A New Corpus of Collaborative Dialogue Produced Under Cognitive Load Using a Driving Simulator

We present an experiment designed to collect both monologue and dialogue speech, produced under conditions that will tax the attentional resources of the speaker. Pairs of participants (native speakers of French) were asked to perform tasks involving use of the auditory memory, complex memorisation and recall, and collaborative exchange of information. Following the dual-task paradigm, we induced continuous attentional load to one of participants, using the Continuous Tracking and Reaction (ConTRe) task, in a driving simulator. In this article, we present the corpus and an initial analysis of the prosodic characteristics (silent pauses, filled pauses, disfluencies) in speech produced under cognitive load
