Carol Espy-Wilson is a professor in the electrical and computer engineering department at the University of Maryland at College Park, where she also directs the Speech Communication Lab. An electrical engineer whose research focuses on understanding the relationship between acoustics and articulation, she is modeling speech production, studying speech perception, developing signal-processing techniques that capture relevant information in speech, and using the knowledge gained to develop speech technologies.
During the fellowship year, Espy-Wilson will focus on the noise robustness of a probabilistic landmark-based speech-recognition system. The development of this technology is a collaborative effort between researchers in engineering, linguistics, computer science, and rehabilitation science. Specifically, Espy-Wilson will refine an auditorily motivated enhancement algorithm to improve the signal-to-noise ratio of the signal prior to its parameterization and extend the recognition framework to allow for the reweighting of acoustic information based on the level and type of noise.
Espy-Wilson earned her PhD in electrical engineering and computer science from the Massachusetts Institute of Technology. She received a National Science Foundation Minority Initiation Award, the Clare Boothe Luce Professorship, a National Institutes of Health (NIH) Independent Scientist Award, and a Honda Initiation Grant. She is a fellow of the Acoustical Society of America (ASA), where she currently serves as chair of the Technical Committee on Speech Communication and associate editor of Acoustics Today; a senior member of the Institute of Electrical and Electronics Engineers; and a past member of the NIH Language and Communication Study Section.
