A virtual therapist (VT) capable of modeling visible speech and directing speech and language therapy is presented. Three perspectives of practical and clinical use are described. The first is a description of treatment and typical roles that the VT performs in directing participation, practice and performance. The second is a description of techniques for modeling visible speech and implementing tele-rehabilitation. The third is an analysis of performance of a system (AphasiaRx TM) for delivering speech and language therapy to people with aphasia, with results presented from a randomized controlled cross-over study in which the VT provided two levels of cuing. Compared to low cue treatment, high cue treatment resulted in 2.3 times faster learning. The paper concludes with a discussion of the benefits of speech and language therapy delivered by the VT.
