A nasalidade no dialeto quilombola do Norte de Minas: uma análise contrastiva baseada em corpus

This research investigated the nasality of vowels in the spontaneous speech of inhabitants of the quilombola communities of Brejo dos Crioulos and Poções (MG). As a theoretical framework, we based on the assumptions of Phonetics and Phonology, in renowned scholars on the investigation of nasality (CAGLIARI, 1977; CÂMARA JR., 1984, 2013; BISOL, 2013; ABAURRE; PAGOTTO, 1996; SILVA, 2015), with subsidies of the Corpus Linguistics. Its general goal was to investigate the occurrence of nasality, in the dialect of these quilombola communities, and their linguistic behavior, considering the linguistic factors that can interfere in the phenomenon. Specifically it was aimed to a) detect the occurrence of nasalized vowels with the help of the resources that the Corpus Linguistics provides (Praat and WorldSmith Tolls); b) discriminate the different types of occurring contexts of nasalized vowels; c) make quantitative and qualitative analyzes of the nasalized vowels in the study corpus; d) describe and analyze the behavior of nasalized vowels and; e) contrast the values of F1 and F2 of the oral and nasalized vowels. It was hypothesized that the nasality happens because it is conditioned by the nasal segment following the nasalized vowel - phonological process of “assimilation” - its position as the primary stress and grammatical category. It was believed that the quilombolas communities of Brejo dos Crioulos and Poções produce nasalized vowels in their speech and this linguistic phenomenon is favored by the adjacent presence of consonants or nasal vowels. Furthermore, it was hypothesized that the values of F1 and F2 of oral and nasalized vowels in these communities are distinct. The following research questions were elaborated: (i) is the presence of nasalized vowels in the speech of these quilombola communities conditioned to the presence of a nasal sound segment? (ii) does the nasal sound segment following the nasalized vowel favor the occurrence of the nasality phenomenon? is there a difference between the values of F1 and F2 of the oral and nasalized vowels in both quilombola communities considered? To compose our corpus, 24 interviews recordings were used (12 female speakers and 12 male speakers), a total of 24 participants. It was found that the following nasal sound segment tends to condition the nasalized vowel. In general, it assimilates the lowering of the soft palate of nasal consonant segment immediately following, but there are cases of nasal vowel segment - regressive assimilation; the stressed syllable tends to favor the nasality, but it occurs in pretonic and postonic position as well; F1 and F2 values of oral and nasalized vowels in the quilombola communities of Poções and Brejo dos Crioulos are distinct: the group of Brejo dos Crioulos tends to produce the F1 of oral and nasalized vowels more lowered than the group of Poções and the F2, in a more anterior position. The nasality tends to occur in verbs and nouns, although it is not specific to a grammatical category. This research found cases of spurious nasalization, confirming previous studies. In turn, it revealed cases of lexical items with favorable context for nasalization, but with its non-occurrence. This last case, considered as the lowering of the uniform soft palate in PB, presented pronounced vowels without the soft palate lowering. That is, it was detected variation in the phenomenon of nasalization in PB. With this work, it was promoted the discussion about nasality, in order to contribute to the linguistic studies about the functioning of Brazilian Portuguese in this geographical context.

Who is in charge? An L2 Discourse Intonation Study on Four Prosodic Parameters to Exert the Pragmatic Function of Dominance and Control in the Context of L2 Non-specialist Public Speaking

This paper reports the findings from a study of the learning of English intonation by Spanish speakers within the discourse mode of L2 oral presentation. The purpose of this experiment is, firstly, to compare four prosodic parameters before and after an L2 discourse intonation training programme and, secondly, to confirm whether subjects, after the aforementioned L2 discourse intonation training, are able to match the form of these four prosodic parameters to the discourse-pragmatic function of dominance and control. The study designed the instructions and tasks to create the oral and written corpora and Brazil’s Pronunciation for Advanced Learners of English was adapted for the pedagogical aims of the present study. The learners’ pre- and post-tasks were acoustically analysed and a pre / post- questionnaire design was applied to interpret the acoustic analysis. Results indicate most of the subjects acquired a wider choice of the four prosodic parameters partly due to the prosodically-annotated transcripts that were developed throughout the L2 discourse intonation course. Conversely, qualitative and quantitative data reveal most subjects failed to match the forms to their appropriate pragmatic functions to express dominance and control in an L2 oral presentation.

Valores de referência de parâmetros acústicos para a voz normal no português europeu

