Temporal cycles in speech production

Abstract: The term macroplanning has been used to refer to the construction of semantic-conceptual structures that enable speakers to accomplish communicative goals during spontaneous speech production. One form of evidence provided as support for the existence of macroplanning are temporal cycles in speech fluency. The assumption is that speakers alternate between phases of low fluency, during which they prepare macroplans, and high fluency, during which macroplans are executed in speech. Existing models of macroplanning suggest that temporal cycles therefore reflect a scheduling problem between processes competing for the capacity of shared resources. Time series analyses confirmed the existence of temporal cycles in spontaneous spoken discourse. In addition, evidence that topic shifts generally precede periods of increasing fluency in the temporal cycle was thought to be consistent with the assumption that the cycle reflects macroplanning activity. Existing models of macroplanning are reviewed in light of these results, and problems associated with the underlying assumptions of these models are discussed.
