An IVR signature detection and event management system facilitates real-time discovery and notification of abnormal behavior within an IVR system. The system collects metrics associated with usage of the IVR system. The system uses the collected metrics to define a baseline. Having defined a baseline, the system collects evaluation metrics for comparison to the baseline. Where the evaluation metrics deviate from the baseline beyond a threshold deviation, the system detects aberrance. The system triggers an event in response to the detected aberrance. The event may be a message, one or more corrective actions, or the like.
