Abstract
As human being’s communication is a very crucial part of our life, it is essential for sharing thoughts and ideas for our survival. But unfortunately for the speaking and hearing-impaired minority, it is difficult or impossible to communicate through speech. But most of the common people have no knowledge about sign language and its interpretations. This is one of the major problems faced by these kinds of people during their communications. Getting an interpreter is not easy every time. To solve this issue, a model is developed using neural networks for finger-spelling based on the various hand gestures. In this user-independent model, CNN-based models are trained using a set of image and hand skeleton datasets. The skeleton dataset is created using the hand image dataset and is done to improve the accuracy of the model. By using this model, a speech-impaired person can easily communicate with a person who has no knowledge of it, the model translating the hand gestures to sentences in English. The main issue with the current system is that there are some groups of alphabets, whose sign language symbols look alike. This makes the image-based classification model a bit difficult to correctly classify and the accuracy of the prediction can also be low. This issue can be solved using a hand skeleton classifier. As in the hand skeleton image, the position and structure of each finger can be identified more accurately than from an image. This makes the neural network model to learn better and can classify with higher accuracy of about 98.6.
