The human voice has essentially always played a part in music making; indeed, larger pipe organs have incorporated a Vox Humana stop for many years. Work on improving the naturalness of vocal synthesis using articulatory knowledge requires magnetic resonance imaging of natural vocal tract shapes and this has enabled 3-D printed models to be made. These can be stimulated with a quasi-larynx excitation signal and the possibility of a Vocal Tract Organ has emerged. This research report describes the current state of technical development of the Vocal Tract Organ and how it has been and could be used musically.
