We are developing a software system to help the study of Portuguese Vowel Production. This tool is an articulatory synthesizer with a graphical user interface. The synthesizer is composed of a saggittal articulatory model derived from Mermelstein model and a frequency domain simulation of the electric analog of the acoustic tube. User can easily define the nasal tract configuration. System includes optimization by simulated annealing to perform acoustic-to-articulatory mapping. In this paper we present the system being developed, its current state and future perspectives. Preliminary experiments with Portuguese Vowels gave good results.
