Charissa Lansing received her Ph.D. from The University of Iowa in 1984. She is an associate professor in the University of Illinois at Urbana-Champaign's Department of Speech and Hearing Science and a part-time faculty member in the Beckman Institute Human Perception and Performance Group. Her fields of profession interest are visual processes in speech perception, auditory-visual speech perception, hearing aids and sensory-prosthetic devices, and rehabilitative audiology.


Visiting Scholar U of I-KULeven Faculty Exchange Program, University of Leuven, Department of Psychology, Laboratory of Experimental Psychology, (2004); FIRST Award, National Institutes of Health, (NIH), National Institute on Deafness and Other Communication Disorders (NIDCDS) (1995-99); Fellow, The Center for Advanced Study, University of Illinois at Urbana-Champaign (1994).


Charissa Lansing's work deals with how people attend to, select, and integrate visual and auditory information to process language, core components of research in the areas of human computer interaction, and biological intelligence. Lansing's collaborative research efforts at the Beckman are focused in three basic areas: (1) Visual processes in speech perception. This project is designed to test hypotheses about attentional and visual processes in speech perception tasks in relation to specific stimulus factors (in collaboration with George McConkie, HPP group). This knowledge is critical to the development of intelligent algorithms for speech processing and effective sensory aids that must function in real-world settings. (2) Quantification of facial motion. This project aims to characterize the spatial and temporal characteristics of face motion in speech production and the expression of human emotion (in collaboration with Professor Thomas Huang and members of the IFP group). The accurate characterization of facial motion in human communication is a prerequisite to the study of visual processes in speech perception and the development of a real-time, voice driven synthetic talking face. (3) Sensory aids for speech perception. Collaborative interactions with Albert Feng and Bruce Wheeler (NT group), William O'Brien (BRL group), Douglas Jones (ECE), and Robert Bilger (Speech and Hearing Science) have resulted in progress toward the development and evaluation of algorithms capable of extracting and localizing desired signals in real-world, acoustically cluttered environments. If applied to sensory devices, such as hearing aids, and advanced acoustic processors, these algorithms may enhance performance in speech perception for humans and computers.
