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.

The phonograph was invented quite by accident. In 1876 Thomas Edison moved to Menlo Park, New Jersey, where he established an industrial research laboratory. There Edison worked on a carbon telephone transmitter to improve the existing Bell system.
In that laboratory a year later Edison invented the phonograph while trying to improve a telegraph repeater.
He attached a telephone diaphragm to the needle in the telegraph repeater to produce a recording that could be played back. After some improvements to the machine he recited “Marry Had a Little Lamb” and played the recognizable reproduction of his voice back to the astonished audience.
