The main objective of this thesis is to carry out a geoprosodic mapping of three inquiry points of Brazilian Portuguese (PB) spoken in the Eastern Amazon: Belém (PA), Macapá (AP) and São Luís (MA), using modal intonation as the object of analysis. It is a study based on the assumptions of Sociophonetics (THOMAS, 2011) for understanding a speech acoustic analysis that considers the performance of social factors such as sex and schooling in describing the phenomenon analyzed. The interdialetal comparison of the three capitals comprises an acoustic analysis of the physical parameters of fundamental frequency (in st), duration (in Z-score) and intensity (in Z-score), observed in neutral declarative and interrogative sentences. For data collection, the methodology established by the AMPER project was used. The treatment of the data consisted of several stages, two of which are in line with the AMPER methodology: a) data coding; b) isolation of audios in individual files. The other steps were carried out with the support of scripts created by Albert Rilliard (LIMSI-CNRS), used in the automatic segmentation of the data, namely: c) script lance_batch_easyalign_v3.praat to obtain the textgrid of the .wav files; d) script of correction_segmentation.praat for phonetic segmentation in the praat program 6.0.39, e) script AMPER_Textgrid2Txt_V3_boucle_DepoisEasyAlign_v2.praat that generated the files with the acoustic parameters; f) normalization of acoustic parameters. With the treated data, the acoustic measurements of the parameters of fundamental frequency (f0), duration and intensity were obtained, which were organized in an Excel spreadsheet for later statistical treatment and graphing in software R. In order to validate the acoustic analyzes, twonon-parametric statistical tests were applied (Kruskal-Wallis and Wilcoxon) and the Post hoc test. For this research, speech samples were collected from eighteen speakers, stratified by sex, education (elementary, high school and university) and place. The total corpus consisted of 33 neutral declarative sentences and 33 total interrogatives, and the words used to compose the sentences contemplated the three accentuated staves of the Portuguese (stress on the last middle and first syllable and the extension of the sentences contains 10, 13 or 14 vowels, with sentences repeated six times by each speaker. In total there were 3.564 data analyzed (33 sentences x 2 categories x 3 best repetitions x 6 announcers x 3 places). This demonstrates that there are significant differences both for the place factor and for the social factors (sex and education of the speakers). The confronted capitals registered a similar prosodic pattern with respect to the variations of f0 in the acoustic characterization of the neutral declarative and total interrogative sentences. The results showed that the paraense, macapaense and ludovicense capitals followed the intonation pattern described for PB, with an elevation of the intonation peak in the pretonic and a drop of f0 in the stressed syllable in the neutral declarative modality (SILVESTRE, 2012). The total interrogatives showed lower f0 values in the pretonic ones with an increase in the final tonic, followed by a drop in the postonic ones when they existed, the circumflex pattern described by Moraes (1993) for PB. Regarding the intonational contour, the three capitals of the Eastern Amazon presented a similar f0 contour in the final noun phrase (SNF). On the other hand, there was a difference in the height of f0, since Macapá presented higher contours of f0 in the final stressed syllables, in the three accent staves, for the two phrasal modalities; while São Luís and Belém registered height of f0 approximate averages. The results of the acoustic analysis of the schooling factor showed that Macapá presented a greater variation of f0 in the three levels of education, in the three accentual guidelines of Portuguese for the two phrasal modalities. The duration parameter confirmed higher values in the tonic, with a similar production time in the two phrasal modalities, in the three mapped capitals, which is not a peculiarity of the modal intonation, but which is linked to the lexical accent. Variations in the intensity parameter are related to modal intonation. Therefore, the prosodic pattern of the target places found in this study behaves similarly to PB, since there was no difference in terms of modal intonation between the pattern verified in PB and the Portuguese spoken in the three capitals of the Eastern Amazon.

A variação prosódica em sentenças declarativas e interrogativas do português falado em Baião - Pará

This research is linked to the AMPER NORTH Project (Brazilian North prosodic multimedia atlas), which is part of AMPER – POR (Portuguese prosodic multimedia atlas). This study is going to contribute to constitute the Brazilian North multimedia atlas and its main goal is to characterize the Portuguese dialectal prosodic (variety spoken in the urban zone of Baião city PA). All the adopted methodological procedures follow the orientations settled by the general coordination of AMPER Project – POR. The corpus is composed by 06 informers and 66 phrases, syntactically structured in SVC (subject + verb + complement) and their expansions (adjectival syntagma and prepositional syntagma), obeying the same phonetic and syntactic restrictions and keeping the pattern of the corpora constituted by Portuguese varieties of AMPER Project – POR. The sentences of the corpus have 10, 13 and 14 vowels and all the phrases were repeated 06 times by each informer, constituting a total corpus of 396 phrases. The data of 06 informers were collected with three men and three women, from basic level of education medium level of education and higher level of education. Informers are aged between 35 and 75 years old. The selected corpus is constituted by 42 phrases – 21 declarative phrases and 21 interrogative – total ones, which compose the three accentual options of Portuguese. The declarative and interrogative modalities were analyzed on all the sentences and the acoustic analysis of the vowels were made in 06 parts. The analyzed acoustic parameters were: fundamental frequency (semitones), duration (ms) and intensity (dB). The results showed that the acoustic parameter of F0 is the most relevant to distinguish declarative and interrogative enunciations. It was noticed, as well on the final nominal syntagmas, as on the on the composed ones, a sound contour on the shape of a “griper”, on the last final nominal syntagma of the words and this movement shows that F0 is descendent for the declarative and ascendent to the interrogative modalities. We can understand that the duration complements F0 to distinguish the declarative and interrogative modalities. The intensity was not relevant to distinguish the modalities spoken in Baião city (PA).
