Análise acústica da relação acento versus entoação no português falado em Mocajuba: contribuições para o Projeto Amper-Norte

Abstract

The present dissertation is part of AMPER-NORTE project (Atlas Prosódico Multimédia da Região do Norte do Brasil) and is linked to AMPER-POR project (Atlas Prosódico Multimedia do Português). Its main objective is to contribute to AMPER-NORTE project, featuring the dialectal prosodic variation of the Portuguese spoken in the urban area of Mocajuba (PA). The methodological procedures have been previously established by AMPER project.The corpus has been built with a speech sample of six informants, three males and three females: a woman (BF51) and a man (BF52) of elementary education, a woman (BF53) and a man (BF54) of middle education, a woman (BF55) and a man (BF56) of higher education, variety of Portuguese spoken in Mocajuba.Therefore, the corpus of the city of Mocajuba consists of 102 sentences of the type SVC (subject + verb + complement) with adjectival complement and indicators of place. Each sentence was repeated six times, totaling 612 sentences per informant. The analysis was made from data relative to the six informants. Therefore, 42 sentences were selected, 21 affirmative and 21 total interrogative with noun phrases simple or compound, they were selected to take account of the three accentual guidelines of Portuguese presenting a total of 14 oxytones, 14 paroxytones and 14 proparoxytone. The acoustic analysis of vowels was made in six stages and the results show that acoustic physical parameters of fundamental frequency (F0) and duration (ms) showed significant results for this analysis, confirming such parameters as complementary in the distinction of phrasal modalities in this range under study. The F0 becomes relevant, by moving on clamp format, which preferably occurs in the stressed syllable of the target word, nominal, in the three accentual guidelines and the duration shows that the accentual guidelines (oxytone, paroxytone and proparoxytone) recorded inversely proportional values and it is confirmed as a distinctive parameter. In the intensity, there was not enough satisfactory distinction to confirm it as complementary to F0 and ms in the variety of Portuguese spoken in Mocajuba.
