Estudo comparativo da variação das vogais médias pretônicas em falares mineiros

Abstract

In Zagari (1998), Machacalis is Baiano speaking area, while Piranga and Ouro Branco are Mineiro area. Nascentes (1953) proposed Machacalis as Baiano speaking area, Piranga as Fluminense area and Ouro Branco as Mineiro area.The productions of pretonic vowels is relevant to the various divisions of Brazilian speech. Thus, this work studies the variation of the pretonic vowels in Minas Gerais' towns of Piranga, Ouro Branco and Machacalis. This research goals are: to describe the pretonic vowels contributing to a description of Minas Gerais and the Brazilian Portuguese speaking varieties; to study the phonological processes envolved to determine the triggers of these processes and to discuss the proposed division of Minas Gerais local dialects. The theoretical-methodological model of Linguistic Variation and Change (Labov, 1972) and the Autossegmental Phonology (Goldsmith, 1976) and Feature Geometry (Clements and Hume, 1996) models were adopted. For statistical analysis, the logistic regression model presented in SPSS software was used. We have investigated the social and internal factors envolved. This work addresses the following questions: What are the exact roles of the following vowels? What is the exact role of adjacent consonant? Is there lexical diffusion? Is there any performance of secondary stress? Are differences in the phonological process in the three cities? Is there evidence of progression in any of these processes? What is the role of social factors? Which are differences between the dialects in question?
