BrailE- Reading Device for the Deaf and Blind in Real Time Speech

ABSTRACT Braille is a vital means of communication; it is a system for blind people, one of touch reading and writing in which Raised dots are impressions that represent the letters of the alphabet. It is an extremely important tool for blind people to educate themselves, and it is a critical component that supports not only educational advancement, but subconsequently increases employment prospects. The blind should be taught Braille to be able to become literate, which is a necessity in today's world. Braille is a much harder language than sign, as there are a lot of combinations of the impressions of the six raised dots that are not easy to memorize. Visually impaired people are required to master skills to communicate through Braille text, which itself is really time-taking and cumbersome task. In addition, other people need to learn the same set of skills to understand and respond to the visually impaired person. We have devices that convert text to Braille language as well as real-time Braille to speech using Raspberry Pi camera and a Raspberry Pi. Other devices use FPGAs/Arduinos for converting speech to braille. This paper is a survey of different techniques that were used for the conversion of text to braille and vice versa, and an evaluation of the accuracy of these methods is done.
