Acoustic, Kinematic, And Auditory Perceptual Characteristics Of Clear Speech, Kristin L. Greilick

Masters Theses

This study characterized the speech motor transformations that underlie speech clarity changes in a group of 49 healthy young speakers. Clarity judgments based on auditory perception of the speech samples were determined by a panel of 30 undergraduate and graduate students. This study specifically aimed to characterize (1) the auditory-perceptual judgments of clarity, (2) the acoustic measures of clear and causal speech, (3) the temporal and spatial features of articulatory movements of clear and casual speech, and (4) test the hypothesis that auditory perceptual scaling of clarity (perceptual salience) would be associated with kinematic indicators of physical effort.

Dialect Density And Discourse Maturity Of African American Elementary Students, Brandi Lynette Newkirk

Masters Theses

This was a report of an investigation of the effects of dialectal features in African American students' narratives on discourse ratings by trained judges. The question addressed in this research was whether dialectal features influence judges who are evaluating discourse. Graduate students in speech-language pathology (n = 18) learning to analyze discourse samples served as the judges. Two versions of narratives (n = 27) written by third- and fourth-grade African American students (the original version and the edited version) were used to determine if narratives that contain dialectal features would be rated lower. The judges were trained in narrative discourse …
