Resumo: In this paper, we investigated the spectral characteristics of labiodental, alveolar and postalveolar fricatives of the Brazilian Portuguese in terms of place of articulation and vowel context. We measured the spectral characteristic of fricative noise using the analysis of four spectral moments (center of gravity, standard deviation, skewness and kurtosis). Our results indicated a significant effect of place of articulation and vowel context on values of spectral moments for fricatives of Brazilian Portuguese. The results show that the fricatives were well differentiated by the center of gravity and standard deviation more than the other spectral moments, skewness and kurtosis.

A mensuração do espectro de frequência das fricativas foi realizada por meio da análise dos quatro momentos espectrais (centroide, variância, assimetria e curtose). Nossos resultados indicam um efeito significativo do ponto de articulação e contexto vocálico nos valores dos quatro momentos espectrais das fricativas do Português Brasileiro. Os resultados indicam que os momentos espectrais centroide e variância foram mais eficazes para diferenciar as fricativas do que os outros dois momentos, assimetria e curtose. Universidade Estadual De Maringá2015-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciLangCult/article/view/2514910.4025/actascilangcult.v37i4.25149Acta Scientiarum.
