Listener Training for Improved Intelligibility of People With Parkinson's Disease

Listener training offers a promising avenue for improving communication for people with dysarthria due to Parkinson's disease by offsetting the intelligibility burden from the patient onto their primary communication partners. Here, we employ a repeated-measures, randomized controlled trial to establish the efficacy of listener training for patients with PD and their primary communication partners. This translational work will establish a new realm of clinical practice in which the intelligibility impairments in PD are addressed by training partners to better understand dysarthric speech, thus elevating communication outcomes and participation in daily life.
