Specifically, we will analyze each participant's phonemic inventory in the initial and final position with respect to place and manner of production rather than phonemic target. We will also use relational analyses, from the point at which we obtain 90 different words. We will then compare the child's production with the standard adult phonemic target. Speech development will be assessed using the Percent Phoneme Correct and Percent Vowel Correct (PPC or PVC ) {Shriberg and Kwiatkowski, 1982). When developmentally appropriate, phoneme production skills will also be assessed using the Goldman-Fristoe Test o(Articulation-2 (Goldman & Fristoe, 2000). This measure has norms based on the performance of normal-hearing children from age 2 years to 21 years.
