Perceptual ratings of vocal characteristics and voicing features in untreated patients with unilateral vocal fold paralysis

As a result of reading this manuscript the reader will (1) gain an understanding of types of perceptual scales and how to develop the set of vocal characteristics to be used in distinguishing patients with UVFP and those without, (2) learn which vocal characteristics listeners are able to use to successfully distinguish between patients with UVFP and those without and (3) understand the possible role for perceptual ratings in tracking changes in vocal characteristics in subjects over time following treatment or spontaneous recovery of function.
