VocalTractLab 2.1b API for Matlab/Python (13 April 2015)

This API provides the possibility to use high-level functions of the VTL synthesizer from within your own software and comes with example scripts for Matlab and Python that illustrate its use. The API was compiled from the VTL 2.1 sources (with slight improvements of the acoustic synthesis) by Tino Sering, Max Murakami, and Anja Philippsen and kindly provided for download here.

Click here to download the API.

Please note that the included speaker file for a 1-year-old child and the according gestural score for the word "Mama" provided as examples are rather experimental. You are encouraged to try the API with the speaker file JD2.speaker and the gestural score example-hallo.ges or the examples included in the release of VocalTractLab 2.1 for Windows (see below).
