Voice recognition in perioperative anesthesia – CASSANDRA supports!


An AI-based team member for perioperative anesthesia is being developed and evaluated as part of the CASSANDRA research project. The integration of speech recognition into the workflow is intended to reduce the time and mental burden on medical staff and improve the quality of documentation. In collaboration with the research partners, we are developing an AI system that understands the anaesthesia team’s dialog and documents the relevant information in real time.

We have published a video on our YouTube channel where you can get a detailed insight into our work and see how the developed solution works in practice.

For the simulation study, the actions were simulated in a simulator environment. We cordially invite you to watch the result.



The project “CASSANDRA listens and helps: An AI team member for anesthesiology” aims to improve workflows in perioperative anesthesia by providing an intelligent assistance system that supports the anesthesia team throughout the entire process. CASSANDRA listens in the background and automatically creates the documentation.

From preparation to aftercare, CASSANDRA is designed to help increase the efficiency and accuracy of patient care.

Project consortium and funding:

  • Lehrstuhl für Psychologische Ergonomie der Uni Würzburg (Projektleitung)
  • Klinik und Poliklinik für Anästhesiologie, Intensivmedizin, Notfallmedizin und Schmerztherapie am Universitätsklinikum Würzburg (UKW)
  • Prognostica GmbH

Research projects such as CASSANDRA are designed to develop innovative solutions for specific problems. In this case, the project aims to improve perioperative anesthesia through the integration of AI and speech recognition. The aim is to optimize workflows, increase efficiency and improve the quality of patient care. Research teams are working together with experts from various fields to research, develop and evaluate new technologies and concepts to ultimately have a positive impact on society.
