Chapter two has a new initial section but otherwise remains as it was. Chapter three incorporates a new section on pause and how this interacts with rhythm, and rather more on the function of stress. Chapter four has an extended initial section but otherwise remains largely as it was. Chapter five on intonation contains several sections which have been rewritten to varying extents. Chapter six of the first edition has disappeared: in 1977, very little work had been published on fillers and it seemed worthwhile incorporating a chapter that sat rather oddly with the phonetic/phonological interests of the rest of the book. Not that there is a great industry of descriptions of the forms and functions of these and similar phenomena there seems no reason toretain this early but admittedly primitive account.
