Phonological studies on Brazilian Portuguese (BP) consider that besides the main lexical stress, there is a secondary stress (SS), which would fall on each even prestressed syllable, counted from right to left, starting from the primary stressed one, characterizing a strong/week alternation (trochaic feet). Based on perceptual tests with read speech material, it was showed that a SS was perceived regularly in words with more than one prestressed syllable, but its location admits variation, with two basic patterns: either the SS following the binary alternation rule, or the SS falling on the initial syllable, potentially creating a ternary foot. Acoustical analysis showed that there is no stable correlate of SS: it can be either fundamental frequency, or a combination of duration and loudness.
