Communication is always having a great impact in every domain and how it is considered the meaning of the thoughts and expressions that attract the researchers to bridge this gap for every living being.
The objective of this project is to identify the symbolic expression through images so that the communication gap between a normal and hearing impaired person can be easily bridged.

3. Introduction
● The world is hardly live without communication, no matter
whether it is in the form of texture, voice or visual
expression.
● The communication among the deaf and dumb people is
carried by text and visual expressions.
● Gestural communication is always in the scope of
confidential and secure communication.
● Hands and facial parts are immensely influential to express
the thoughts of human in confidential communication.

4. Motivation
● Sign language is learned by deaf and dumb, and usually it is
not known to normal people, so it becomes a challenge for
communication between a normal and hearing impaired
person.
● Its strike to our mind to bridge the between hearing
impaired and normal people to make the communication
easier.
● Sign language recognition (SLR) system takes an input
expression from the hearing impaired person gives output to
the normal person in the form text or voice.

5. Problem Statement
● Understanding the exact context of symbolic
expressions of deaf and dumb people is the
challenging job in real life until unless it is properly
specified.

1/17/2019 9
● We analyze 4,800 images of sign images which is ISL of the English alphabet,
which have a spread of 26 class labels assigned to them. Each class label is a set of
sign images of the English alphabet.
● All the images are resized to 640 x 480 pixels, and we perform both the model
optimization and predictions on these downscaled images.

19. Conclusion and Future Work
● In this project, we proposed an idea for feasible
communication between hearing impaired and normal person
with the help of deep learning and machine learning approach.
● This proposed work ensures the accuracy of 91.22% using
SVM, 95.71% using Random Forest, 87.54% using KNN,
98.74% using CNN and 99.79 using AlexNet.
● There is ever the sounding challenge to develop a sign
language system in data the collection remains invariant of the
unconstraint environment. This project can be extended to the
real time data.
