Previous studies on a variety of languages have demonstrated that manual gesture is temporally aligned with prosodic prominence. However, the majority of these studies have been conducted on languages with word-level stress. In this paper, we investigate the alignment of manual beat gestures to speech in local varieties of Standard Indonesian, a language whose word prosodic system has been the subject of conflicting claims. We focus on the varieties of Indonesian spoken in the eastern part of the archipelago and Java. Our findings reveal that there is a strong tendency to align gesture to penultimate syllables in the eastern variety and a tendency to align gesture to final syllables in the Javanese variety. Additionally, while the eastern patterns appear to be word based, the Javanese pattern shows evidence of being phrase based. Surprisingly, the penultimate syllable emerges as a gestural anchor in the eastern variety even for two of the three speakers who showed little to no regular prosodic prominence on this syllable. This suggests that gestural alignment may serve to uncover prosodic anchors even when they are not employed by the phonology proper.
