The analysis of authentic speech, unlike that of laboratory speech, needs to take into account the fact that the fundamental frequency patterns corresponding to the intonation of utterances can be of two types - local pitch characteristics determined by the surface phonological representation of the intonation and longer term characteristics corresponding to less well understood changes in pitch key and range. In this paper a number of acoustic correlates of changes in pitch key and range are examined and compared to subjective annotations and a preliminary attempt is made to estimate these changes automatically. 1.
