Number of initial consonants in the phonetic inventories of the children with and without CLP across age determined from the PEEPS. The number of correct initial consonants used on the PEEPS for children with CLP (circles) and NC children (squares) across the ages of 18 to 36 months. The linear (CLP: dotted line) and curvilinear (NC: solid line) polynomials and means (filled symbols) are displayed for the groups.
