Abstract: Sign language serves as the primary mode of communication for the hearing and speech-impaired community. However, a significant communication gap exists between sign language users and non-signers, necessitating the development of automated translation systems. This paper presents a robust Sign Language Recognition (SLR) system designed to interpret isolated gestures from video sequences. The proposed methodology leverages Google MediaPipe for efficient, lightweight 3D pose extraction, capturing spatial dependencies of hand and body keypoints. These temporal sequences are subsequently processed using Long Short-Term Memory (LSTM) networks to classify gestures. Experimental results utilizing a subset of the WLASL dataset demonstrate that the proposed skeleton-based approach achieves high recognition accuracy while maintaining low computational complexity, making it suitable for deployment in real-time accessibility applications.
