Realizações dos fonemas /t/ e /d/ em Aracaju Sergipe.

Abstract

This dissertation registers the contours and the results of a research concerning the variation of [t]and [t], [d] and [d] in the Aracajuano s speech who have never been out of their town, Aracaju, for more than 2 years long, and whose parents were also born in Aracaju. The research was developed underneath the basis of the Theory of Linguistic Variation. 3, 679 occurrences of those variants in the speech of 36 aracajuanos distributed considering age, sex and familiar incomes were recorded with the resources of an mp3-recorder. In order to clear phonetic and phonological aspects of those realizations, The Autossegmental Phonology and the representational model of Geometry of Feature were also evoked. The data were analyzed with the instrumental resources of analysis of Quantitative Sociolinguistic. Varbrul (Pintzuk, 1988) programs were used in the analysis. Phonological context, Age and familiar income were the most relevant factors. The results pointed out simple realizations [t] e [d] as the variants that best represent aracajuano s speech, with a single constraint: in the ambience with a [j] in the precedent phonological context and with a [i] in the phonological following context, complex variants are used as the rule. Nevertheless, those results have indicated that complex variants may represent conservation or innovation depending on the phonological context it s used. Some linguistic change is predictable.
