Which type of errors is most common in AOS?

Which type of errors is most common in AOS?

• A. Articulation errors
• B. Grammatical errors
• C. Semantic errors
• D. Prosodic errors

Answer: (A)

Apraxia of speech is a motor planning and programming issue, so the most common errors you’ll see are in articulation—sound distortions, substitutions, and sequencing problems on individual sounds, especially consonants, often with visible groping and variability across attempts. This reflects the difficulty in planning precise movements for speech rather than problems with word meaning or sentence structure. Grammatical and semantic errors point to language or comprehension problems rather than the motor planning deficit seen in AOS. Prosodic changes can occur, but they’re less central than the frequent articulation distortions.
