This paper describes the acoustic characteristics of sound [s] in the cities of: Medellín and Apartadó and explores the hypothesis that the articulation of /s/ will serve to distinguish between the dialects spoken in these two areas. The study analizes 943 [s] produced by a total amount of 32 speakers. The following parameters were considered in the analysis: Center of gravity, spectral peak, standard deviation of the spectrum, skewness, kurtosis, zero crossings and harmonic-noise ratio. Results suggest that: in syllable onset [s] is more apical in Medellín and more dentalised in Apartadó. Also, Medellín’s onset [s] is more sibilant. In coda position, there is no difference between the two dialects. [ABSTRACT FROM AUTHOR]

This paper contains the results of a set of perception tests that aimed at measuring perceived prosodic distances between different Romance languages (Italian, Friulian, Sardinian, Catalan, and Spanish). Data were collected within the framework of the AMPER project. The results were obtained by means of discrimination and identification tasks where the judges were 31 native speakers of Catalan form Barcelona and the stimuli were broad focus statements and yes-no questions in the above-mentioned languages. The perceived distances are then compared with the results of a dialectometric analysis of acoustic data. This comparison shows that the perceived distances are related to acoustic differences.
