ECE 537
Speech Processing Fundamentals

Credit:  4 hours.


Provides an intuitive understanding of speech processing by the auditory system, in three parts. I: The theory of acoustics of speech production, introductory acoustic phonetics, inhomogeneous transmission line theory (and reflectance), room acoustics, the short-time Fourier Transform (and its inverse), and signal processing of speech (LPC/CELP/VQ). II: Psychoacoustics of speech perception, critical bands, masking (JNDs), and the physiology of the auditory pathway (cochlear modeling). III: Information theory entropy, channel capacity, the confusion matrix, state models, EM algorithms, and Bayesian networks. Classic papers on speech processing and speech perception assigned and presented by student groups. Matlab (or equivalent) programming is required for many of the homeworks. Prerequisite: ECE 410.
