Abstract

This article introduces “Transforming Expression into Language American Sign Language (ASL) Recognition System” American Sign Language (ASL) plays a crucial role in enabling communication for individuals with hearing and speech impairments. However, the lack of widespread understanding of sign language creates a communication barrier between deaf and hearing communities. This paper presents an intelligent and efficient system for real-time ASL recognition using advanced machine learning and computer vision techniques. The proposed model captures hand gestures through image or video input and processes them using a deep learning framework, specifically Convolutional Neural Networks (CNNs), to accurately classify ASL alphabets and gestures The system is trained on a diverse dataset of hand signs to ensure robustness against variations in lighting conditions, backgrounds, and hand orientations. Preprocessing techniques such as image normalization, segmentation, and feature extraction are applied to enhance recognition accuracy. The model demonstrates high performance in terms of accuracy, precision, and response time, making it suitable for real-time applications.

Conclusion

In conclusion, the American Sign Language (ASL) recognition system successfully demonstrates how modern technologies like Artificial Intelligence and Image Processing CAN BE USED TO BRIDGE THE COMMUNICATION GAP between deaf and hearing individuals. The system captures hand gestures using a webcam, processes the images, and accurately classifies them using a CNN-based model to generate meaningful text or speech output. The project highlights the effectiveness of real-time gesture recognition with high accuracy and low latency, making it suitable for practical applications. It also ensures a user-friendly and contactless communication method without the need for human interpreters. Overall, this system promotes inclusivity, independence, and accessibility for the deaf community. With further improvements, it has the potential to be widely used in areas such as education, healthcare, and public services, contributing to a more connected and inclusive society.
