The current study examines the relationship between prosodic accent labels assigned in the Kiel Corpus of Spontaneous Speech IV, Isaˇcenko’s intoneme classes of the underlying accents and the associated parameters of the Fujisaki model. Among other findings, there is a close connection between early peaks and information intonemes, as well as late peaks and non-terminal intonemes. The majority of tokens within both intoneme classes, however, are associated with medial peaks. Precise analysis of alignment shows that accent command offset times for information intonemes are significantly earlier than for non-terminal intonemes. This suggests that the anchoring of the relevant tonal transition could be more important for separating different intonational categories than that of the F0 peak.
