A Helpful Way to Analyze Consonant Consistency in a Child

A helpful way to analyze consonant consistency in a child with suspected inconsistent speech disorder is to:

A) create a phonetic inventory of singleton consonants and consonant clusters.
B) create an inconsistency matrix with intended consonants on the horizontal axis, and the child's realizations of the intended consonants on the vertical axis.
C) identify the variety of phonological processes evident on each word, then calculate the average number of phonological processes per word.
D) determine the child's phonetic inventory constraints, positional constraints and sequence constraints.
