This paper investigates the relationship between syllabic duration and F0 contours for implementing three prosodic functions. Work on rhythm usually describes the evolution of syllable-sized durations throughout utterances, rarely making reference to melodic events. On the other hand, work on intonation usually describes linear sequences of melodic events with indirect references to duration. Although some scholars have explored the relationship between these two parameters for particular functions, to our knowledge, there has been no investigation on the systematic correlation between syllabic duration and F0 values throughout narrative sequences. Based on a corpus of story retelling with nine speakers of Brazilian Portuguese from two regions, our work investigated the interplay between syllabic duration and melody to signal three prosodic functions: terminal and non-terminal boundary marking and prominence. The examination of local syllabic duration maxima and four F0 descriptors revealed that these maxima act as landmarks for particular F0 shapes: for non-terminal boundaries, the great majority of shapes were increasing and increasing-decreasing patterns; for terminal boundaries, almost all shapes were decreasing F0 patterns; and for prominence marking, the great majority of shapes were high tones across the stressed syllable. Time series analyses revealed significant correlations between duration and specific F0 descriptors, pointing to a ruled interplay between F0 and syllabic duration patterns in Brazilian Portuguese story retelling
