In the first part of this study, we measured the alignment (relative to segmental landmarks) of the low F0 turning points between the accentual fall and the final boundary rise in short Dutch falling-rising questions of the form "Do you live in [place name]?" produced as read speech in a laboratory setting. We found that the alignment of these turning points is affected by the location of a postaccentual secondary stressed syllable if one is present. This is consistent with the findings and analyses of Grice, Ladd, & Arvaniti, 2000 ("Phonology" 17, 143-185), suggesting that the low turning points are the phonetic reflex of a "phrase accent." In the second part of this study, we measured the low turning points in falling-rising questions produced in a task-oriented dialog setting and found that their alignment is affected in the same way as in the read speech data. This suggests that read speech experiments are a valid means of investigating the phonetic details of intonation contours. (Contains 4 tables, 4 figures and 7 footnotes.)
