Definition |
A type of speech disorder characterized by slurring, breathiness, wetness, or straining. A type of speech disorder resulting from disturbances of muscular control of the speech mechanisms, including paralysis, weakness, or incoordination of the respiratory muscles, larynx, tongue, lips, jaw and other articulators. The origin of dysarthria may be peripheral (e.g. facial paralysis, loss of teeth) or central (e.g. basal ganglia disease, cerebellar disease). Dysarthric speech is characterized by slurring, breathiness, wetness, or straining. Articulation errors in dysarthria are produced consistently in voluntary and involuntary speech activities, and this distinguishes them from inconsistent articulation errors associated with apraxia of speech.
