Electroglottographic-Phonetic Study on Korean Phonation Induced by Tripartite Plosives in Yanbian Korean

Yinghao Li, Jinghua Zhang


This paper examined the phonatory features induced by the tripartite plosives in Yanbian Korean, broadly considered as Hamkyungbukdo Korean dialect. Electroglottographic (EGG) and acoustic analysis was applied for five elderly Korean speakers. The results show that fortis-induced phonation is characterized with more constricted glottis, slower spectral tilt, and higher sub-harmonic-harmonic ratio. Lenis-induced phonation is shown to be breathier with smaller Contact Quotient and faster spectral tilt. Most articulatory and acoustic measures for the aspirated are shown to be patterned with the lenis; However, sporadic difference between the two indicates that the lenis induces more breathier phonation. The diplophonia phonation is argued to be a salient feature for the fortis-head syllables in Yanbian Korean. The vocal fold medial compression and adductive tension mechanisms are tentatively argued to be responsible for the production of the fortis. At last, gender difference is shown to be salient in the fortis-induced phonation.
