METHOD FOR DIALOG MANAGEMENT
First Claim
1. A system for communicating with a user via a spoken dialog service, the system comprising:
- a module configured to select a dialog motivator from a plurality of dialog motivators based at least in part on user input, the plurality of dialog motivators including an assumption dialog motivator and a confirmation dialog motivator; and
a module configured, when the spoken dialog system requests further user input and invokes the confirmation dialog motivator to confirm the further user input, to;
receive the further user input; and
if a confidence value associated with understanding the further user input is below a threshold value, invoke the assumption dialog motivator to present assumed further user input during a confirmation dialog.

Abstract
A spoken dialog system and method having a dialog management module are disclosed. The dialog management module includes a plurality of dialog motivators for handling various operations during a spoken dialog. The dialog motivators comprise an error handling, disambiguation, assumption, confirmation, missing information, and continuation. The spoken dialog system uses the assumption dialog motivator in either a-priori or a-posteriori modes. A-priori assumption is based on predefined requirements for the call flow and a-posteriori assumption can work with the confirmation dialog motivator to assume the content of received user input and confirm received user input.

12. A system for communicating between a user and a spoken dialog service using an assumption dialog motivator associated with a dialog management module, the system comprising:
-
a module configured to create constructs CC, CI, and CT; a module configured to invoke a missing information dialog motivator to request first user input comprising user identification information; a module configured, according to the first user input, to update construct CC and CI a module configured, if the spoken dialog service has low confidence in the first user input, to invoke a confirmation dialog motivator and update CC, CI, and CT; a module configured, if a first user confirmation response to a first confirmation dialog is negative, to; update CC; and invoke the missing information dialog motivator to request second user input comprising user identification information; a module configured to receive the second user input and update CC and CI accordingly; a module configured, if the spoken dialog service has a low confidence in the second user input, to invoke the confirmation dialog motivator and update CC, CI and CT; and a module configured, if a second user confirmation response to a second confirmation dialog is positive, to invoke the assumption dialog motivator and update CC and CI accordingly. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
