Abstract
The ModaVox program was developed to study acoustic propagation of vowel sounds in a 3D vocal tract by using the transmission line matrix (TLM) method. The name ModaVox stands for “Modelador da Voz” in Portuguese, or Voice Modeler in English. At the present moment, it is able to build and solve 3D TLM numerical models of the vocal tract. The meshes are constructed over the voxels (volumetric picture elements) in segmented medical image sequences. The segmentation of the images is performed via a neural network, island removal and some manual adjustments with the ModaVox’s toolboxes. An implementation of the TLM method allows for the simulation of the acoustic propagation of the input signal through the TLM mesh of the vocal tract model. ModaVox also generates tetrahedral and or surface triangle meshes.
