This abstract presents an innovative method to create a Braille Embosser, which would be controlled by voice.The required embossed character will be provided by printer after giving the voice command.The technique would be most helpful for visually impaired people to perform their typing task.Creating a speech controlled printer using various electrical and mechanical domains such as digital signal processing, analog circuit design, and interfacing the electrical bobbins is the main objective of this project.Graphic printing is becoming more and more important in the life of blind people.Until now, unfortunately, braille printer can't print graphic.Thus, in this project, a graphic printing method for embosser has been introduced which utilizes voice recognition and edge detection to convert English alphabets to corresponding actual Braille language.Then, it utilizes faster scan method to read the input voice and print the graphic with dot style.This can achieve graphic printing with different sizes of image onto A4 paper clearly and completely.This voice controlled braille embosser can be used for identifying the graphic printing as well.
