Abstract

|
Acoustic and aerodynamic characteristics of Cheju consonants were examined with the focus on the wll-known three-way distinction among stops (i.e., lenis, fortis, aspirated) and the two-way distinction between s and s^*. Acoustic parameters examined for the stops included VOT, relative stop burst energy, Fo at the vowel onset, H1-H2, and H1-H2 at the vowel onset. For the fricatives s and s^*, acoustic parameters were fricative duration, Fo, centroid of the fricative noise, RMS energy of the frication, H1-H2, and H1-H2 at the onset of the following vowel. In investigating aerodynamics, intraoral pressure and oral flow were included for the bilabial stops. Results indicate that, although Cheju and Korean are not mutually intelligible, acoustic and aerodynamic properties of Cheju consonants are very similar in every respect to those of the standard Korean. Among other findings there are three crucial points worth recapitulating. First, stops are systematically differentiated by the voice quality of the following vowel. Second, stops are also differentiated by aerodynamic mechanisms. The aspirated and fortis stops are similar in supralaryngeal articulation, but employ a different relation between intraoral pressure and flow. Finally, our study suggest that the fricative s is better categorized as ´lenis´ than as ´aspirated´ in terms of its phonetic realization.
