Dr. Kaitlin Lansford is Professor at Florida State University (FSU) in the School of Communication Science and Disorders and Associate Dean for Research and Creative Activities for CCI. She iis also the director of the Motor Speech Disorders Lab (MSDLab) at FSU. Lab members of the MSDLab conduct research on dysarthric speech perception and adaptation. Exploiting the relationship between the degraded acoustic signal and the nature of the listener’s challenge has the potential to be a powerful paradigm for studying intelligibility deficits in dysarthria because results may point directly toward intervention targets, as well as inform theory on the perception of degraded speech. Her current work focuses on perceptual training, which offers a promising avenue for improving intelligibility of people with dysarthria by offsetting the communicative burden from the patient onto their primary communication partners.
