Which characteristic is NOT typically used to distinguish dysarthria types?

• A. Strength
• B. Speed
• C. Coordination
• D. Accent

Answer: (D)

When evaluating dysarthria, clinicians distinguish types by how the speech motor system is affected, focusing on three main dimensions: strength, speed, and coordination of the articulators. Strength refers to how much force the jaw, lips, and tongue can exert. Speed looks at how quickly these articulators move during speech. Coordination concerns the precision and timing of their movements.

Accent, on the other hand, is about the way speech sounds influenced by language, dialect, or individual habit. It reflects linguistic and prosodic characteristics rather than the underlying motor impairment pattern. So while a dysarthric speaker might sound more or less accented depending on articulation, accent itself is not a criterion used to classify the type of dysarthria. That’s why accent is not typically used to distinguish dysarthria types.
