RESUMO

The aim of this essay is to analyze the way children deal with stress-clash in Brazilian Portuguese from the acoustic phonetic point of view. The analyzed parameters were the duration and fundamental frequency of vowels since these are the main acoustic parameters of primary stress in this language (cf. Moraes, 1987; Massini-Cagliari, 1992). In Brazilian Portuguese, adult language phonology and phonetics present different behavior in relation to stress class resolution. In phonological terms, following Nespor and Vogel (1986) for Italian and Selkirk (1984) for English, Abousalh (1997) and Santos (2002) claim that Brazilian Portuguese speakers use the strategy of stress shift in order to undo stress clash, and this strategy occurs inside the phonological phrase level. From a phonetic point of view, Barbosa (2002) has shown that stress shift occurs neither apparently nor systematically, in relation to the acoustic parameter of duration in Brazilian Portuguese, the main parameter for the duration of primary stress in this Brazilian Portuguese (cf. Moraes, 1987; Massini-Cagliari,1992). In this study, the child analyzed, my daughter, was recorded at age 5;7 in order to examine the possibility of stress shift and duration strategy in children. For the elaboration of the corpus, 12 target sentences were created. Six of them with stress clash and another six without the referred phenomenon. Care was taken so as to control the number of phrase pairs in such a way that same number of syllables of the sentences and rhythmic structure were maintained. The child repeated each sentence of stressclash X non stress-clash conditions 5 times, for a total of 60 acoustically analyzed sentences. According to the results of the statistical analyses, from the phonetic acoustic point of view the findings point to a trend of maintaining the stress-clash in the contexts of "clash" and this trend is one for the maintenance of the duration of the vowels in the control sentences contexts on the non stress-clashes in this corpus. That is, one can suggest, since the case under analyses, even with the stress-shift representing an optional strategy to undo the stress-clash in the PB, it is more tolerated than generally assumed (cf. Barbosa 2002 and Madureira 2002)
