Computers have many uses today. Computer can solve difficult problems and control complex machines. Many people use small computers called calculators to add, subtract, multiply, and divide numbers quickly. Scientists use large computers to solve many problems at the same time. You can play games with computers, and some computers can help you learn languages. The Kurzweil Reading Machine is a special kind of computer. It can read books for blind people.
The Kurzweil machine consists of three components: a scanner, a computer, and a voice synthesizer (电子音响合成器). These three parts are like your eyes, your brain, and your voice. The scanner is the "eye" of the machine. It scans, or looks at, the words on the page of a book and changes them into digital signals. These digital signals then go to the computer, the "brain" of the machine. The computer analyzes the signals and recognizes the words. The computer sends information about the words to the voice synthesizer. The voice synthesizer makes the sounds of the words.
To use the machine, a blind person simply opens the book and puts it face down on the scanner (like a photocopy machine). The machine "reads" the words on the page. When one page is finished, the blind person turns the page and puts the book on the scanner again. The Kurzweil machine can read in a normal voice or in a special fast voice. It can read words with small letters, large letters, or italics (斜体字).
Blind people like the Kurzweil machine because they can, "read" anything with it: newspapers, magazines, books, and even typed letters. Many libraries now have Kurzweil machines for blind people to use.
