The Phonetic Nature of the Phonological Contrast between the Lenis and Fortis Fricatives in Korean

The phonetic nature of the contrast between the lenis fricative /s/ and the fortis fricative /s*/ has been specified in various aspects but the vowels after the friction of the two fricatives have not been investigated. The present study provides detailed information about the characteristics of the vowels following friction. H1-H2 was measured in /CVda/ context across 8 Korean monophthongs. In non-high vowels, earlier portions of the vowels show a sharp contrast: a gradual decrease of the value of H1-H2 in the lenis fricative and a gradual increase of the value of H1-H2 in the fortis fricative. In high vowels, earlier portions of the vowels show a gradual decrease in H1-H2 in both fricatives. A higher order difference in H1-H2 between [shVda] and [s*Vda] was inversely proportional to vowel height in Korean.
