Movements of the head during speech are frequently observed to align systematically with acoustic and articulatory aspects of prosodic prominence, and are known to enhance perception when they occur (Munhall et al. 2004).  Recent studies employing electromagnetic articulometry (EMA), which supports direct comparison between speech acoustics, head movement and intraoral articulation, have greatly extended the precision of such observation (e.g. Garvin et al. 2025, Carignan et al. 2024, Tiede et al. 2019).  This talk will provide an overview of the methodology supporting such studies and review recent findings in this area.  The aim is to encourage discussion of possible mechanisms by which prosodic planning extends to recruitment of such co-speech head movements.
