"Of the included interventions, the Hanen Program in combination with focused stimulation conclusively improved speech and language outcomes, specifically increasing vocabulary size, expanding phonetic inventories, and increasing syllable structure repertoires" (p. 1).
"Because the overall effectiveness of responsivity education/prelinguistic milieu teaching and modeling alone as an intervention technique could not be derived from the current studies, further research is recommended" (p. 1).
"Of the included intervention techniques, expansion, recasting, parallel talk, child-directed speech, visual cues, feedback, and increasing interaction opportunities showed large effects on increasing the mean length of utterances, the total number of words, the number of different words, and the percentage of intelligible utterances" (p. 1).
