Miyeon Ahn. 2015. Acoustic properties of Korean fricatives and post-fricative vowels. Studies in Phonetics, Phonology and Morphology. 21.2. 245-256.
This study aims at examining the acoustical properties of the Korean fricatives /s/ and /s* / and post-fricative vowels. We examined both temporal and spectral properties in terms of the duration of friction, center of gravity (CoG) of /s/ and /s* / and the duration of periodic pulses, vowel qualities (F1, F2 and mean of F2 and F3), and the fundamental frequency (f0) of the immediate vowels. The results showed that /s* / was systematically longer and has a higher CoG than /s/ in all vowel contexts. Also, posttense vowels were significantly longer than post-lax ones while f0 and vowel qualities were contrastive in limited contexts. (Seoul National University)
