Speech is a highly dynamic process involving intricate coordination of the motor and perceptual systems. The physiological, physical, and mathematical complexity of the underlying processes has posed a significant challenge to speech researchers for many decades. Recent advances in physiological and perceptual methods, as well as innovations in computational approaches and models raise the possibility that dynamics may actually carry the bulk of information in speech and thu that is, it may represent more than just one aspect of verbal communication. Continued investigation in these areas promises to yield significant new insights into the dynamic properties of speech over the next few years.

This symposium will examine the dynamics of speech from the perspectives of production, perception, physiology, computation, and modeling, in an attempt to provide a truly interdisciplinary framework with which to understand spoken language. Each of the primary presentations will be of 30 minutes duration, providing ample time for discussion with members of the audience. In addition, there will be two panel discussions focused on specific topics germane to more general issues pertaining to speech dynamics.

The symposium will be held in the Sibley Auditorium at the Bechtel Center on the Berkeley campus, with opening remarks beginning at 8:50 and the first speaker beginning at 9:00 AM. Those attending the symposium may easily get to Berkeley from downtown San Francisco on BART (Bay Area Rapid Transit) trains. Breakfast, lunch, and mid-morning and afternoon refreshments will be provided at the conference.
