Wave
The Wave Speech Research System is a 3D motion capture system specifically designed for tracking speech related articulatory orofacial movements.
The Wave system uses an electromagnetic field to track and record the tiny movements associated with speech, the rising and lowering of the jaw, the protrusion of the lips, etc.
The speaker is situated within a 50x50x50 cm area in front of an electromagnetic generator, and does not have to keep still as long as she/he stays within the given area. Light and tiny coils are placed on the areas of interest, chin and lips for instance. A sound recording takes places simultaneously and is synchronized with the spatial measurements. The result consists of a file where the movements are expressed as numbers for three dimensions together with a sound file.
The Wave System is presently situated in one of our soundproof Video studios, with the benefits of an adjoining control room and with sufficient space in the recording studio for the 3D motion capture system.
