The error word responses made by hard of hearing subjects on the articulation test for the Korean speech are studied. The structural analyses of word responses are as follows : 1) In the initial consonants, outstanding confusions are ""ㄱ""""ㄷ""(g, d) for ""ㅈ""(z), ""ㄷ""""ㄱ""(d, g) for ""ㅂ""(b) ""ㅂ""(d) for ""ㄷ""(d), ""ㄴ""(n) for ""ㅁ""(m) and ""ㅁ""(m) for ""ㄴ""(n). 2) It is interesting to observe that there is a greater percentage of error on ""ㅆ"(tN), ""ㅅ""(s), ""ㅎ""(h), ""ㅌ""(t), ""ㅋ""(k) in the perceptives, while a less percentage of error on these initial consonants by the conductives. 3) When vowel ""ㅓ"(@) is given in the stimulus, ""ㅗ""(o) is most frequently confused, and in order of ""ㅗ""(o) for ""ㅜ""(u) and ""ㅓ"(@) for ""ㅗ""(o). 4) There is relatively a less percentage of error on vowel ""ㅏ""(a), ""ㅣ""(i), ""ㅐ"(Å) and ""ㅕ"(i@) in every type of hearing loss. 5) In the final consonants, outstanding confusions are ""ㅅ""""ㄱ""(s, g) for ""ㅂ""(b), ""ㄴ""""ㅇ""(n, K) for ""ㅁ""(m) and ""ㅇ""""ㅁ"(K, m) for ""ㄴ""(n). 6) The final consonants ""ㅁ""(m), ""ㅂ""(b), ""ㄴ""(n) show relatively a greater percentage of error in every type of hearing loss. 7) Sound confusions occur more frequently in the articulation test than do omissions and insertions. 8) The nonconductives show more confusions for vowels and consonants than do the conductives. 9) Sound omissions occur more frequently by the nonconductives than do by the conductives. 10) Sound insertions occur more frequently in the initial position than in the final position regardless of the types of hearing loss.
