Lucy’s:
(i) Articulation is age appropriate .
There is therefore no need to do the Articulation Subtest.
(ii) Inconsistency score (25%), below the criterion of 50%. There is therefore no need to
do the Inconsistency Subtest.
(iii) There is no need to do the Oromotor Subtest #

Childhood Apraxia of Speech Inconsistent Phonological Disorder
Inconsistent errors Inconsistent errors
Increasing errors with increasing length Increasing errors with increasing length
Poor sequencing of sounds (eg. metathesis);
marked syllable segregation.
Wrong choice of phoneme rather than order
errors; no syllable segregation.
Poor oro-motor skills Oro-motor skills within normal limits
Groping; silent posturing No groping, no silent posturing
Prolongations and repetitions of speech
sounds
No prolongations and no repetitions of
speech sounds
Poorer in imitation than spontaneous
production
Better in imitation than spontaneous
production
Dysfluent, short utterance length,
prosodic disturbance, slow speech rate
Fluent, normal utterance length, normal
affect, normal-rapid speech rate
Best therapy focuses on phonetic gesture Best therapy focuses on word production
