In this paper we present recent work on the development of Linguistic Models, resulting in a first "complete" articulatory-based TTS system for Portuguese. The system, based on TADA system, integrates our past work in automatic syllabification and grapheme-phone conversion plus a first gestural specification of European Portuguese sounds. The system was integrated with SAPWindows, an articulatory synthesizer for Portuguese. A demonstration of the system capabilities and a first perceptual evaluation are presented. © 2008 Springer-Verlag Berlin Heidelberg.5190 LNAI 101111Whalen, D.H.: Articulatory synthesis: Advances and prospects.
