Phonetic and phonological analyses
A total of 228 errors were produced by participants (M¼3.30, SD¼12.26). In the group as a whole,
24 different error types were identified.
Of these 24 different error types, only 12 were evident at least three times in the speech of one or more children.
Figure 1 shows the frequency of the 12 different error types; Figure 2 shows the number of children producing each error type at least three times.
In both figures developmental processes are marked with white bars and disordered processes/errors are
marked with black bars.
