Articulation, or more specifically course articulation, is the process of comparing the content of courses that are transferred between postsecondary institutions such as TAFE institutes, colleges or universities.
What causes an articulation disorder? An articulation disorder may be attributed to hearing loss, neurological disorders, physical impairments such as cleft lip or palate, vocal abuse or misuse, hypotonia, oral-motor skills, or difficulty with placement of articulators. However, the cause of the disorder is often unknown.
