This enables direct, independent communication between Deaf users and service providers without relying on interpreters.
FM Assisted Communication
An integrated FM-based system designed for noisy or complex environments like hospitals and banks. It ensures clear, direct audio-assisted communication where traditional methods fail.
Sign Language Learning Tools
Built-in SASL reference modules and learning tools empower service providers and individuals to learn basic sign language, fostering understanding and reducing communication friction.
Accessibility-First UI/UX
Every pixel of Nexa is designed with accessibility at its core — high contrast, large touch targets, clear typography, and intuitive navigation that works for users of all abilities.
Offline-Friendly Design
Recognizing South Africa's connectivity challenges, Nexa includes offline-friendly considerations so core features remain accessible even in low-bandwidth environments.
Use Cases
Nexa in Action Across Sectors
Banking & Financial Services
A Deaf customer walks into a bank and uses Nexa to communicate directly with the teller. Sign language is translated to text instantly — no interpreter needed, no privacy compromised.
Healthcare Facilities
A Hard-of-Hearing patient describes symptoms to a doctor using Nexa. Accurate translation ensures correct diagnosis and treatment, potentially saving lives.
Educational Institutions
A neurodiverse student uses Nexa to participate in classroom discussions, access learning materials, and communicate with teachers on their own terms.
Public Transport & Services
Navigating public transport becomes accessible when Nexa helps users communicate routes, schedules, and needs to service operators in real time.
Beta Testing
Tested With Real Users. Refined by Real Feedback.
Nexa has completed beta testing with over 200 participants including members of the Deaf community, the general public, and institutional service providers.
Users reported significantly increased confidence in independent service interactions
Sign-to-Text accuracy improved through iterative feedback loops with SASL users
UX/UI redesigned based on real feedback to improve contrast, readability, and navigation
AI response lag identified and mitigated through performance optimization work
Engagement with AI experts through Twine accelerated technical development
