You are a German living in Berlin. One day you’re walking down the street, minding your own business, when suddenly a stranger approached with a smile on his face. After stopping you, he holds a small electronic device close to his face and speaks slowly into it, saying, in English: “Can you tell me where I can buy some sauerkraut?” What should you do? (a) Run away; (b) Call the police; or, (c) Listen closely for the device to say, in German, “Konnen Sie mir bitte sager, which Sauerkraut Kaufen Kann?”
　　The most appropriate response would be (c) because the person in front of you is only a tourist trying to enjoy himself. The device is said to he the world’s first portable transistor—a hand-held microcomputer that—at the same time converts one spoken language into another.
　　The four-pound battery-operated product is called the Voice, and it is the creation of Advanced Products and Technologies an American electronics company. When the Voice is introduced in the United States in late April—at a price of $1,500—it will be capable of converting spoken English into Italian, German, French and Spanish. The product comes with separate cartridges (盒式储存器) for each of the four languages, which can be changed when the user travels from one country to another. The item will be sold in Europe soon after the U.S. Introduction, with cartridges that covert Italian, German, French and Spanish into English.
　　The Voice uses a microchip (微型集成块) and artificial Intelligence to translate Languages. It is started by voice command and produces voice output through a built-in speaker. Then the user makes a statement or asks a question, the Voice immediately repeats what has been said in another Language.
