Real Time Implementation of Malayalam Braille Document Recognition System

Visually impaired people are integral part of the society and it has been a must to provide them with means and system through which they may communicate with the world. Malayalam Braille document evaluation system is an effective way to reduce communication gap between visually blessed and visionless people. The project focuses on converting the Braille document to Malayalam text and audio output. Here the focus is to convert entire Braille document page instead of character by character conversion. Concatenative speech synthesis technique is used for audio generation. A speech corpus will be created with Malayalam syllables. The syllables will be selected character wise and concatenated to generate output. The software used for simulation is Quartus II and the programming language used is VHDL. Software implementation of the project is done using MATLAB and Cyclone II FPGA is used for hardware implementation.
