An Acoustical Study on the Syllable Structures of Korean Numeric Sounds

국어 숫자음의 음절구조에 대한 음향적 분석

The purpose of this study was to examine the syllable structures of ten Korean numeric sounds produced by ten subjects of the same age. Each sound was normalized and divided into onset, vowel, and coda sections. Then, acoustical measurements of each syllable were done to compare the ten sounds. Results showed that there was not much deviation from the grand average duration and intensity for the majority of the sounds except the two diphthongal sounds on which their boundary points varied among the speakers. Some syllable boundaries were quite obvious while others were ambiguous. There seemed some tradeoff among the syllable components depending on their acoustic features.
