Which statement describes the two proposed SSD subtypes that are discussed in the literature?

• A. Phonetic disorders versus phonemic disorder
• B. Phonological articulation versus lexical semantics
• C. Motor planning vs phonological planning
• D. Speech delay vs speech disorder

Answer: (A)

The two proposed subtypes are phonetic (articulation) disorders and phonemic (phonological) disorders. Phonetic disorders involve the physical production of sounds—the motor aspect of articulation. A child with this type has difficulty shaping and pronouncing sounds correctly, often manifesting as distortions or imprecise articulation due to motor execution issues. Phonemic disorders, on the other hand, concern the sound system and mental representations of phonemes. Here, the problem lies in how sounds are organized and used in the language, leading to systematic pattern-based errors (like substitutions or simplifications) that reflect phonological knowledge rather than just motor trouble. This distinction is commonly discussed in SSD literature because it directs different approaches: articulation-focused therapy for phonetic issues and phonological-based intervention for phonemic issues. The other options mix in areas not typically treated as SSD subtypes—lexical semantics relates to meaning, motor versus phonological planning is more about stages of speech production rather than the superficial vs systematic nature of errors, and broad labels like speech delay versus speech disorder don’t capture the specific distinction between articulation and phonology.
