Abstract

|
An Electropalatographic (EPG) study was conducted to investigate the articulatory characteristics which determine the distinction between the Korean lax fricative [s] and tense fricative [s´]. This study also intended to test if an increase in the degree of tensity (lax fricative [s] < tense fricative [s´]) induces a decrease in coarticulatory vocalic effects. The results indicated that the increase in the tensity of Korean fricatives is closely related to the increase in the narrowness of the groove width (wider contact at the place of articulation), the forward shifting in the place of articulation, and the longer duration of the constriction (longer maintenance in the manner of articulation). It was also found that coarticulatory vocalic effects on Korean fricatives are affected by Recasens´ two rules of constraint (1983) : spatial and temporal constraints.
