Severe Speech Disorder Project

Auditory processing: comparing phonologically disordered and typically developing children

Project Description

The purpose of the proposed research is to investigate auditory processing of non-speech and speech sounds for children with phonological disorders and children who are developing typically. The major objective of this research is to document auditory processing capacities of children with phonological disorders and typical development and to examine whether the deficit in auditory processing is an etiological factor correlated with phonological disorders. The outcome of this study may provide clinicians with knowledge regarding the importance of considering auditory abilities of children with phonological disorders. The long-term goal of this study is to incorporate relationships between auditory perception and speech production capacities for children with phonological disorders across phonological treatment, to develop a clinical testing battery of auditory processing for children with phonological disorders, and to examine how speech (phonemic) perception training can improve the efficiency of phonological treatment.

Description of Studies

Basic auditory processing capacities of frequency selectivity and temporal processing will be measured as well as speech perception and production for two groups of children age 5-6 years. Groups are characterized as children who are developing speech within typical chronological age expectations and children who are diagnosed with severe speech disorders
