In this paper work, past, present and future, in articulatory synthesis applied to Portuguese is presented 1 .
In this paper new EMMA data regarding European Portuguese nasals is presented. Some details about corpus constitution, recording and annotation is given. First results from analysis are presented. Quantitative analysis of velum movement was done for nasal vowels between stops. For the other contexts representative examples are presented and qualitatively… (More)
A new articulatory synthesizer (SAPWindows), with a modular and flexible design, is described. A comprehensive acoustic model and a new interactive glottal source were implemented. Perceptual tests and simulations made possible by the synthesizer contributed to deepen our knowledge of one of the most important characteristics of European Portuguese, the… (More)
In this paper we study the effect of source changes, caused by vocal tract load, in perception of nasality. For that we have developed an articulatory speech synthesizer, including a comprehensive nasal tract model and an interactive glottal source model. Our main objective was to investigate to what extent is necessary, in systems aimed to produce high… (More)
Mondor's disease is a rare entity characterized by sclerosing thrombophlebitis classically involving one or more of the subcutaneous veins of the breast and anterior chest wall. It is usually a self-limited, benign condition, despite of rare cases of association to cancer. We present the case of a 32 year-old female, breast-feeding, who went to emergency… (More)
In this work it is described a software tool implementing the Klatt synthesiser to be used on a teaching laboratory. The user interface allows an easy edition of the synthesis parameters, thus the student may quick and easily change the phonetic characteristics of a vowel and listen to the result or seeing its time or frequency properties.
