title: The velic traverse: an independent oral articulator?
abstract: Two speech functions have traditionally been ascribed to the velum: opening and closing the velopharyngeal port and providing a passive surface against which the tongue can produce oral constrictions. Contrary to this passive oral function, the present x-ray study finds that a substantial portion of the velum moves to constrict the oropharyngeal isthmus for French uvular /ʁ/. This substructure, designated the velic traverse, functions independently of the parts of the velum used for velopharyngeal port closure, thus acting as an oral articulator. An active velic traverse challenges methods for estimating vocal tract shapes based on tongue posture alone.
