This book presents a framework for the linguistic analysis of speech and a computer program to process the results of this analysis. The model of description for the linguistic analysis is that known as `scale-and-category¿ grammar. It is particularly suited for a study of how people use their language, and especially for a sociologically-oriented study of linguistic behaviour. The computer program analyzes the grammatical structures written in a linear notation. A second version has been written which allows easy modification to handle a variety of grammatical schemes, and the program has application to the processing of the analysis of sequential behaviour in general, especially where there are complex relations between the units analyzed.
