This stimulating volume is the outcome of a 1996 conference, the first in the laboratoryphonology series to incorporate psycholinguistic topics, including six chapters addressingacquisition. Here, as in the earlier conferences, the primary focus is on the relationship betweenphonetics and phonology. For example, in the first section, “Articulation and MentalRepresentation,” Munhall, Kawato, and Vatikiotis-Bateson provide a lucid account of thestate of the art in physical models of articulation; they conclude with a discussion of the difficultyof identifying the interface between phonology and speech production. In a related study, therelevance of overarching prosodic structure (“phrasal signatures”) to low-levelarticulatory effects is illustrated in some detail by Byrd, Kaun, Narayanan, and Saltzman, who findthat “prosodic structure is manifest in the details of articulation. . . . The abstract symbolicrepresentation useful to linguistics [must be integrated] with a dynamical model ofhuman movement useful to speech scientists” (p. 85).
