Abstract

Achieving voicing during fricatives is complex because voicing and frication require opposite production strategies that must be managed effectively at the supralaryngeal level. Previous research has suggested that there are differences in tongue-to-palate contact patterns that are conditioned by voicing. However, findings have been restricted to a single time point and have been generally inconclusive. This study used electropalatography (EPG) to investigate differences in the dynamics of contact in voiced and voiceless lingual fricatives. Participants were six typically speaking Croatian adults. The speech material consisted of symmetrical VCV sequences, where C was /s z ʃ ʒ/. EPG measures were taken throughout the fricatives and indices were used to quantify place of articulation (CoG), groove width and target configuration onset. The EPG measures showed similar results for voiced and voiceless fricatives during their central portions. However, there were notable differences at the periphery of the fricative period, the most significant being that the voiceless fricatives reached a stable period in terms of tongue placement and groove configuration later than the voiced fricatives. The results support aerodynamic evidence that voiced and voiceless fricatives differ in the onset and the offset of turbulence.
