A Novel System For Blind, Deaf And Dumb People Assistant Using Raspberry Pi

In this world, the way of conveying information between deaf, dumb, and blind people and normal people is very difficult. It is very difficult to share their thoughts and information with others without any assistive devices. In the available scheme, the Arduino microcontroller is used to do some specific operations. It had some disadvantages, such as compiling time, execution time, and the microcontroller doesn't process speech to text conversion processes. In order to overcome the drawbacks faced in the available scheme, Raspberry Pi and sensors are used in the proposed scheme. With the help of the speech-to-text conversion process, deaf people can easily understand what normal people say. Also, there is no fear of traffic for blind people with the help of ultrasonic sensors, and with the accelerometer sensor, dumb people can easily convey their messages to normal people.
