Investigando desvozeamento vocálico no português brasileiro (PB) : análise acústica e perceptual das vogais altas pretônicas
(Universidade Federal do Pará, 2019-06-26) FAGUNDES, Giselda da Rocha; MEIRELES, Alexsandro Rodrigues; http://lattes.cnpq.br/9913871449747690; CRUZ, Regina Célia Fernandes; http://lattes.cnpq.br/3307472469778577
According to Gordon (1998), devoicing occurs in practically all the languages of the world he studied, including Brazilian Portuguese, being the high vowels more susceptible to the occurrence of the phenomenon that Gordon also associates with the deaf surrounding environment and atonicity. According to Meneses (2012, 2016), devoicing is related to the reduction in the magnitude of the vowel gesture, caused by the short articulation time, allowing the consonant gestures to overlap with the vowel gestures. Therefore, this PhD thesis investigates the phenomenon of the devoicing of the pretonic high vowels in Brazilian Portuguese (BP), both acoustically and perceptually, through the application of Gestural Phonology theory, taking into account the phonetic contexts that most favor this phenomenon. For acoustic analysis a total of 1,440 vehicle phrases were collected. For perception, 8,208 data were collected regarding identification and gradation, which, among other conclusions, converge with the results of Meneses (2012, 2016) and Hasegawa (1999), that is, that the devoiced vowels occur without prejudice to the perception of these vowels, which, like the devoicing, varies from individual to individual; and Gordon (1998), because the articulatory and aerodynamic factors that induce devoicing conflict with the perceptive factors, which advocate against devoicing, since, perceptually, there is no clear distinction between voiced and voiceless vowel, but a gradient between the extremes.

Padrão geoprosódico do português falado na Amazônia Oriental: análise comparativa de Belém, Macapá e São Luís

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.
