Do you ever call long distance from a pay phone?
You dial the number, and then you hear something like: "Sixty cents, please. Please deposit(投硬币)sixty cents for the first three minutes."
If you are placing the call in New York State, don’t try to ask the operator a question. There is no one on the line with you. The voice you hear comes from a computer. It has vocabulary of seventy words in its memory. This program is known as the Automatic Coin Telephone Service.
The word and numbers are first recorded, each word and number by itself, by an actress. The sounds are then changed into electronic signal and stored in a computer memory circuit(电路). The circuit is hooked into the computer that controls all the calls made from pay telephones.
While you dial your call, the computer senses each of the numbers. When you finish, it calculates the cost, and produces the voice that you hear. As soon as you deposit the money, the computer automatically connects your call.
Have you ever called Information and heard an operator say: "Information. May I help you?"
You tell the operator a name and he or she gives you the phone number. In the past, the operator would have to thumb through the telephone directory to pick up the number. Now, a new computer system provides this information much more quickly. Sometimes it can find the number even if you misspell the name.
Information operators who use this new system type in the name you give on the computer terminal. In a flash, the computer displays the name and telephone number on the CRT(显像管). At the same time, the computer calls up nine similar names. In case you spelled the name wrong, the operator may still be able to find it.
All new phones are also entered into this computer system. The information operators, therefore, have the up-to-the-minute listings. At the end of the year, the computer is hooked to a machine that automatically sets the type for the new telephone directory. The directory is then printed from this type—accurately, quickly, and at a great savings in cost. [br] A computerized telephone is______the one that is not computerized.
