Resumo
Várias vezes ouvimos falar que o português do Brasil é uma língua homogênea. Mas, um território de 8,5 milhões de quilômetros quadrados, com aproximadamente 200 milhões de pessoas, com grandes índices de analfabetismo e com uma pluralidade cultural - não poderia de modo algum apresentar uma língua homogênea. O presente estudo verifica como determinados falantes pronunciam os ditongos nasais -ões, -ães e –ãos, analisando os segmentos [ɐ̃], [õ], [ɪ̃] e [ʊ̃], que compõem estes ditongos nasais. O foco da pesquisa é através de uma investigação acústica. Verificadas as qualidades acústicas investigadas, a pesquisa faz uma análise comparativa entre as qualidades acústicas e articulatórias. A pesquisa utiliza o programa de análise acústica Praat. Com o auxílio do Praat e seguindo a Teoria Acústica de Produção de Fala de Fant (1960), foram feitas as segmentações apropriadas dos enunciados registrados e, para os segmentos relevantes, foi investigada a estrutura acústica dos formantes com as facilidades fornecidas pelo Praat. O objetivo da pesquisa está voltado para a forma como os falantes pronunciam os ditongos nasais. No estudo, foi levada em consideração a percepção do fator, já que surgiram variações inesperadas. Fonologicamente, a forma de plural dos ditongos nasais em estudo pode ser interpretada como /-awNS/.
Brazilians usually hear that his language is quite homogeneous. However, a large territory of 8,5 millions square kilometers, and with 200 million inhabitants, with a large contingent of his population not alphabetized, plus a cultural plurality, could not by all means be linguistically homogeneous. The present study verifies how some speakers pronounce the nasal diphthongs -ões, -ães e –ãos, with a particular articulatory and acoustic analysis of the diphthongal segments [ɐ̃], [õ], [ɪ̃] e [ʊ̃]. The focus of the research is the acoustic investigation. Once detected the acoustic patterns the work makes a comparative analysis between the acoustic and the articulatory patterns. The Praat Program is use for the acoustic analysis. With the help of Praat and following Fant speech acoustic theory (1960), there has been made the appropriate segmentations of the recorded utterances and for the relevant segments it has been investigated the formant structure with the facilities provided by Praat. The aim of the research is orientated towards how the speakers pronounce the nasal diphthongs. In the study it has been taken into consideration the factor perception, since there emerged unexpected variations. Phonologically the plural form of Portuguese nasal diphthongs may be interpreted as /-awNS/
