As ultrasound imaging gains popularity in speech research, an important question to address is the reliability of the measures taken from these images. This study examines the reliability of hand measures of ultrasound data collected by graduate student researchers in the University of South Florida's speech science lab. Speech production data from Ultrasound analysis of velar fronting (Wodzinski, 2004) and Ultrasound study of errors in speech production (Frisch, 2003) were used to obtain inter-rater reliability measures. This study compares the raters choice of video frame depicting alveolar or velar closure image, anterior and posterior points of closure, tongue blade and velar angle measurements, as well as a measurement of the tongue dorsum distance from the ultrasound probe.
