Abstract

Background and Objectives: Various speech perception tests have been developed for children with hearing loss (HL) in Korea, although they are not standardized yet. This study aims to examine the actual condition of speech perception tests for children with HL in Korea.
Subjects and Method: Survey questionnaires and speech perception tests for children with HL were collected from 24 cochlear implant (CI) centers between March and July 2009. The speech perception tests were classified according to target ages, speech stimulus levels, and response formats. We interviewed speech therapists who had developed monosyllabic word (MW) tests, and gathered source materials, considerations, and limitations of the MW tests. We also analyzed vocabulary familiarity and phonetic balancing of words in the most commonly used MW tests.
Results: Thirty-eight kinds of speech perception tests for children with HL were collected from 24 CI centers. Among these tests, open-set MW tests and sentence tests were used in all centers. Speech therapists responsible for developing MW tests had selected words from textbooks, storybooks, and spontaneous speech data to secure vocabulary familiarity and phonetic balancing within each list. Four commonly used MW tests revealed that vocabulary familiarity was compatible with commonly used MW in preschoolers and demonstrated a similar trend in phoneme frequencies.
Conclusion: The results of this study showed that current speech perception tests for children with HL should be verified, revised, and standardized in an experimental setting.
