Abstract

Rate control or pacing treatments for AOS have been reported to result in increased accuracy of sound productions without instructions concerning articulation. A combined multiple baseline and ABCA design was used to examine the effects of repeated practice alone and repeated practice plus rate/pacing control on consonant production accuracy in five speakers with moderate AOS and aphasia. All speakers demonstrated improvements in articulatory accuracy with repeated practice alone. Rate/pacing treatment was not necessary in some cases because high levels of performance were achieved with repeated practice alone. When applied, rate/pacing treatment resulted in additional gains.
