Children with IDD typically have what kind of phonological characteristics?

Children with intellectual and developmental disabilities (IDD) often exhibit speech patterns that can be less intelligible than their typically developing peers. The phonological characteristics associated with IDD frequently include challenges in articulating sounds, which can lead to unclear or unintelligible speech. This unintelligibility can persist into adulthood for some individuals with IDD, making it a significant characteristic of their communication profile.

This persistence of unintelligibility relates to the potential for slower speech development and the presence of phonological processes that might affect their ability to communicate clearly. Factors such as cognitive delays, motor skills challenges, and the possible presence of additional disabilities can compound these issues. Hence, the characteristic of unintelligible speech throughout adulthood highlights the lasting impact of IDD on phonological development and the importance of tailored interventions to improve communication abilities.
