We believe that this balanced and targeted function extraction is key to reaching the high accuracy and generalization efficiency demonstrated by our model. Sign language has long been the cornerstone of communication for the hearing-impaired population, extending beyond their communities to interactions with the hearing inhabitants. As an expressive and autonomous form of communication, signal language plays a significant role in conveying feelings, intentions, and ideas by way of hand movements1. These movements—such as hand trajectory and finger direction—form a wealthy non-verbal language capable of expressing complicated emotional states, judgments, and behavioral awareness.

Our results show that the proposed mannequin successfully addresses frequent points in sign language recognition, significantly confusion between similar handshapes and refined differences in hand positioning. Letters corresponding to ‘M’, ‘Q’, ‘R’, ‘W’, and ‘Y’ are sometimes difficult because of their visual similarities, with minor variations in finger placement and orientation. Nonetheless, our model, which includes multimodal recognition (integrating facial expressions, hand orientation, and body movement), considerably reduces these misclassifications.

5 additional illustrate that the mannequin converges properly over 60 epochs, demonstrating strong generalization with minimal overfitting. Recent studies have more and more explored hybrid deep studying architectures combining Convolutional Neural Networks (CNNs) and Transformer models for imaginative and prescient duties, including gesture and signal language recognition. These works sometimes employ both feature concatenation, gated fusion, or additive mechanisms to mix local and global representations. In contrast, our method introduces a focused element-wise multiplication strategy that emphasizes mutual characteristic importance between global and hand-specific pathways.

In recent years, consideration mechanisms and Transformer-based models have gained traction in SLR due to their ability to give consideration to crucial parts of the input sequence. Transformer-based architectures, corresponding to Vision Transformers (ViTs) and BERT-style models, have been successfully utilized to sign language duties, bettering contextual understanding and feature extraction. Miah et al.10 proposed a novel strategy for sign language recognition that combines spatial–temporal consideration mechanisms with graph-based models and basic neural networks. Their mannequin is designed to capture both the spatial and temporal dependencies inherent in signal language gestures, making it notably efficient for recognizing dynamic sign language sequences. The graph-based approach models the relationships between totally different physique joints and their actions, whereas the spatial–temporal attention mechanism helps the model focus on the most important parts of the signal, bettering recognition accuracy.

We conducted qualitative inspections of misclassified samples and found that the majority errors occurred beneath excessive lighting conditions or partial occlusion of the hand. These findings are included to assist characterize the model’s failure modes and inform future enhancements, similar to incorporating temporal info or 3D hand pose estimation to enhance disambiguation of similar gestures. In Desk 9, the Proposed Hybrid Mannequin achieves superior results in comparability with other configurations.

This enchancment is basically attributed to the function suppression technique, which reduces background noise while preserving essential gesture info. To validate our hypothesis, we conducted an ablation study replacing background noise suppression with characteristic addition instead of element-wise multiplication. The outcomes indicate that our fusion technique consistently outperforms conventional methods, reinforcing the effectiveness of our hybrid Transformer-CNN architecture in real-world sign language recognition applications. In distinction to traditional CNN-based characteristic extraction, our proposed Hybrid Transformer-CNN model introduces a dual-path feature enhancement mechanism that eliminates background noise without requiring additional preprocessing or depth sensors.
