Tongue, lip and jaw flesh-point movements were recorded together with the speech wave from two American English-speaking ventriloquists, each talking normally and then practicing their craft. These recordings were analyzed to describe and quantify changes in articulation arising from self-imposed perturbations of lip and jaw movements during ventriloquism. Results show a variety of apparent compensations involving changes in magnitude and timing of movements, and the positions of articulators. Some compensations are easy to understand from the perspective of a theory of speech production in which acoustic properties of speech sounds are a primary goal. Information from this study may have a practical benefit for disordered patients (e.g., with localized facial paralysis) who must maintain speech intelligibility in the context of diminished capacity for articulatory movements.
