Clivagem e construções similares: contraste, foco e ênfase

This paper deals with so called cleft constructions and other similar structures in eight Portuguese varieties, aiming to show that the formal differences correspond to different functional strategies used by the Speaker to achieve his/her communicative intentions, i.e., Focus, Contrast and Emphasis, in accordance with the theory of Functional Discourse Grammar (Hengeveld and Mackenzie, 2008). This study takes as evidence real spoken occurrences extracted from a corpus organized by Linguistic Centre at the University of Lisbon, in partnership with the University of Toulousse Mirail and the University of Provence-Aix-Marseille. The results show the following distribution: cleft construction is a strategy for pragmatic function Contrast marking; Focus-ser constructions are used to highlight a constituent and (é) que is used as an operator of emphasis showing the speaker’s desire to intensify certain pieces of information.

Estabelecimento do contraste entre as fricativas por crianças com transtorno fonológico: manipulação de pistas acústicas

The present study focuses on the presence of covert contrasts in the speech of children with a phonological disorder. The hypothesis is that children with phonological disorders manipulate secondary acoustic cues in an attempt to distinguish the phonological contrasts. We used five audio recordings of the speech of five children with speech disorders, between four and five years of age, who showed the so-called “phonic substitution” involving the sound group of the fricatives. The data were edited and analyzed using the software PRAAT. A phonetic transcription of the first repetition of each child was performed by three evaluators, reaching a 66% agreement level. After the transcription, we carried out a contrastive phonological analysis of the production of the five children and, finally, an acoustic analysis of all the “substitutions”, based on six parameters. We discovered the existence of covert contrasts in the productions auditorily regarded as homophones by the evaluators, representing a total of 54% of total substitutions identified through an impressionistic approach by the evaluators. Children with phonological disorders are seen to rely on secondary acoustic cues in an attempt to distinguish fricative phonemes. The data obtained in this study allow us to reflect on the importance of considering the phonetic detail within the phonological models.
