The MultiCo multimodal corpus is one of the outcomes of the project "Digital Research Infrastructure for the Humanities and Arts Studies DARIAH-PL." This project was funded by POIR 4.2 of the European Regional Development Fund from 2021 to 2023 and was carried out by a consortium of academic institutions across Poland with Adam Mickiewicz University, Poznan as a member of the consortium. The MultiCo multimodal corpus was developed at the Faculty of Modern Languages of Adam Mickiewicz University in Poznań. The motivation behind creating the corpus stems from contemporary research on interpersonal communication. The studies confirm that in order to understand and model the multifaceted process of communication, it's essential to study and describe not only speech but also other components of communication, such as gestures, facial expressions, and body posture. The MultiCo corpus was designed to support and facilitate this type of research approach. The corpus contains over 15 hours of recordings and consists of three sections:

• Monologs representing persuasion in parliamentary speeches and motivational talks (TEDex),
• Dialogs based on task-oriented activities recorded in a lab setting,
• Multilogs illustrating discussions with multiple participants, exemplified by conversations on current sports events (TVP Sport 4-4-2). The monolog and multilog sections are based on materials available in public media or archives, while the dialog section includes task-oriented dialogs originally designed and recorded specifically for this resource.
