RELAÇÕES DE COOCORRÊNCIA CV NA AQUISIÇÃO DO PORTUGUÊS BRASILEIRO: UMA DISCUSSÃO ACERCA DO PAPEL DAS CLASSES CONSONANTAIS

Abstract

The phenomenon of CV co-occurrence is characterized by the prevalent combination of some consonants and some vowels during the period of babbling along with the first words. Two main perspectives based on a dynamic origin have been evoked to explain the issue. The first one is called the Frame-then-Content theory (MACNEILAGE, 1998), which predicts that biomechanical inertia is the sensorimotor base of the syllable, the frame, preceding the phonic content. Under such view, the non-communicative movements would be the frame to the emergence of linguistic content phonic and the relationship between the movement and its acoustic effects would have privileged the speech, in the phylogenesis, as the main way to communication. The second perspective (ALBANO, 2009 a, b; 2011) states that the phonic factors in charge of forming the CV co-occurrence interact with individual differences and environmental conditions towards the child s linguistic production. In this work, we aim at (1) investigating the role played by the consonantal class of the sonorants and obstruents in the formation of CV coordination relations during the acquisition of BP. From this main goal, we have carried out a research on patterns of CV co-occurrence in longitudinal data of BP acquisition by 10 children, whose age was between 1:0 and 3:0 in the LIDES database, located in four age groups. We have also investigated the phenomenon in three stressing conditions unstressed initial syllable, stressed initial syllable and unstressed final syllable in an age group varying from 1:5 up to 2:5. Results show that child development seems to depend on the dynamics and motility in general. Such fact is evidenced by the changes regarding place of stressing and frequency of types and occurrences. This finding suggests that linguistic aspects, possibly determined be the grammar of the language, come into action more significantly in these positions, opposed to the claims of the Frame-and-Content theory. With respect to the role of the consonantal classes, we have found that the formation of the CV co-occurrences is strongly determined by the infant lexicon, which has been proved by the frequency of types and occurrences
