Abstract: This article frstly unifes the phonetic concepts and phonetic symbols of Korean and Chinese, and then reviews the issues concerning the sound value, palatalization, voicing, etc. of these letters from the perspective of Chinese phonetic rhyme. It is argued that the sound value of the Chinese dental head sounds ᅎ, ᅔ, ᅏ, ᄼ, ᄽ is alveolar, the sound value of main dental sounds ᅐ, ᅕ, ᅑ, ᄾ, ᄿ is retroflex but becomes alveolo-palatal when combined with the semi-vowel j, the sound value of Korean dentals ㅈ, ㅊ, ㅉ, ㅅ, ㅆ is postalveolar, and the sound value of semi-dental ㅿ is postalveolar /Z/. The conclusion thus drawn is different from those of the most previous studies of alveolar. In the research methodology, this article adopts an original approach assuming a pair of semi-dental sounds: the semi-dental head sound and the semi-main dental sound in order to speculate the position of the semi-dental sound. The article also proposes the concept of semipalatalization to explain the different stages of the Korean palatalization process.
