The PROMPT System Prompts for Restructuring Oral Muscular Phonetic Targets) was formally devised by D. Hayden in 1980 after working extensively with/and researching varied speech production disordered populations. Since that time, over a span of 19 Years, Deborah has continued to develop PROMPT as a Technique, System, Approach, and Philosophy. PROMPT is based on neurological, anatomical, cognitive-linguistic and motor theory principles. It has been said that “PROMPT directly translates the neuro-muscular movements required for the phonemic system, connects them to linguistic-codes and articulatory sequences for communicative interactions”. Visit the PROMPT Institute
