Vocal and postural coupling in singing and speech. [link]Paper  doi  abstract   bibtex   
This study examines behavioral measures during speech and singing to assess the interaction of the postural control system and the production of expressive vocal behavior at different levels of vocal effort. We know that head motion is essential to both expressive speech and to balanced posture, suggesting that the head must be entrained to some extent by both subsystems simultaneously. This study shows that increased vocal effort (defined here as loudness) affects rigid body (6D) head motion and other measures of postural behavior acquired from force plates (6D) and video‐based motion analysis (2D). Specifically, as vocalizations becomes louder, the postural system becomes more simply coupled spatially and temporally to the vocal system.
