Our Braille writer includes a sound file for every letter of the English alphabet and numbers
through 1 to 0. When the user enters a letter in the way described above, the corresponding
sound for that letter will be played.
For example, when the user enters the letters, „T‟, „H‟, „I‟, „S‟, and then presses the space
key, the word “this” will be recognized and the corresponding sound will be played. After each
word recognized by the Braille writer, the user will be able to hear the word they just typed.
