Abstract
This study examined the relative benefit of three interventions (i.e. physiological, behavioural, and pragmatic) designed to facilitate speech recognition software use. Participants were 15 adults with dysarthria associated with a variety of aetiological conditions, including cerebral palsy, Parkinson's disease, and motor neuron disease. Results suggested no clear dysarthric profile that would preclude at least some degree of speech recognition system use. Participants demonstrated systematic improvement in their dictation rates regardless of treatment order. The physiological treatment produced significantly higher dictation rates overall than the behavioural—but not the pragmatic—treatment. This finding suggests that improvement was not simply a function of software training, at least for the physiological treatment. This conclusion also was supported by changes in the participants' speech production during a post‐treatment assessment.
