This study investigated changes in vocabulary and speech production in response to storybooks embedded with specialized language prompts and speech recasts. Six children received intervention, 3 with cleft palate (CLP), displaying speech-language delays, and 3 with nonclefts, each 12-24 months of age. A multiple baseline design across behaviors was implemented by a clinician. Results indicated all children increased use of target vocabulary and production of stop consonants, while reducing compensatory articulation errors. Generalization of targets to a picture-naming task, a free-play task, and to the home was observed. Effect sizes were moderate-to-high. Children with CLP required more sessions to achieve criterion. Analysis of 20-minute language samples, collected pre- and post-intervention, showed that both groups increased their vocabulary and speech measures.
