Development of Korean Consonant Perception Test

Abstract

The purpose of this study was to develop Korean Consonant Perception Test (KCPT), that is a phonemic level including elementary data to evaluate speech and consonant perception ability of the normal and the hearing impaired qualitatively and quantitatively. KCPT was completed with meaningful monosyllabic words out of possible all Korean monosyllabic words, considering articulation characteristics, the degree of difficulty, and the frequency of the phonemic appearance, after assembling a tentative initial and final consonants testing items using four multiple-choice method which were applied to the seven final consonant regulation and controlled with the familiarity of the target words.Conclusively, the final three hundred items were developed including two-and one-hundred items for initial and final testing items, respectively, with the evaluation of the 20 normal hearing adults. Through this process, the final KCPT was composed upon the colloquial frequency following identification of no speakers' variances statistically and elimination of the highly difficult items. The 30 hearing impaired were tested with KCPT and found that the half lists, A and B, were not different statistically and the initial and final testing items were appropriate for evaluating initial and final consonants, respectively.

Effect of Hearing Rehabilitation Therapy Program in Hearing Aid Users: A Prospective Randomized Controlled Study

“…PTA without HAs and sound field threshold audiometry testing with HAs were conducted to exclude changes in hearing level and inappropriate function of HAs. Audiological outcomes were evaluated with word recognition score (WRS), Korean consonant perception test (KCPT) [ 15 ], and Korean speech perception in noise (KSPIN) test [ 16 ]. Subjective benefits were measured by two validated questionnaires: the Korean Version of the Hearing Handicap Inventory (KHHIE) and the International Outcome Inventory for Hearing Aids (K-IOI-HA) [ 17 , 18 ].…”
