Open-Set Monosyllabic Speech Perception Test for Preschool Children

Abstract

Background and Objectives：An open-set monosyllabic speech perception test is necessary, not only to devise habilitation programs but to select candidates and estimate performance in pediatric cochlear implant program. The purpose of this study is to develop a validated open-set monosyllabic speech perception test for preschool children. Subjects and Method：Qualitative test development was based on vocabulary familiarity, syllabic and phonemic frequency, and phonetic balancing between the lists. The devised test lists were applied to 138 normal hearing children and 46 children with cochlear implant to examine the validity and reliability. Results：The final two test lists were made up of 100 items with 260 phonemics. The consequential validity of this devised test was proven by the applied results that the speech perception score of children with implanted devices was significantly lower than that of normal children, when controlling for the length of auditory experience. Conclusion：The developed monosyllabic speech perception test is the validated instrument for preschool children. It is sensitive to perceptual characteristics of articulatory function in cochlear implanted children. The validity of this test needs to be enhanced by clinical application and further item analysis. (Korean J Otorhinolaryngol-Head Neck Surg 2009;52:312-21)
