dysarthria
Dysarthria is a neurologic speech disorder caused by paralysis, weakness, improper muscle tone or incoordination of the muscles of the mouth. Dysarthria is not a disorder of language.
Symptoms of dysarthria may include speech that is slurred, slow, and difficult to produce and/or understand. The person with dysarthria may also have problems controlling the pitch, loudness, rhythm and voice qualities of their speech. Associated problems may include drooling and difficulty chewing and swallowing. Unlike apraxia of speech, the speech errors that occur with dysarthria are highly consistent from one occasion to the next.
