Stochastic restrictions in intrasyllabic phoneme strings based on a surface level and a proposal for an emerging model

초록

This corpus-based study aims to demonstrate that structural restrictions in intrasyllabic phoneme strings are not categorical but stochastic. To achieve this goal, an attempt was made to quantify the cohesion strength between sub-syllabic phonemes by measuring the correlation coefficient, gamma-phi. The sources were collected from ‘Moduui Corpus’ provided by the National Institute of Korean Language. A total of 4,202 noun words were extracted, and 7186 C1VC2 syllables were analyzed. The findings indicate that, in the surface forms, the mean values of gamma-phi for C1Vs are statistically greater than those for VC2s across twelve sub-corpora. However, in specific syllables, some VC2s exhibit greater cohesion strength than C1Vs. This study concludes that cohesion between sub-syllabic roles is sequence-specific and suggests that the sub- syllabic constituency represents the emergence of phoneme sequences with relatively greater cohesion strength based on the surface forms, not primitive structures. Finally, an emerging model is proposed as an alternative representation of Korean syllables. The current study achieves the quantification of structural restrictions in Korean syllables and contributes to addressing the limitations of traditional syllable models by exploring the intrasyllabic system through empirical data.
