This study examined the treatment efficacy of a behavioral speech therapy protocol for adult cochlear implant recipients. Three subjects participated in a structured, individual therapy program based on behavioral principles and methods, including the use of modeling, visual prompts, and shaping (i.e., successive approximations) to elicit target behaviors (i.e., speech sounds); response contingent reinforcement for correct productions; and corrective feedback for incorrect productions. A multiple baseline across behaviors and participants design was used to examine the effectiveness of the behavioral therapy program on improving the production of target speech sounds. In addition, pretest and posttest scores from the Arizona Articulation Proficiency Scale, Third Revision (Arizona 3) and measurement of speech errors during spontaneous speech were compared. The generalization of newly trained speech skills to untrained words and to spontaneous speech was addressed. The results of this study provided evidence supporting the overall effectiveness and efficiency of a behavioral speech therapy program in improving percent correct speech production in adult cochlear implant recipients. These findings support the application of behavior analysis techniques to speech correction in adults with cochlear implants. Implications for future research and the development of oral-aural rehabilitation programs for adult cochlear implant recipients are discussed.
