In this study the speaker characterising properties of two methods of representing pitch contours were compared. The first is Atal's (1972) approach, in which the entire intonation contour is divided up into 40 segments that form the input to data reduction and analysis techniques. The second method is a more analytical one, in which the contour is summarized by measurements that are related to 'key points' in the contour. The first approach turned out to yield superior recognition results. However, these results must probably be attributed to differences in the underlying phonological form and not to individual differences in the realisation of this representation. Keywords: speaker recognition.
