This paper describes the Metalogue Debate Trainee Corpus (DTC). DTC has been collected and annotated in order to facilitate the design of instructional and interactive models for Virtual Debate Coach application - an intelligent tutoring system used by young parliamentarians to train their debate skills. The training is concerned with the use of appropriate multimodal rhetorical devices in order to improve (1) the organization of arguments, (2) arguments' content selection, and (3) argument delivery techniques. DTC contains tracking data from motion and speech capturing devices and semantic annotations - dialogue acts - as defined in ISO 24617-2 and discourse relations as defined in ISO 24617-8. The corpus comes with a manual describing the data collection process, annotation activities including an overview of basic concepts and their definitions including annotation schemes and guidelines on how to apply them, tools and other resources. DTC will be released in the ELRA catalogue in second half of 2018.
