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.

Context Recall the arguments of A. Damien Martin (1974). See also the papers in Kean (1985) and more recent polemics, such as Grodzinsky (1989). “Anarthric”) phonetic disintegration can exist in isolation from aphasia and from dysarthria. Their patient had cortico-subcortical softening of the inferior half of the left precentral gyrus, with Broca’s area nevertheless intact. Although Lecours and Lhermitte called this “pure” form of phonetic disintegration “a relatively infrequent form of aphasia” (p. 109), the patient had no other aphasic symptomatology.
