ABSTRACT

Teeth morphology and oral cavity visualization through imaging techniques enables an accurate vocal tract assessment in speech research, especially when by Magnetic Resonance Imaging (MRI) [1].

Magnetic Resonance Imaging has been successfully applied on real-time analysis of the articulators during speech production, along the whole vocal tract, with good signal-to-noise ratio and without ionizing effects. As such, several MRI techniques provided the calculation of cross-sectional areas and volumes directly from static postures during sustained articulations [2] or using multiple repetitions [3, 4].
