A Dual-Mode Sign Language Recognition System for Education and Communication Using CNN and CNN-LSTM Architectures
Year: 2025
Type: article
Abstract: : The Diversified Sign Language Recognition System is designed to enhance educational accessibility for differently-abled individuals by providing an interactive platform to learn and practice sign language. Built using Human-Computer Interaction (HCI) principles, the system features a user-friendly interface with two main modes: Learning Mode and Understanding Mode. The Learning Mode uses a pre-trained CNN model on image-based datasets to help users learn static hand signs for alphabets in an engaging way. The Understanding Mode enables real-time recognition of dynamic gestures using a combination of CNN and LSTM models trained on extracted hand keypoints. It provides immediate text and voice feedback, helping users improve communication skills through an intuitive experience. This system not only promotes inclusivity in education but also empowers differently-abled learners with a supportive tool for mastering sign language more effectively.
