Children with Inconsistent Phonological Disorder produce difficult words differently each time they attempt the word. This pattern suggests a problem with which underlying speech process?

• A. Phonological processing
• B. Phonological planning
• C. Motor planning
• D. Speech perception

Answer: (B)

This pattern points to a problem at the level of phonological planning—the stage where the intended sequence of sounds for a word is organized before any articulation takes place. When phonological planning is unstable, a child may generate different phoneme strings for the same target word on different attempts, leading to inconsistent pronunciations even though their articulatory muscles can move in a typical way. The issue isn’t primarily about moving the lips and tongue (motor planning) or about understanding or processing sounds (speech perception or broader phonological processing); it’s about how stable and organized the planned phoneme sequence is before actual speech.
