ABSTRACT INFORMATION
Title: 'Development of a pediatric vowel discrimination task' Track: 2 - Audiological Services Keyword(s): Learning Objectives: Abstract: Intelligibility of connected discourse strongly relies on vowel information for adult listeners (Fogerty & Humes, 2012). To better understand the importance of vowels in young children, an easy to administer, pediatric vowel discrimination task is needed. Closed-set, picture pointing paradigms such as the Word Intelligibility by Picture Identification (WIPI; Ross & Lerman, 1970) are effective for pediatric word discrimination tasks (ASHA, 2012). Most WIPI word sets share a vowel but vary in the initial and/or final consonant, such that discrimination relies on consonant information. The goal of the current project was to develop a companion test to the WIPI that relied on vowel information. The task includes monosyllabic words arranged in sets of three. The words within each set vary only by the central vowel and are within the lexicon of a typically developing young child. Words are separated into three lists that are balanced for vowel articulation (i.e., position of tongue and degree of lip rounding) and word frequency. Preschool children easily identified the images and audio recordings that were created to depict the words. Perceptual data on the recognition of the word sets in noise for normal-hearing children will be presented. A successful vowel discrimination task will enhance studies of speech discrimination and auditory development in children. Future directions include a vowel discrimination tool to be used in clinic, enabling vowel discrimination testing of young children with hearing impairment. Better understanding pediatric auditory development will improve diagnoses as well as early intervention strategies. Session participants will identify the inherent constraints of developing a pediatric speech perception test. Participants will be able to describe the process used to develop a successful pediatric vowel discrimination task.
