SHTEGORET E SHQIPES, PARAQITJE DHE ANALIZË AKUSTIKE E TYRE
The Glottal Sounds of Albanian, Presentation and Acoustic Analysis

Summary/Abstract: This study constitutes an analysis of acoustic cues for classification of place of articulation in fricatives. To date, no single metric has been found to classify fricative place of articulation with a high degree of accuracy. Different measurements were taken: duration, differences between the voiced and voiceless fricatives and overall spectral shape. Fricatives are produced by articulations that direst air flow through constrictions and/or onto obstacles causing turbulence. Turbulence provides a random, noise-like signal with a fairly flat spectrum in the normal range of speech frequencies. This noise is then shaped by cavity resonances adjoining the point of constriction. As we found there is an important relation between the place of articulation of the fricatives and their extension in the values of frequency: higher for anterior fricatives and lower for the posterior ones.
