Abstract
Purpose: This research study examined the effect of high- vs. low-variability exemplar production practice in the treatment of developmental speech sound disorder.

Method: Sixteen children with developmental speech sound disorder received treatment for their speech sound errors. Treatment targeted singleton speech sounds in word-initial position, five-days per week for five weeks. Half of the children practiced their speech sound target in 24 unique words (high-variability exemplar practice condition) and the other half practiced production of their speech sound target in six unique words repeated four times each (low-variability exemplar practice condition). Generalization probes were used to measure speech sound target acquisition.

Results: Both the high-variability and low-variability conditions produced significant change in the children’s use of their speech sound target. No statistical difference was found between conditions; however, the low-variability condition evidenced slightly larger gains.

Conclusion: Daily treatment sessions of short duration are a viable service-delivery model for the treatment of developmental speech sound disorder. Differences in exemplar variability practice did not significantly influence treatment outcomes for children with developmental speech sound disorder.
