their thoughts with other people. This design removes these difficulties and provides a system for communicating their message easily and solely and not just in the presence of a translator.
Abstract - Nowadays lack of ability to speak, hear, and see is
a genuine impairment. Those with these disabilities employ many techniques of communication with others. They are able to communicate in a number of ways, including sign language. Each word in sign language has a set of associated motions that can be utilized to convey a specific message through human body language. The main goal of this design is to convert sign language to voice and display through LCD by understanding human gestures. This is attained using Raspberry pi, camera, speaker, and LCD module. Consider, that a dumb person stands and performs in front of the camera and the system converts the gestures into speech and plays it through the speaker so that the blind can listen to it and the message is visible on the LCD so that the deaf person can see it. As a result, this system helps people with visual impairments and hearing impairments communicate with one another.

1. A Novel Approach for Communication among Blind, Deaf, and Dumb People Rohit Rastogi, Shashank Mittal, and Sajan Agarwal published in 2nd International Conference on “Computing for Sustainable Global Development”, 11th – 13th March 2015; IEEE Conference ID: 35071 This paper is going to concentrate on how to invent a new device that is useful for disabled people for communicating effortlessly with other normal people or people of their type. The objective is to develop the technology that can help individuals who are facing difficulty with blindness or deafness or speechlessness. So the Sharojan Bridge is developed and is based on the Wearable Technology in which the gadget can be worn by the person and thus makes the system smoothly movable. Here they used Texas0Instrumentation Circuitry and Arduino Circuit0Board to transmit messages between disabled people.

INTRODUCTION
Approximately 6 percent of the population in the world has a hearing disability. The proportion of this disability is 30 percent among persons over the age of 65 according to WHO figures. Deaf people with total hearing loss frequently use sign language. In this project, a deaf individual can communicate effortlessly using hand gloves that are attached to a flex detector which converts the sign language into speech using a microcontroller, and the text is displayed on an LCD. At present, the main problem faced by these disabled people is the communication part, to channel their thoughts

to other people. This system will help these people to overcome this problem by giving them support for communication. Sign language is used by speechless individuals for communication purposes. Sign language transmits messages using symbols, objects, or Gestures. The gesture is a pattern made by the loops and curvatures of the fingers.
In this project, there are 3 modules: blind module, dumb module, and deaf module. In a blind module, blind people will talk through the mic for communicating with other individuals. In this, they also have an app, in which the blind can do communication with the specific person in their contact by making his own gestures. In a deaf module, anyone can communicate with a deaf person using the terminal. They can write anything and it is shown on the terminal page to others. In a dumb module, sign language is considered a means to communicate.
Speech is the most effective and meaningful way in which we can share our opinions and feelings. Although, a huge part of the global population suffers from speech disorders. People with vocal disabilities face many difficulties to share
