Motor Speech AOS Practice Test 2026 - Free Apraxia of Speech Practice Questions and Study Guide

Apraxia of speech affects how the speech movements are planned and sequenced, which shows up as timing and rhythm problems alongside distortions in the sounds themselves. Because the motor plans for articulating consonants and vowels aren’t produced smoothly, speakers often distort segmental aspects (the actual sounds) and prosodic aspects (timing, stress, and intonation). This combination leads to erratic articulation and longer, slower segments, with unusual pauses and extended durations. That blend of sound distortions plus altered timing is the hallmark, making the statement that describes distortions across both segmental and prosodic features with extended durations the most accurate.

The other options point to language content or memory rather than motor planning. They describe semantic retrieval, grammar processing, or memory recall, which are not the primary areas impacted in apraxia of speech.
