Lecture, two hours; laboratory, two hours; outside study, eight hours. Prerequisites: courses 113, 132A, 141. Advanced systems design integrating communications, control, and signal processing subsystems. Different project to be assigned yearly in which student teams create high-performance designs that manage trade-offs among subsystems.
Graduate level course on the theory and applications of digital processing of speech signals. Mathematical models of human speech production and perception mechanisms, speech analysis/synthesis techniques including linear-prediction, filter-bank models, and homomorphic filtering. Applications to speech synthesis, automatic speech recognition and hearing aids.
Prerequisites: solid understanding of linear systems and the fundamentals of Digital Signal Processing (EE 113 or equivalent).
Text: Digital Processing of Speech Signals, Rabiner and Schafer
Advanced techniques used in various speech-processing applications, with focus on speech recognition by humans and machines, and on speech and audio coding for digital communication channels. Physiology and psychoacoustics of human perception. Dynamic Time Warping (DTW) and Hidden Markov Models (HMM) for automatic speech recognition systems, pattern classification, and search algorithms. Aids for the hearing impaired.

Lecture, three hours; laboratory, two hours. Prerequisite: one prior linguistics course or course 20 (Introduction to Linguistics) concurrently. Phonetics of a variety of languages and phonetic phenomena that occur in languages of the world. Extensive practice in perception and production of such phenomena.
Lecture, four hours; discussion, one hour. Prerequisite: course 103. Survey of principal techniques of experimental phonetics. Use of laboratory equipment for recording and measuring phonetic phenomena.
Prerequisite: course 120A (Phonology I). Preliminaries to speech analysis. Functional anatomy of vocal organs; fundamental principals of acoustics and of acoustic theory of speech production; issues in perception of speech; nature and design of feature systems for phonetic and phonological analysis.
Prerequisite: course 103 or equivalent. Use of laboratory equipment to investigate articulatory, acoustic, and perceptual properties of speech. Topics include experimental design and statistics; theoretical basis of acoustic structure of speech sounds; computer-based speech processing, analysis, and modeling; perceptual and acoustic evaluation of synthetic speech.
Lecture, three hours; discussion, one hour. Prerequisites: courses 171 (Principles of Neurobiology) or M175A-M175B (Neuroscience: from Molecules to Mind), or equivalent. Structure and function of sense organs. Adoption of quantitative and comparative approach to provide insight into evolution of sense organs in both invertebrates and vertebrates.
Lecture, three hours; discussion one hour. Prerequisites: Mathematics 3C, Physics 6C, consent of instructor. Open to qualified undergraduates with consent of instructor. Physical properties of animal signals and physiological mechanisms underlying their generation and reception. Lectures treat signal analysis, signal transmission, and receptor design in light of constraints placed on each of the sensory modalities. Examples of communication systems using visual, auditory, chemical, electrical, and magnetic cues, with emphasis on biological adaptations for efficiently signaling species-specific information.