O presente estudo tem como objetivo a caraterização acústica da voz normal para os falantes do Português Europeu, em termos de frequência fundamental, jitter, shimmer e relação sinal-ruído. São também analisadas as caraterísticas individuais que possam ter influência sobre a qualidade vocal, nomeadamente idade, género, índice de massa corporal, hábitos tabágicos e uso da voz no canto. Para tal, foram recolhidas amostras de fala de 363 indivíduos com uma voz avaliada como normal: 113 homens e 250 mulheres com idades compreendidas entre os 18 e os 91 anos. Amostras da produção sustentada da vogal /a/ foram analisadas acusticamente com o programa Praat, tendo sido extraídos os valores da média, mediana e desvio-padrão da frequência fundamental, jitter (ppq5), shimmer (apq11) e relação sinal-ruído. Os resultados obtidos apontam no sentido do género e a idade do indivíduo serem os fatores que maior influência exercem na voz, sendo que ambos os géneros apresentam um declínio da qualidade vocal ao longo da vida. As mulheres, globalmente, apresentam valores de frequência fundamental de 193,4±28,5 Hz (média ± desvio padrão da média), significativamente mais elevados que os homens, com valores de 120,7±22,3 Hz. Em termos de jitter, as mulheres obtiveram valores de 0,214±0,126 %, significativamente mais reduzidos que os 0,247±0,190 % obtidos para os homens. O shimmer não apresentou diferenças significativas entre géneros, sendo que os valores apresentados foram de 5,403±2,652 % para homens e 5,174±2,696 % para as mulheres. Relativamente à relação sinal-ruído, foram obtidos valores significativamente mais elevados nas mulheres, com 17,335±3,958 dB, tendo-se obtido para os homens 16,315±3,267 dB. Não foi encontrado um efeito significativo do índice de massa corporal, hábitos tabágicos e uso da voz no canto. Este trabalho disponibiliza novos dados para que a avaliação da voz em contexto clínico seja mais objetiva e eficaz.

The role of musical aptitude in the pronunciation of English vowels among Polish learners of English

It has long been held that people who have musical training or talent acquire L2 pronunciation more successfully than those that do not. Indeed, there have been empirical studies to support this hypothesis (Pastuszek-Lipińska 2003, Fonseca-Mora et al. 2011, Zatorre and Baum 2012). However, in many of such studies, musical abilities in subjects were mostly verified through questionnaires rather than tested in a reliable, empirical manner. Therefore, we run three different musical hearing tests, i.e. pitch perception test, musical memory test, and rhythm perception test (Mandell 2009) to measure the actual musical aptitude in our subjects. The main research question is whether a better musical ear correlates with a higher rate of acquisition of English vowels in Polish EFL learners. Our group consists of 40 Polish university students studying English as their major who learn the British pronunciation model during an intense pronunciation course. 10 male and 30 female subjects with mean age of 20.1 were recorded in a recording studio. The procedure comprised spontaneous conversations, reading passages and reading words in isolation. Vowel measurements were conducted in Praat in all three speech styles and several consonantal contexts. The assumption was that participants who performed better in musical tests would produce vowels that are closer to the Southern British English model. We plotted them onto vowel charts and calculated the Euclidean distances. Preliminary results show that there is potential correlation between specific aspects of musical hearing and different elements of pronunciation. The study is a longitudinal project and will encompass two more years, during which we will repeat the recording procedure twice to measure the participants’ progress in mastering the English pronunciation and comparing it with their musical aptitude.

Alteraciones en la voz de las pacientes con anorexia nerviosa restrictiva: un estudio piloto

Se realiza un estudio sobre el tono (percepción acústica) de la voz en la anorexia nerviosa restrictiva (ANR). El objetivo es valorar la alteración en la voz de las pacientes con ANR cuando el trastorno se inicia en la pubertad. La muestra total son 148 sujetos distribuidos en dos grupos: grupo control (n = 102) y ANR (n = 46). Se determinó la frecuencia fundamental de la voz (F0) utilizando dos fonemas ("a" e "i") mediante un micrófono Plantronic 300 y grabador digital. Se analiza la voz con el programa Praat. Se presentan los primeros datos para la lengua española de los valores normales de la F0 de voz en población femenina sana de 9 a 17 años. Posteriormente se muestran los datos comparativos con el grupo de pacientes con ANR.

Contribución al atlas prosódico de Canarias (AMPER-Can) : declarativas e interrogativas de La Gomera (Islas Canarias)

AMPER (Atlas Multimedia de Prosodia del Espacio Románico), nacido en el año 2002 en Francia, pretende realizar un atlas de prosodia de las lenguas y variedades lingüísticas del ámbito románico y hacer estudios descriptivos que permitan la comparación entre ellas. Dentro de este macroproyecto se sitúa AMPERCan, subproyecto que se ocupa del estudio geolingüístico de la prosodia del español de Canarias para contribuir a la confección del Atlas con la aportación de los datos prosódicos de este punto de España. En este marco, la presente tesis doctoral pretende describir las características fonéticas y fonológicas de un conjunto de oraciones declarativas neutras con sentido completo e interrogativas absolutas extraídas de un corpus experimental y espontáneo emitido por informantes de la isla canaria de La Gomera. El análisis acústico se realizó con MatLab y Praat y los valores absolutos de F0, duración e intensidad obtenidos fueron relativizados para determinar su importancia perceptiva a partir del umbral diferencial de 1,5 semitonos (F0), 36% (duración) y 3 dB (intensidad). El objetivo de este estudio es doble: 1) En primer lugar, trataremos de comprobar si la entonación de esta variedad canaria dista sustancialmente de la descrita para el español de las otras islas, estableciendo las posibles diferencias entre las variables lingüísticas y extralingüísticas consideradas. Desde el punto de vista lingüístico el habla gomera presenta rasgos más conservadores y, asimismo, afines al español de América debido a la confluencia de determinados factores históricos. 2) En segundo lugar, contribuiremos a la confección del Atlas completando seis fases de estudio correspondientes a la isla objeto de investigación distribuidas en dos puntos de encuesta: San Sebastián y Valle Gran Rey.
