SFARI Investigator Website

Mark Clements is the Joseph M. Pettit Professor Emeritus of Digital Signal Processing within the school of Electrical and Computer Engineering at the Georgia Institute of Technology. He received his S.B. (bachelor’s), S.M. (master’s), E.E. (professional engineer’s) and Sc.D. (doctorate) degrees in 1976, 1978, 1979 and 1982, all in electrical engineering and computer science from Massachusetts Institute of Technology. During his graduate work, Clements was supported by a National Institutes of Health fellowship for research in hearing prostheses and a corporate sponsorship for the development of real-time automatic speech recognition systems.

His research interests involve digital processing of speech signals, including the application of digital speech technology to sensory aids for the hearing impaired and automatic recognition of speech in adverse conditions. Some of the interesting problems arising from these applications include enhancement of speech in noise, formulation of robust perceptual distance measures and real-time implementation. Clements also does work in efficient coding of speech signals, auditory modeling for improved speech analysis, speech production modeling, general digital signal processing and pattern recognition. Recent work has involved application of speech analysis methods to children’s speech recorded in naturalistic environments.

Clements is a member of the Acoustical Society of America and a Fellow of the Institute of Electrical and Electronics Engineers (IEEE). He is also the founder and past director of Nexidia Inc., an Atlanta-based speech technology company.
