A self teaching image processing and voice recognition based system is developed to educate visually impaired children,
chiefly in their primary education. System comprises of a computer, a vision camera, an ear speaker and a microphone.
Camera, attached with the computer system is mounted on the ceiling opposite (on the required angle) to the desk on
which the book is placed. Sample images and voices in the form of instructions and commands of English, Urdu
alphabets, Numeric Digits, Operators and Shapes are already stored in the database. A blind child first reads the
embossed character (object) with the help of fingers than he speaks the answer, name of the character, shape etc into the
microphone. With the voice command of a blind child received by the microphone, image is taken by the camera which
is processed by MATLAB® program developed with the help of Image Acquisition and Image processing toolbox and
generates a response or required set of instructions to child via ear speaker, resulting in self education of a visually
impaired child. Speech recognition program is also developed in MATLAB® with the help of Data Acquisition and
Signal Processing toolbox which records and process the command of the blind child.
