User-centred Design for an Open-source 3-D Articulatory Synthesizer

We describe our research direction to build a 3-D articulatory speech synthesizer. We are employing a usercentred design approach to develop the synthesizer. The end result will be added to the open-source research community. The system infrastructure we are planning is expected to allow for easy integration of current and future research results in vocal tract modelling and vocal sound production. In this paper, we identify the tasks that the speech synthesizer will support and the interface for using the speech synthesizer. Further, we hope that this paper will provide a call for participation from fellow researchers to contribute their results to this project.
