Previous studies on utterance-level intonational trends have focused mainly on fundamental frequency (f0), but there is some evidence that other phonetic properties also play a role. The subglottal pressure and intensity variations have been argued to be involved in intonational trends. However, little is known about the dynamics of the intensity trend in intonational contrasts and its relationship with the f0 trend. The current study examines the dynamical patterns of intensity and f0 in declarative and polar question utterances in a Bantu language called Embosi. The results show that both f0 and intensity exhibit initial rising and final lowering, but their kinematic profiles do not always match. To account for the current findings under the framework of articulatory phonology, we propose a pulmonic pressure initiation unit in addition to intonational tone units at the utterance level.
