The course emphasizes processing of the human speech waveform, primarily using digital techniques. Theory of speech production as related to signal models in time and frequency domains is covered, as well as the measurement of model parameters, short-time Fourier spectrum, and linear predictor coefficients. Speech coding, recognition and synthesis, and speaker recognition are also included.
Some consideration is given to speech processing hardware.
Software projects are required. Prerequisites 525.427 Digital Signal Processing and 525.414 Probability and Stochastic Processes for Engineers . Instructor Joe Campbell received a B.S.E.E. from Rensselaer Polytechnic Institute in 1979, an M.S.E.E. from The Johns Hopkins University in 1986, and a Ph.D. in EE from Oklahoma State University in 1992. Dr. Campbell has been employed by the Department of Defense since 1979. From 1979 to 1990, he worked in the Narrowband Secure Voice Technology research group.
