In 1938, Travis and Rasmus commented on a particular problem in pathology. They said, "From every angle, an adult with a disorder of articulation presents a much more serious problem than a child with such a defect" (40. p. 218). Their statement is an appropriate current evaluation of the same problem. The American Speech and Hearing Association's Committee on the Midcentury White House Conference reported that the incidence of articulatory disorders was equal, 3.3% for both children and adults in the United States (1). In 1962, Dopheide found that 36 out of 2,087 of the freshman entering Western Michigan University exhibited defective articulatory ability (13). A perusal of studies reported reveals that most of the studies have been of children's faulty articulation (28, 11, 12, 23, 29). Adults' articulatory problems have not received such intense study (17, 40, 27).
