Estudo acústico das consoantes líquidas do Português Europeu: evidências temporais e espectrais

In this paper, we present data resulting from a temporal and spectral analysis of European Portuguese liquid consonants (/l, ʎ, ɾ, ʀ/) produced in onset position by twonative speakers. The results obtained for the alveolar lateral indicate a velarized /l/ in onset position, as other studies for European Portuguese had already showed. It was also observed that /ɾ/ is a liquid with highest values of F1 frequency and is the consonantwith the shortest duration. The highest frequency of F2 was obtained for the palatal lateral. In this study, the values of F3 and F4 frequency suggest no major differences between liquid consonants. There was some inter-speaker variability.
