Children with phonological disorders have impairments to their underlying rule-system of language. In other words, the child is confused about the way in which the vowels and consonants of the language may be combined to form their words and sentences.
Children with this type of speech disorder tend to be very difficult, if not impossible, to understand. Fortunately, phonological errors typically have some predictable patterns to them. It is these patterns that make this type of speech problem fairly easy to correct with the right type of activities and materials.
Recommended games and activities are effective for working with children with phonological disorders and may also be used in traditional articulation therapy with great success.
