To understand prosody in naturally occurring language requires an exceptional constellation of skills. One must have not only expertise in the analysis of pitch patterns and the complex signals that make up our perception of stress, but also a rich and informed perspective on how talk works. Although some phonologists are highly sophisticated in their approaches to prosody, empirical research in this area is both heavily based on laboratory-produced data (when it is empirical in that sense), and highly abstract in its descriptive procedures. For their part, analysts of spoken discourse, though basing their descriptions on naturally occurring language, often lack fundamental expertise in the close analysis of sound production and perception. The authors of Language in time are exceptional in the individual and collective skill they bring to their project. In this carefully crafted volume, Peter Auer, Elizabeth Couper-Kuhlen, and Frank Müller offer an empirically grounded and innovative view of the interplay of prosody and action in spoken language use. The volume focuses on the functions of rhythm in spoken interaction, drawing data from English, Italian, and German, and concentrating on “conversational organization and verbal performance” (p. 33). The work provides a counterbalance to the prevailing dualism in linguistic studies, by which language is first and foremost understood as a system separated from time.
