In this work we present a recently acquired MRI database for European Portuguese. As a first example of possible studies, we present results on 2D and 3D analyses of European Portuguese nasals, particularly nasal vowels. This database will enable the extraction of 2D and/or 3D articulatory parameters as well as some dynamic information to include in articulatory synthesizers. It can also be useful to compare the production of European Portuguese with the production of other languages and have further insight on some of the European Portuguese characteristics, as the nasalization and coarticulation. The MRI database and related studies were made possible by the interdisciplinary nature of the research team, comprised of a radiologist, image processing specialists and a speech scientist.
