Vowels are synthesized using vocal tract solid models, demonstrating functions of the vocal tract and vocal cords waves. The models were shaped based on 3D MRI and stereolithography (Rapid Prototyping), and glottal waves are generated using Rosenberg-Klatt waveform with 1/f fluctuation of its cycle. Male and female models are used to produce vowels. Voice qualities are well enough to identify the persons whom MR images were taken from.
