  • The purpose of this paper is to review the contribution made by some phoneticians including Si-gyung Chu, Du-bong Kim, Hyun-bae Choi, and Geuk-ro Lee in the early 20th century. It is known that the period can be characterized as the coexistence of traditional phonetics and modem phonetics. Si-gyung Chu well recognized the physical nature of speech sounds from the physiological point of view. Although Du-bong Kim adapted Chu's approach in some ways, he made some more detailed modifications in explaining the vocal organs. Hyun-bae Choi tried to explain the consonants and vowels systematically based on Western theories of phonetics. Finally, Geuk-ro Lee made the most significant contribution by introducing the experimental phonetics.
