Abstract

The results of this study indicated that participants accurately and reliably differentiated normal from abnormal speech samples. Thus, all groups proficiently identified disordered cases while limiting the number of misdiagnoses; however, some degree of task difficulty was noted and clinical biases were evident. For this research question, group trends indicated that the most experienced group of participants adopted a more lenient diagnostic criterion as compared to the intermediate and novice groups.
