Blind people can learn to type by feeling the keys but they can't find and correct a mistake. In order to help blind people use a computer Dr. Tom Vincent has made a system that reads aloud what has been typed.
He added a voice to a cheap microcomputer. "The computer is programmed to repeat each letter as it is typed and to read what is displayed on the computer screen - it can be a letter, a word or whole sentences. It is programmed to pronounce English words. If a word is not in its memory the computer spells it. Any mistakes can easily be corrected. When the text is complete, a printed copy can be made in the usual way.
The system has won a prize and is already in use, so blind students at a college in Wales can use computers. Dr. Vincent is now working at an optical sensor that can recognize printed words and read them aloud.
