An MRI study of European Portuguese nasals



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 synthesiz- ers. It can also be useful to compare the production of European Portuguese with the production of other languages and have fur- ther insight on some of the European Portuguese characteristics, as the nasalization and coarticulation. The MRI database and re- lated studies were made possible by the interdisciplinary nature of the research team, comprised of a radiologist, image process- ing specialists and a speech scientist.
