Alternância Vocálica das Formas Verbals e Nominais do Português Brasileiro para Aplicação em Conversão Texto-Fala
This paper investigates new strategies to deal with the alternation in vowel quality of the Portuguese spoken in Brazil for application in text-to-speech systems.
Based on an adequate identification of the grammatical classes, such as verbs and nouns, we have sought to solve such a problem. A general insight of the different phases needed to conceive a morphosyntactic parser as well as the main techniques for generating vowel alternation, in both general and restricted cases, are discussed. Test results showed that the vowel sound alternation rules proposed in
this paper solve most problems concerning the differences between verbs and nouns.
