Lastly the construction of a more advanced model where the transfer of information is focused is discussed. Dialoque as cycles Fig.1 presents a sample dialogue and some rules to analyse it. The rules show the main types of utterances occurring in dialogue and their sequencing. The rules also show the basic grammatical structure. It may be convenient to start by looking at the sample dialogue.
Some utterances clearly belong together and consitute sections, rounds or cycles.
Utterances 1 and 2 make up one cycle consisting of a statement and a response. The response is called a backchannel item. In speech, the intonation contours would vary correspondingly. It is assumed that a dialogue consists of a series of cycles of this type - at least one. The types of cycles are given in rule 1, where certain terms are introduced.
