Over 12 months, patients at risk of relapse and healthy controls will provide weekly speech recordings and self-report data for automated analysis. Risk scores will be stored but not shared with treating clinicians. Independent clinical evaluations ensure data quality and validation. The study lays the foundation for future Clinical Decision Support System (CDSS) research and explores novel speech markers for relapse prediction while minimizing participant burden.",[27],"Psychotic Disorder","RECRUITING","2026-02-02",{"date":31,"type":32},"2026-02-09","ACTUAL",{"date":34,"type":32},"2026-01-29",{"date":36,"type":23},"2029-01-31",{"name":38,"class":39},"Philipp Homan","OTHER",7,""]
