PROMPT therapy is a particular approach to assisting children with speech difficulties using motion-based prompts. While PROMPT training is not easily available in South Africa, practitioners like Karien Marais offers introductory seminars on PROMPT in her capacity as a certified PROMPT therapist, and this useful approach is gaining momentum in the South African context. Here's a YouTube clip with a lovely short visual demonstration of how PROMPT works. Some of these techniques are integrated into Karien's treatment of children with speech-sound disorders, as illustrated in her full, CEU-accredited talk available here.
