VocalTractLab3D - Special version for 3D acoustic simulation (29 Sept. 2022)

This is a special version of VTL derived from the previous version 2.3. Here, a 3D acoustic simulation based on the multimodal method has been added, which can be controlled via a separate page in the GUI. This extension has been implemented by Dr. RĂ©mi Blandin while working with Peter Birkholz' group for the project "Wideband acoustic modeling of speech" funded by the German Research Foundation (DFG, grant BI 1639/7-1). Click here to download a ZIP file containing the executable GUI version including the source files, and a user guide. To download the user guide only, which explaines the new 3D acoustic simulation, click here.
