Frequency characteristics of 583 Korean meaningful monosyllabic words were analyzed to improve understanding of speech recognition ability based on the hearing configuration. Twenty Korean young adults (10 males & 10 females) with normal hearing produced 583 words in context situations. Data were collected by using Computerized Speech Lab (CSL 4300B) and analyzed by using Praat 4.3.14. The analysis according to vowels and final consonants of the Korean meaningful monosyllabic words showed frequency differences depending on the initial consonants. Therefore, the words were analyzed based on the initial consonants. The mean frequency of intial consonants of /ᆨ/ was 1,560.17 Hz, /ᆩ/ was 1,957.07 Hz, /ᆫ/ was 241.09 Hz, /ᆮ/ was 4,154.06 Hz, /ㄸ/ was 4,263.33 Hz, /ᆯ/ was 288.22 Hz, /ᆷ/ was 245.04 Hz, /ᆸ/ was 1,402.02 Hz, /ㅃ/ was 1,409.95 Hz, /ᄉ/ was 4,965.60 Hz, /ᄊ/ was 5,937.91 Hz, /ᄋ/ was 1,406.87 Hz, /ᄌ/ was 4,617.41 Hz, /ᄍ/ was 4,998.60 Hz, /ᄎ/ was 4,584.13 Hz, /ᄏ/ was 1,351.06 Hz, /ᄐ/ was 4,202.87 Hz, /ᄑ/ was 1,363.12 Hz, and /ᄒ/ was 1,407.43 Hz. These results can be used clinically for better audiological assessment and rehabilitation. However, more data should be investigated systematically for appropriate clinical application in the future. KEY WORDS：Frequency analysis·Frequency characteristic·Korean meaningful monosyllabic words.
