An AI-driven real-time Swahili Sign Language Recognition system designed to bridge communication gaps between the hearing-impaired community and the general population and outperforming several existing models is proposed.
Abstract
Hearing impairment is a growing global health challenge that disproportionately affects people in resource-constrained countries such as Tanzania, where access to assistive technologies remains limited. Conventional solutions, including hearing aids, cochlear implants, and interpreters, are often costly and inaccessible. This study proposes an AI-driven real-time Swahili Sign Language Recognition system designed to bridge communication gaps between the hearing-impaired community and the general population. The system integrates Convolutional Neural Networks (CNNs), Scale-Invariant Feature Transform (SIFT), and Long Short-Term Memory (LSTM) with computer vision techniques to recognize and interpret sign gestures. SIFT extracts key features from images captured via webcam, while CNN performs classification and LSTM models temporal dependencies for improved accuracy. Experimental results reveals high recognition accuracy of 98.5% and a low error rate of 0.1345%, outperforming several existing models. The system offers an effective, affordable solution for enhancing communication among Swahili-speaking communities.
This proposed research presents a real-time American Sign Language (ASL) recognition system for 24 dynamic signs that integrates the MediaPipe frame work with Long Short-Term Memory (LSTM) network to achieve efficient real-time dynamic sign recognition with reduced computational and data requirements.

SignAura is introduced, an artificial intelligence-driven real-time SLSL sign-recognition system that provides multilingual lexical text and synthesized speech and performs isolated sign-level recognition and provides corresponding multilingual lexical output rather than complete grammatical sign-language translation.

An efficient process for recognizing sign languages plays an important role in reducing the communication barrier between hearing-impaired people and others. Nevertheless, most of the currently available sign language recognition processes fail to produce highly accurate results within a minimum time period. In this pa...
