The report summarizes a project investigating effects of biofeedback on nine secondary students with speech problems including stuttering, vocal nodules, articulation problems, and cerebral palsy. It is explained that a portable electromyograph was used to give the students immediate visual and/or auditory feedback. Results listed include that Ss lessened their number of misarticulations, Ss found talking was easier as they became more relaxed, and Ss who stuttered could lessen the severity of their repetitions and/or blocks but did not necessarily reduce their frequency of repetitions. Project costs, resources, and activities are charted and briefly discussed. (CL)
