In a new study, Elizabeth Krajewski, doctoral candidate in the Penn State Department of Communication Sciences and Disorders, worked with Jimin Lee, associate professor of communication sciences and disorders, to examine the use of vowel intelligibility testing for assessing how weak or weakening speaking muscles affect speech intelligibility in people with amyotrophic lateral sclerosis (ALS). Results indicate it could be a useful clinical tool when providing care and intervention services for this population.
