Which option best exemplifies surface characteristics of speech in SSD?

• A. Etiology of SSD
• B. Underlying speech processes
• C. Surface characteristics of speech
• D. Genetic factors

Answer: (C)

Surface characteristics are the sounds and patterns listeners actually hear in speech—the visible output of a speech sound disorder. This includes articulation errors, substitutions, distortions, omissions, and any unusual prosody or pacing that you can perceive in connected speech. The option that names surface characteristics directly is the best example because it points to the perceptible speech signal itself, not to why the disorder occurs (etiology), the hidden mental representations or motor planning behind speech (underlying processes), or genetic influences. Those other factors describe causes or internal processes, whereas surface characteristics focus on what the speaker’s actual speech sounds like.
