  • Patent number: 6560576
    Abstract: A voice-enabled application, which may be a voice browser, is configured to provide active help to a user. The application maintains a usage history of each user with respect to dialog states. The usage history includes various user-specific variables, some of which are valid across multiple sessions. The application maintains a number of active help prompts capable of being played to a user as speech, each containing information on a different, specific help topic. The application further maintains a number of sets of conditions, each set corresponding to a different one of the active help prompts. The application monitors dialog states during a session of a user and generates an event based on the dialog states. The application applies certain ones of the conditions to certain ones of the user-specific variables in response to the event. The application then plays a active help prompt containing information on a specific help topic to the user if the applied conditions are satisfied.
