Resumo: Este trabalho tem por objetivo comparar a prosódia utilizada em sentenças declarativas e interrogativas no português brasileiro (falado nas cidades de Belém, Belo Horizonte, Florianópolis e São Paulo) e no português europeu – falado nas cidades de Vinhais (continente), Fenais (ilhas Açores) e Calheta (ilha da Madeira). Foram explorados acusticamente os parâmetros de frequência fundamental, duração e intensidade em 252 enunciados que figuram no corpus AMPER-Por. Os movimentos melódicos pré-nuclear, nuclear e final foram observados e permitiram encontrar algumas diferenças entre o português brasileiro e o europeu, principalmente aquele falado nas ilhas. Em relação à duração, a principal diferença entre o português brasileiro e o europeu consiste na maior duração nos dados do Brasil. A intensidade não se mostrou um parâmetro relevante para diferenciar prosodicamente o português europeu do brasileiro.Palavras-chave: prosódia; AMPER-Por; português europeu; português brasileiro; dialetologia.Abstract: This work aims to compare the prosody used in declarative and interrogative sentences in Brazilian Portuguese (spoken in the cities of Belém, Belo Horizonte, Florianópolis and São Paulo) and in European Portuguese – spoken in the cities of Vinhais (mainland), Fenais (Azores) and Calheta (Madeira Island). The acoustic parameters of fundamental frequency, duration and intensity were analyzed in 252 sentences which are part of the AMPER-Por corpus. The pre-nuclear, nuclear and final pitch were observed and this allowed to find some differences between Brazilian and European Portuguese, mainly that spoken on the islands. Regarding the duration, the main difference between Brazilian and European Portuguese is the longer duration in the Brazilian data. Intensity is not a relevant parameter to differentiate European Portuguese from Brazilian Portuguese.Keywords: prosody; AMPER-Por; European Portuguese; Brazilian Portuguese; Dialectology.

Received Pronunciation

Spoken Nigerian English (hereafter NigE) is said to differ significantly from Received Pronunciation (hereafter RP). Several studies (e.g. Adetugbo, 1977; 2004; Atoye, 1991; Udofot, 2004) conducted particularly from segmental and suprasegmental perspectives have established this. However, not so much has been done to verify this at the level of connected speech. Yet the features of connected speech contribute significantly to the marked difference between the native and non-native English accents and are capable of impairing intelligibility between speakers of both varieties (Allen, 1961: xiv; Laver, 1968: 156). Therefore, this study investigates two connected speech features (assimilation and elision) at morpheme and word boundaries, in order to provide explanations for how spoken educated NigE approximates to and deviates from RP.

Closest Conjunct Agreement

This paper provides a corpus-based study of agreement with post-nominal adjectives in coordinate nominal expressions with only one determiner in European Portuguese (EP). It aims to provide clues to understand the patterns of agreement that contradict the predictions of our previous studies in which we made a distinction between two constructions corresponding to the same categorial linear outputs: (a) those associated with the reference of only one entity and (b) those in which nouns are used to refer distinct entities. Since it was suggested by those previous studies the existence of parallel patterns of agreement between Spanish and EP in these types of constructions, we aim to provide a preliminary comparative study that allow us to explore this possibility, namely in what concerns the closest conjunct agreement in both gender and number (considering the different behaviors of the values of these features). Finally, we aim to evaluate the adequacy of some proposals presented for Spanish to explain the EP data, contributing to the description of these structures and presenting some clues for further investigation.

Task Conditions

Purpose Prior investigations suggest that simultaneous performance of more than 1 motor-oriented task may exacerbate speech motor deficits in individuals with Parkinson disease (PD). The purpose of the current investigation was to examine the extent to which performing a low-demand manual task affected the connected speech in individuals with and without PD. Method Individuals with PD and neurologically healthy controls performed speech tasks (reading and extemporaneous speech tasks) and an oscillatory manual task (a counterclockwise circle-drawing task) in isolation (single-task condition) and concurrently (dual-task condition). Results Relative to speech task performance, no changes in speech acoustics were observed for either group when the low-demand motor task was performed with the concurrent reading tasks. Speakers with PD exhibited a significant decrease in pause duration between the single-task (speech only) and dual-task conditions for the extemporaneous speech task, whereas control participants did not exhibit changes in any speech production variable between the single- and dual-task conditions. Conclusions Overall, there were little to no changes in speech production when a low-demand oscillatory motor task was performed with concurrent reading. For the extemporaneous task, however, individuals with PD exhibited significant changes when the speech and manual tasks were performed concurrently, a pattern that was not observed for control speakers.
