How does the NDP3 treatment differ from other approaches?
NDP3 has been described by some as a very structured articulation therapy approach. However, although it is true that the focus is on speech output and developing motor programming and planning skills, there are a number of features which make it different to conventional articulation therapy:
In the NDP3 approach, a number of single sounds are worked on at a time, whereas in articulation therapy, the focus is on working on one sound at a time.
The NDP3 approach starts from a child’s strengths, utilising whatever speech skills the child already has, whereas articulation therapy works on a child’s weaknesses ie sounds s/he cannot currently produce.
In articulation therapy, once a sound is acquired, therapy focuses on establishing the sound in initial, medial and final positions in words. However, in NDP3, the emphasis is on developing a complete inventory of speech sounds, learning to use sounds at different levels of phonotactic complexity and on developing a contrastive system at each of these levels.
In articulation therapy, the focus is mainly on consonant sounds, whereas NDP3 involves vowel and consonant sounds and also works on suprasegmental aspects of speech.
In the UK, NDP3 is the only published resource, which provides an approach and materials for working with children presenting with dyspraxic difficulties.
NDP3 uses picture symbols, but it can be used in conjunction with other cueing systems e.g.: cued articulation, orthographic cues and diagrammatic cues.
