It can be difficult to get your clients to repeat the target patterns without getting bored, but the exercises on these CDs make it easy. Children love the colorful characters and are happy to talk about them!

Evidence Base: Results have shown that training children to produce more complex (marked) structures such as affricates results in learning of simpler but related unmarked structures (e.g., fricatives). Similarly, training clusters results in generalization to singletons, and training clusters with greater sonority (e.g., /kw/) affects learning of clusters with lesser sonority (e.g., /bl/) (Thompson, 2007).
Evidence Base: Computer-assisted instruction has also been compared to treatment administered by speech-language pathologists. In a series of studies, both modes of treatment presentation were demonstrated to be comparable in effectiveness and efficiency (Gierut, 1998). The results showed that children and speech-language pathologists alike preferred the drill-play combination of teaching to enhance phonological improvements (Gierut, 1998).
