  • Patent number: 10885079
    Abstract: Disclosed herein are system, method, and computer program product embodiments for providing voice-activated events management. An embodiment operates by receiving an audio-formatted query through an application associated with an event. A first user ID, registered with the event, is determined to be associated with the mobile device. It is determined whether the query is an event query or a user query based on one or more keywords. Based on the determination that the query is either the event query or the user query, the answer to the event query is determined from data retrieved over a network, or the answer to the user query is determined from the locally stored data at the mobile device. The determined answer to the query is provided via the application operating on the mobile device.
