Abstract

Even though the hearing and vocally impaired populace rely entirely on Sign Language (SL) as a way of communication, the majority of the worldwide people are unable to interpret it. This creates a significant language barrier between these two categories. The need for developing Sign Language Recognition (SLR) systems has arisen as a result of the communication breakdown between the deaf-mute and the general populace. This paper proposes a Hybrid Convolutional Recurrent Neural Network-based (H-CRNN) framework for Isolated Indian Sign Language recognition. The proposed framework is divided into two modules: the Feature Extraction module and the Sign Model Recognition module. The Feature Extraction module exploits the Convolutional Neural Network-based framework, and the Model recognition exploits the LSTM/GRU-based framework for Indian sign representation of English Alphabets and numbers. The proposed models are evaluated using a newly created Isolated Sign dataset called ISLAN, the first multi-signer Indian Sign Language representation for English Alphabets and Numbers. The performance evaluation with the other state-o- -the-art neural network models have shown that the proposed H-CRNN model has better accuracy.
