Phonetic studies of the Korean prevocalic glides have often suggested that they are shorter in duration than those of languages like English, and lack a prolonged steady state. In addition, the formant frequencies of the Korean labiovelar glide are reported to be greatly influenced by the following vowel. In this study the Korean prevocalic palatal glide is investigated vis-à-vis the two phonologically similar configurations of another language - the glide /j/ and the secondary palatalization of Russian, with regard to the inherent duration of the glide component, F2 trajectory, vowel-to-glide coarticulation and glide-to-vowel coarticulation. It is revealed that the Korean palatal glide is closer to the Russian palatalization in duration and F2 trajectory, indicating a lack of steady state, and to the Russian segmental glide in the vowel-to-glide coarticulation degree. When the glide-to-vowel coarticulation is considered, the Korean palatal glide is distinguished from both Russian categories. The results suggest that both the Korean palatal glide and the Russian palatalization involve significant articulatory overlap, the former with the vowel and the latter with the consonant. Phonological implications of such a difference in coarticulation pattern are discussed, as well as the comparison between the Korean labiovelar and palatal glides.
对韩语元音前滑音的语音学研究常常表明，它们的时长比英语等语言的滑音短，且缺乏延长的稳态。此外，据报道，韩语唇软腭滑音的共振峰频率受后续元音的影响很大。在本研究中，针对滑音成分的固有时长、F2轨迹、元音到滑音的协同发音以及滑音到元音的协同发音，将韩语元音前腭滑音与另一种语言在语音上相似的两种构型——滑音/j/和俄语的二级腭化——进行了对比研究。结果表明，韩语腭滑音在时长和F2轨迹上更接近俄语腭化，这表明其缺乏稳态，在元音到滑音的协同发音程度上更接近俄语的音段滑音。当考虑滑音到元音的协同发音时，韩语腭滑音与俄语的这两类都有所不同。结果表明，韩语腭滑音和俄语腭化都涉及显著的发音重叠，前者与元音重叠，后者与辅音重叠。本文讨论了这种协同发音模式差异的语音学意义，以及韩语唇软腭滑音和腭滑音之间的比较。
