Purpose: Conversational entrainment, also known as alignment, accommodation, convergence, and coordination, is broadly defined as similarity of communicative behavior between interlocutors. Within current literature, specific terminology, definitions, and measurement approaches are wide-ranging and highly variable. As research in this area continues to expand, particularly to fields such as speech-language pathology, consistent terminology and a means of organizing the study of entrainment is critical, affording cohesion and assimilation of knowledge. The purpose of this review article is to build upon the ideas of several researchers to create a comprehensive and systematic framework for classifying entrainment of speech behavior. Through this framework, we provide a clear and well-defined set of terminology to organize the various types of entrained behaviors and measurement approaches.Method: We begin by introducing and describing our classification framework, consisting of eight entrainment types categorized by three dichotomous classification factors: the class of entrainment (i.e., synchrony or proximity), the temporal level of entrainment (i.e., global or local), and the dynamicity of entrainment (i.e., static or dynamic). To assist with our explanations of each entrainment subtype, we draw upon rich literature of acoustic-prosodic behaviors in embodied face-face conversations and provide clear examples of each classification type.Conclusions: We conclude with a discussion of how the entrainment framework presented herein can be used to guide unified research efforts in speech-language pathology. If adopted, the framework will enable us, as a discipline, to collectively build a cohesive and informative body of literature to advance understanding of conversational entrainment in communication disorders.
