Introduction
Importance of Indian Sign Language (ISL)
Indian Sign Language (ISL) is a vital communication medium for the deaf and hard-of-hearing communities, relying on hand gestures, facial expressions, and body language. However, a lack of public knowledge about ISL leads to social exclusion and limited inclusivity. Innovative solutions using artificial intelligence (AI) and machine learning (ML) aim to bridge this communication gap and promote greater accessibility.
2. Literature Survey Overview
Kumar et al. [1]
Developed a system using image processing and ML to translate sign language into speech.
Techniques like support vector machines (SVMs) and neural networks were employed.
Focused on real-time gesture recognition, but faced challenges with lighting conditions and dataset quality.
Lee et al. [2]
Proposed a real-time sign recognition app that learns from user interaction.
Aimed at bridging the communication gap between signers and non-signers in digital environments.
The system adapts to different signing styles over time but is computationally demanding.
Patel et al. [3]

3. Technological Enhancements and Frameworks
The proposed framework uses deep learning for real-time ISL recognition and translation.
Utilizes the YOLO (You Only Look Once) model for fast and accurate gesture detection.
Supports fluid communication between ISL users and non-signers.
Zhang et al. [6]
Demonstrated how combining CNNs and LSTM (Long Short-Term Memory) improves continuous gesture recognition.
Emphasized spatial and temporal modeling for accurate sign interpretation.
Adapted YOLO for real-time hand gesture detection.

Highlighted the importance of multimodal systems (visual + audio input) for improved accuracy and user experience.
Tajima et al. [8]
Addressed real-world challenges like background noise, style variation, and obstructions in gesture recognition.
Called for robust, synchronized systems integrating gesture detection and speech output for seamless communication.
Conclusion
The paper employs sign language translation technologies, collectively reflecting substantial strides toward fostering communication for people who are deaf or hard of hearing. They all confirm the efficacy of machine learning and computer vision approaches to an accuracy that recognizes various sign language gestures well. Utilizing procedures like convolutional brain organizations (CNN), these frameworks catch the motions as such as well as the nuances of looks and body act, vividly adding to the semantics of communication through signing.
