An Electropalatographic Study of Alveolar and Palatal Consonants in Catalan and Italian

Abstract

Electropalatographic data for Catalan and Italian reported in this paper reveal the existence of two categories of palatal consonants, namely, alveolopalatals ([n], [λ]) and palatals proper ([j]). All these consonants are produced with a single place of articulation and thus are not good candidates for complex segments involving a tongue front articulator and a tongue dorsum articulator. A higher degree of coupling between the primary articulator and other tongue regions for alveolopalatals and palatals than for alveolar [n] accounts for a reduced sensitivity to coarticulatory effects for the former vs. the latter. Alveolarpalatal correlations reported in this study support the notion of relative independence between different tongue articulators for non-dorsal vs. dorsal consonants. Differences in articulation and coarticulation were found for Italian vs. Catalan. In comparison with their Catalan counterparts, Italian shows the following properties: Consonants are more anterior, [n] allows less coarticulation at the alveolar zone (in line with the laminal nature of the consonant), and long alveolopalatals exhibit more contact and less coarticulation at the front palatal zone.
