There exist very few effective treatments that ease the intelligibility burden of dysarthria. Perceptual training offers a promising avenue for improving intelligibility of dysarthric speech by offsetting the communicative burden from the speaker with dysarthria on to their primary communication partners-family, friends, and caregivers. This project, utilizing advanced explanatory models, will permit identification of speaker and listener parameters, and their interactions, that allow perceptual training paradigms to be optimized for intelligibility outcomes in dysarthria rehabilitation. This work addresses this critical gap in clinical practice and sets the stage for extension of dysarthria management to listener-targeted remediation-advancing clinical practice and enhanced communication and quality of life outcomes for this population.
