In thinking about intervention design for SSD, which statement best reflects the role of surface speech characteristics?

• A. They determine the exact phonetic alphabet used in therapy
• B. They require identical treatment across all children
• C. They indicate the need for individualized interventions
• D. They are unaffected by etiology

Answer: (C)

Surface speech characteristics guide how therapy is planned for each child. When you listen to what a child actually produces—the sounds they can or cannot produce, the patterns of errors, syllable structures, and overall intelligibility—you see that each child’s profile is unique. Because of that variability, intervention needs to be tailored to the individual rather than applying one fixed approach to everyone.

The idea isn’t that surface features alone determine a rigid protocol or that everyone gets the same treatment. It’s that observable speech outputs shape target selection, sequencing, and methods so therapy fits the child’s specific profile. Etiology can influence decisions too, but the key point here is the necessity for individualized intervention based on how the child’s surface speech presents.
