The study of Portuguese fricatives is a complex problem, which has not been explored fully. As part of a larger study of the acoustic properties of Portuguese fricatives, corpora of Portuguese words containing /f, v, s, z, ʃ, ʒ/, nonsense words with Portuguese phonology, and sustained Portuguese fricatives have been recorded and analysed. Results show that more than half of the voiced fricatives devoice. Averaged power spectra were computed for all fricatives; differences between fricatives, in particular related to syllable stress, are described.
