Secondary stress, intensity and fundamental frequency in Brazilian Portuguese

This paper investigates whether values of acoustical correlates of pretonic syllables adjacent to the one(s) perceived as bearing secondary stress could predict such perception in Brazilian Portuguese (BP) data. In order to pursue this goal, a comparison is made between pretonic syllables perceived as bearing secondary stress and those perceived as not bearing it. According to the results, obtained by application of statistical analyses, it is possible to claim that variation in intensity and in F0 in syllables perceived as bearing secondary stress, as well as in adjacent syllables, can be taken as a robust correlate for data perception regarding secondary stress placement in BP. Variation in intensity and in F0 in syllables perceived as bearing secondary stress and variation in intensity and in F0 in the other adjacent pretonic syllables seem to be complementary information for the perception of secondary stresses by BP speakers. The results point to relevant questions for further work concerning the rhythmic and intonational organization of Brazilian Portuguese.info:eu-repo/semantics/publishedVersio

Distinguishing emphatic and Prosodic Word initial stresses: evidence from Brazilian Portuguese

In European Portuguese (EP), emphatic stress and initial stress have been reported to be optionally assigned to the first (or in some cases the second) syllable of a Prosodic Word (PW) ([1]). In Brazilian Portuguese (BP), initial stress (and/or H-tone) has been claimed to be assigned with reference to the primary stress position and be dependent on the number of pretonic syllables within a PW ([2]). [3], [4] and [5] suggest that in BP secondary stress assignment essentially signals the beginning of the PW in emphatic contexts, however. Although [5] reports that in emphatic contexts the initial stress and the ‘H-tone’ can coincide with a secondary stress, the nature of this type of stress and the difference between emphatic stress and PW initial stress in BP is in general not discussed. In this paper we argue that, although the two types of stresses in BP are tonally signaled, they are distinct, both in function and in distribution. Empirical data from two varieties of Portuguese spoken in Brazil (Paraná and Minas Gerais states) are presented, showing that the emphatic stress has a wider distribution than the initial stress, in neutral contexts. The emphatic stress may occur in any syllable from the stressed syllable leftwards, within the PW, including the syllable immediately adjacent to word-stress. The initial stress, by contrast, is found on the first or second pretonic syllable of PW, and there is a minimal distance of two syllables between initial stress and word-stress (e.g. governaDOres ‘governors’) ([2]). We argue that the initial stress is an edge phenomenon, marking PW initial positions, unlike the emphatic stress. In both cases, the tonal association is evidence for the PW domain in BP, because neither type of stress exceeds the limits of this domain (i.e. none of them can appear in post-tonic syllables of non-final PW).info:eu-repo/semantics/publishedVersio
