An animated realistic head with vocal tract for the finite element simulation of vowel /a/

Marc Arnela, Leonardo Pereira-Vivas, Jorge Egea

Three-dimensional (3D) acoustic models can accurately simulate the voice production mechanism. These models require detailed 3D vocal tract geometries through which sound waves propagate. A few open source databases typically based on magnetic resonance imaging (MRI) are already available in literature. However, the 3D geometries they contain are mainly focused on the vocal tract and remove the head, which limits the computational domain of the simulations. This work develops a unified model consisting of an MRI-based vocal tract geometry set in a realistic head. The head is generated from scratch based on anatomical data of another subject, and contains different layers that add an organic appearance to the character. It is then not only designed to allow accurate finite element simulations of vowels, but more importantly, it can also be animated to add a realistic visual layer to the generated sound. This is expected to help in the dissemination of results and also to open potential applications in the audiovisual and animation sector. This paper shows the first results of the model focusing on the vowel /a/.
