Análise acústica das sílabas tônicas em Apurinã (Aruák)

Abstract

This paper investigates the acoustic correlates of the prominent syllable, henceforth accent mark in the apurinã language, taking in consideration the hypotheses of Facundes (2000) and Brandão ( 2010). The research investigates possible acoustic correlates of the stress such as F0, intensity and duration of the vowels in stressed syllables with secondary stress and unstressed syllables to verify, from statistical analysis, which one is the most important correlate associated with stress in the language. This paper is divides into three parts: 1) the introduction, where the people, language aspects, the methodology and the theorists used in the analysis are presented; 2) a brief approach about the stress described by Facundes and the application of the metrical stress theory proposed by Hayes (1995) explained; and in 3) is the acoustic analysis in itself and the result of the statistical tests as well as a brief conclusion and list of the words used in the research.
