| We arrived in Naples on the Sunday
night, and spent the night on the ship. The next morning we went ashore. We
weren’t leaving again till six o’clock that evening, so we had the day to see
Naples. Well, we walked around the streets a bit, and looked at this and that.
And then I wanted to see the ruins of Pompeii, of course. I saw a taxi, and we stopped it, and asked the taxi-driver to take us to Pompeii. He said something, and shook his head. We couldn’t understand what was going on. You know what taxi-drivers are alike, all over the world. Eitherit’s too far, or too close, or the wrong dis- trict, or they’re just going home to dinner, or they don’t know the place you are talking about, or they can only take you there if you pay a special rate.

{{B}}TEXT A{{/B}} As well as the problems concerned with obtaining good quality audio recordings, recording also raises important theoretical problems. The main problem is usually referred to as the observer’s paradox. Ideally we want to know how people use language when they are not being observed. When speakers know they are being observed, their language shifts towards more formal styles, probably rather erratically, as not everything in language is under equal conscious control, and as speakers probably go through cycles of half forgetting they are being recorded. So the most casual language is the most difficult to record. The language that linguists would most like to be able to record is the language which is most susceptible to contamination by observation. With modem audio-recording equipment, there is, of course, no difficulty in recording speakers in many face-to-face situations or on the telephone.
