HCSnet Seminar: Dr Kristin RosenSummaryRosen has introduced a new approach to the objective analysis of speech. Her approach involves analysis of speech segment duration including description involving lognormal distributions. The analytic techniques pioneered by Rosen and others provide an objective platform for the quantification of fluency in healthy and disordered speech. Rosen will discuss applications involving dysarthric speech and other communication disorders, and discuss the implications for the language sciences generally. RelevanceThe seminar will be of interest to scholars from diverse disciplines including cognitive psychology, speech science, speech pathology, communication disorders, linguistics and second language learning. The methodology developed in parallel by Kristin Rosen and scientists from UWA provides a critical platform for the objective measurement of natural language. The critical parameters can be derived from natural language or conversation, and they are therefore suitable for a variety of clinical and industrial applications. The parameters provide an objective analysis of the bio-acoustic pattern of speech, and they represent a significant advance relative to the rating procedures and de-contextualized tasks that currently dominate measurement in this area. Kristin's presentation will include illustrations and applications from people with neurogenic motor / speech disorders. Kristin Rosen's research is directly relevant to work being implemented by Professors Kirsner, Dunn (now at the University of Adelaide) and Hird, and to the substantial group of doctoral students (6 with 4 applications in hand) working with a comparable technique at UWA. In addition to the public seminar, the visit will be the occasion of a series of technical meetings to facilitate the design and development of techniques and parameters being developed by the Queensland and UWA groups. BioDr Kristin Rosen completed a PhD on the classification of voice quality associated with Parkinson's disease at the University of Wisconsin-Madison in 2005. She has recently been appointed as National Multiple Sclerosis Society Research Fellow in the Division of Speech Pathology in the School of Health and Rehabilitation Sciences at the University of Queensland. Dr. Rosen's doctoral thesis examined classification of voice quality associated with Parkinson's disease. With her expertise in signal processing and acoustic analysis, she has pioneered new methods of analyzing of conversational speech, an area that has been neglected in research of motor-speech disorders. Additional workshopsThe following workshops will be held during Dr. Rosen's visit on Tuesday, November 28:
