Investigation of non-pitch-accent Portuguese: no evidence fa
نویسنده
چکیده
The aim of this paper is twofold: (a) to investigate possible differences in durational patterns within phrase stress groups contrasting stress clash vs nonclash condition, and (b) to test the assumptions of a coupled-oscillator model of speech rhythm production. Measures of duration for relevant units in isolated read sentences uttered by four subjects were statistically analyzed and tonal events were annotated. The pattern that emerges from the analyses is that of a monotonous increasing of duration of syllablesized units when approaching phrasal stress. These results contradict the Rhythm Rule and seem to indicate that no apparent, systematic, duration-related stress shift seems to take place in Brazilian Portuguese.

Abstract: This research has been carried out in the framework of Auto segmental-metrical (AM) phonology to study the stress in Persian. Two types of abstract and concrete prominences were distinguished in which the first one refers to the stress and the second one refers to the pitch accent. Stress is assumed to be a lexical property of the lexemes, but pitch accent is assumed to be an intonati...
