The confusion test with speech sounds is needed for reasonable word lists to obtain more exact results in speech tests. However, in Korean, confusion patterns among the speech sounds have not yet been studied.
The confusion test was given with 498 monosyllable sounds, which were frequently uged in normal conversation, to 80 normal listeners.
Thus, articulation scores and confusion patterns of Korean speech sounds for each tested monosyllable were obtained(table 1).
Confusion patterns are as follows:
1. Confusion was occurred among initial consonants, vowels and final consonants, respectively according to their distinctive features.
2. Over-all error response in tested words was 19.87%0. Final consonants were the most significant of error responses.
3. The initial nasal consonants and the liquid consonants in the final position were very rarely confused.
4. Vowels were more frequently confused in open syllable sounds than in closed ones.
5. Only in the final consonants were omissions and insertions of ´consonants observed. Omitted or inserted consonants were usually the simple, plosive ones.
