Análise acústica dos correlatos prosódicos do acento lexical do português brasileiro
The current work revisits the prosodic characteristics of the Brazilian Portuguese (PB) lexical stress, matching an acoustic approach and sociolinguistic corpus. We analyze here speech samples of 6 native speakers of PB, from Pará, stratified into sex and having a high educational level. The corpus...

| description | The current work revisits the prosodic characteristics of the Brazilian Portuguese (PB) lexical stress, matching an acoustic approach and sociolinguistic corpus. We analyze here speech samples of 6 native speakers of PB, from Pará, stratified into sex and having a high educational level. The corpus is formed of three random repeats of 21 words, being 7 by lexical stress, inserted in a vehicle phrase (Eu digo _____ devagar). As the 3 syllables of each word were analyzed, the final corpus is composed of 1134 tokens (3 kinds of lexical stress x 7 words x 3 syllables x 3 repetitions x 6 speakers). In order to validate the hypothesis, the mean fundamental frequency (F0) was calculated in semitone and the intensity (dB) taken in the nuclear element of each syllable. Duration (ms) was measured considering the whole syllable. The data demonstrate that duration is the most robust physical parameter in the distinction between stressed and unstressed syllables. The pre-tonic syllables, in the case of the paroxytones and oxytones, register the greatest number of F0 variations. The intensity was not a robust parameter in the characterization of lexical stress in BP. |
