Free play and elicited language samples were obtained monthly for 10 to 12 months from five late talking children. Analysis indicated that three of the children resolved their late onset of speech by 33 to 35 months of age. Both quantitative factors (e.g., limited phonetic inventory) and qualitative factors (e.g., atypical error patterns) were…

This study used survival analysis to overcome problems of principled generalization and individual variability in analysis of the conversational speech of 24 children with speech delay recorded over two years. The derived normalization probabilities were lagged according to the strong delay hypothesis and results converged with previous normative…

Probable ages of normalization were calculated for 24 children with speech delay, using Kaplan-Meier analysis. Formulas are provided that permit calculation of the likelihood that individual children will normalize by a given age. Analysis revealed two different paths to normalization with children following one of the paths likely to retain…
