Contributing to the current discussion of how the grammar of spoken language use can be theorized, the present volume focuses on the following questions: Should prosodic and visual resources such as gesture, gaze etc. be considered part of such an interactional grammar? If so, how may these aspects of language use be incorporated? Seeking to complement findings from studies informed with an interactional approach, the volume further asks whether the modeling of an interactional grammar may benefit from instrumental approaches and annotated corpora.
