Speech disorders affect how sounds and words are articulated.
- Dysarthria is a neurologic motor speech disorder characterized by slow, weak, uncoordinated movements of the speech musculature. It can be congenital (e.g., cerebral palsy) or acquired (e.g., stroke, brain injury, Parkinson�s disease).
- Apraxia refers to a neurologic motor speech disorder resulting in difficulty coordinating and sequencing muscle movements to produce sounds in syllables and words.
- Speech sound disorders in children include problems with articulation (producing sounds) and phonological processes (sound patterns) resulting from a developmental delay or associated with a physical impairment such as cleft lip and/or palate or a hearing loss.
