Speech Communication Courses


6.501: Sound, Speech, and Hearing.

Introduces the physical, physiological, and psychological bases of auditory communication. Sound propagation in tubes, sound radiation, properties of neural and muscular elements, the vocal tract and speech generation, signal transmission in the auditory system, perception of attributes of speech and speechlike sounds, and the linguistic units that underlie speech events. Disorders of human communication. Alternate years.
K. N. Stevens, L. D. Braida

6.541J: Speech Communication

Survey of structural properties of natural languages, with special emphasis on the sound pattern. Physiology of speech production, articulatory phonetics. Acoustical theory of speech production; acoustical and articulatory descriptions of phonetic features. Perception of speech: the auditory capabilities of humans; evidence for perceptual correlates of phonetic categories. Applications to recognition and generation of speech by machine. Recommended prerequisite: mathematical background equivalent to 6.003.
K. N. Stevens, S. J. Keyser

6.542J: Laboratory on the Physiology, Acoustics, and Perception of Speech

Experimental investigations of speech processes. Topics: a) measurement of articulatory movements, b) measurements of pressure and volume velocity, c) computer-aided waveform analysis and spectral analysis of speech, d) synthesis of speech, e) perception and discrimination of speechlike sounds, f) speech prosody, g) hidden Markov models for speech recognition, and other topics. Recommended prerequisites: 6.501, 6.002 or 18.03. Alternate years. 4 Engineering Design Points.

6.551J: Acoustics of Speech and Hearing

Electric-acoustic analogies. Review of basic ideas of circuit theory; natural frequencies, two-ports, reciprocity, energy, and power. Laws of acoustics. Waves in one dimension. Acoustic impedance. Natural frequencies in tubes. Lumped approximations. Losses, non-uniform plane waves, horns. Room acoustics. Sound sources and microphones. Concepts applied to speech production and hearing. Laboratories demonstrate measurement methods, data presentation, and tests of theory. 4 Engineering Design Points.
