An innovative AI system has been developed to bridge communication gaps for South African Sign Language users.
A University of KwaZulu-Natal graduate, Akhil Hansrajh, created an artificial intelligence system that translates South African Sign Language (SASL) into speech in real time. This groundbreaking technology, part of his final-year project, utilizes computer vision and machine learning to convert signs into spoken language.
AI Breakthrough for South African Sign Language
The SASL-to-Speech Translation System employs a custom AI model that tracks body landmarks to recognize signs. It was trained on a specially developed dataset for SASL, enabling it to identify individual letters and words. The system then converts these into spoken language using a text-to-speech model.
This project stands out as one of the first assistive technology initiatives at UKZN’s Electrical, Electronic and Computer Engineering discipline that focuses on SASL. The recognition of SASL as South Africa’s 12th official language underscores the importance of developing technologies that cater to local communication needs.
Personal Inspiration Behind the Technology
Akhil Hansrajh’s motivation for this project stems from his personal background. His parents were born hard of hearing, and he has witnessed the challenges they face in communication. This experience fueled his desire to create a tool that allows SASL users to communicate more independently with those unfamiliar with the language.
The project supervisor, Sulaiman Patel, highlighted the significance of this initiative in enhancing accessibility for the deaf community in South Africa. The technology not only addresses a local need but also showcases the potential of AI and computer vision in developing tailored solutions.
Future Development Plans
- Akhil Hansrajh plans to enhance the system’s word recognition capabilities.
- He aims to improve the fluency and cohesiveness of the generated speech.
- Hansrajh is pursuing a career in software, networking, or artificial intelligence and machine learning.
This AI innovation represents a significant step towards inclusive communication in South Africa.
