In earlier studies the authors developed a model of German intonation based on the quantitative Fujisaki-model. The present study examines the influence of the segmental structure of an accented syllable on the timing of accent commands. It aims at developing refined alignment rules for speech synthesis. The corpus consists of 67 three-syllable words of German with word-accent on the second syllable produced by three male speakers three times. The words differ as to the structure of the second syllable. It was observed that onsets of accent commands can be most accurately predicted relative to the duration of the nuclear vowel, with variations depending on the type of consonant preceding the vowel. Accent command offsets are generally aligned with the offset of the syllable. The effectiveness of the refined timing rules was confirmed by an informal perception experiment.
