What is a phrase book designed for?

Some people give up trying to learn a foreign language. It can seem too much like hard work. But the problem comes when they go abroad on holiday and find they cannot communicate. How do they ask the way, order a cup of coffee, ask the price of something? There are, certainly, a lot of phrase books designed to help these people continue to live. In the phrase books they find all the right questions and some of the answers, too. But then, the problem is to be able to pronounce the phrases. If you don’t know French, Italian or English, how can you read out the right question in an accent that someone will understand? The printed work is not enough.
     Keith Chidwich thinks he has the answer to this problem, "I have got a phrase book which talks in different languages. I feel that I can go to any country in the world and talk with any foreigner. "he says. Keith is an inventor. His invention is an electronic device which produces phrases in four different languages: French, German, Italian and English. Unlike the phrase book, this device has a voice. It looks like a tape recorder.
