Acoustic and Perceptual Characteristic of Italian Stop Consonants

We report the results of a study carried out to analyse the acoustic and perceptual characteristics of Italian stop consonants. The aim of this study is twofold: give an acoustical description of Italian stops and investigate which are the perceptual cues relative to their place of articulation. From the acoustic point of view we report: the measurements relative to the length of the whole consonant and of its release burst; the F1 and F2 of the following vowel measured at the beginning of it. Moreover we counted the presence of the release burst and we tried to describe its acoustical characteristics in terms of the spectral structure. From the perceptual point of view we report the results of three perceptual tests that we run with the aim of evaluating whether the release burst or the formant transitions are more relevant for the perception of Italian stop consonants' place of articulation.
