There are a number of intervention programs available including the Kaufman Speech to Language Protocol utilizing behavioral principles to aide in motor-speech shaping (Kaufman, 1995), Nuffield Dyspraxia Program, which focuses on speech output and motor programming skills (Williams & Stephens, 2010), and Training Syllable Sequences focused on using nonsense syllables to train motor planning flexibility (Velleman, 2003; Velleman & Strand,
