This study compares the intonational realizations of reading style as well as story-telling in German and Brazilian Portuguese (BP). By applying the Fujisaki model we can examine the frequencies and alignments of tonal transition, the so-called tone switches. Analysis of accent commands from the different corpora shows that in German 75% of commands can be associated with automatically generated stress labels. In comparison, manually assigned prominence labels can account for 80% of commands. This latter figure is much lower for BP (61%). This suggests that in BP prominence is signaled by F0 cues to a lesser degree. In both languages story-telling is associated with fewer accented syllables, a higher rate of rising tone switches on stressed syllables and a broader distribution of accent command amplitudes than reading style.
