The model was obtained from the magnetic resonance images (MRI), taken during the subject phonation by the method of rapid prototyping. The random excitation was applied at the vocal folds and the response was measured along the vocal tract. The frequency response functions were evaluated by a global identification method. The resulting eigenfrequencies (formants) and the acoustic mode shapes of vibration are compared with the acoustic measurements carried out during the MRI realization.
