Sandra Moreira Rua Ventura; Diamantino Rui da Silva Freitas; João Manuel Ribeiro da Silva Tavares

The speech production has always been a subject of interest both at morphologic and acoustic levels. This knowledge is useful for a better understanding of all the involved mechanisms, and for the construction of articulatory models. Magnetic resonance imaging (MRI) is a powerful technique that allows the study of the whole vocal tract, with good soft tissues contrast and resolution, and permits the calculation...
