Abstract: Phonetic hand cueing systems are widely used by speech-language pathologists and promoted in commercial programs, yet empirical evidence for their effectiveness remains limited. This research series evaluates the systematic use of phonetic hand cues as a stimulus control transfer procedure and compares their impact to other commonly used differential reinforcement strategies. Results demonstrate rapid acquisition of hand cues, improved articulation at syllable and word levels, and enhanced intelligibility in natural communication contexts. Formal testing further confirms reductions in speech sound errors. Integration of hand cues within ABA and school-based programs—from target selection to generalization across verbal operants—will be illustrated with video examples. Findings extend prior case study evidence, supporting phonetic hand cues as a promising intervention for children with autism who present with limited vocal repertoires.
