As said above these codes solves the problems and computer speaks the solutions. It also used OCR to detect the sudoku puzzle from a given image. But that worked only for the given bmp image. :( Other files are not working . Obviously that is a bug, i hope other matlab hobbyists will work on it.. Moreover I wanted to solve these solutions from webcam too! but unfortunately that's not working. How I developed the code? Actually I downloaded the m files of Video Sudoku solver and Text 2 speech files in the file exchange. Edited some codes and added both codes in the same m file. I Hope this file will be developed more . Thanks :)
