Are glottalic mechanisms in Human Beatboxing really glottalic ?

Résumé

This communication focuses on the production of ejectives and implosives in Human Beatboxing (HBB). To investigate ejectives and implosives (i.e. glottalic mechanisms), real-time Magnetic Resonance Imaging data was collected on one professional subject. MRI recordings were analyzed via a functional Principal Component Analysis of vocal tract contours. The findings show that glottalic mechanisms for this subject are produced with tongue root and velo-pharyngeal maneuvers to change the volume of the pharyngeal cavity rather than laryngeal raising or lowering. We think ejectives and implosives might better be described as obstruent consonants produced with pharyngeal compression or expansion and a closed glottis at least in Beatboxing.
