Computer Enhancement and Synthesis Research: Analysis and Modification of Human Singing
Unlike speech, which has been studied extensively in the signal processing community for decades, relatively little attention has been given in this community to the analysis and modification of human singing.
Consequently, many fundamental questions remain unexplored with respect to singing voices. For instance, how can one effectively model human singing in a way that enables assessment of voice quality? How can one digitally modify the voice of a poor singer and resynthesize that voice to sound like a professional singer? And, how can one digitally recreate the singing voice of a legendary singer like Nat “King” Cole or Frank Sinatra?
These questions and others similar in spirit have motivated the work that
will be presented in this talk. While the problem and issues suggested above
have in no way been solved, significant steps have been taken toward realizing
these goals. This talk will present an overview accompanied by demonstrations
of new developments in our enhancement and synthesis research.
Mark J. T. Smith
Michael J. & Katherine R. Birck Professor and Head of Electrical and Computer Engineering, Purdue University
Mark J. T. Smith became head of Purdue University’s School of Electrical and Computer Engineering in January 2003. He assumed this role after serving as both a faculty member of electrical and computer engineering and an assistant to the president at the Georgia Institute of Technology. He won the Georgia Tech Outstanding Teacher Award in 1988.
After obtaining his BS in electrical and computer engineering from MIT (1978), Smith earned both his master's and doctoral degrees in electrical engineering from the Georgia Institute of Technology (1979 and 1984, respectively). He has also been active as a journal associate editor, conference and workshop organizer, and technical committee chair in the IEEE Signal Processing Society. His areas of interest include speech and image processing, filter banks and wavelets, and object detection and recognition.
Smith was a U.S. National Champion in fencing in 1981 and 1983, and also earned a spot on the 1980 and 1984 Olympic teams.
