Man-machine dialogue system, controls dialogue between system and user using dialogue specification employing augmented transition networks propagating tokens
First Claim
1. A man-machine dialogue system comprising an interactive computer system with:
- an input device for receiving speech input from a user;
an output device for generating output to a user;
an object system which is an information source or store, or a command and control device, the object of the dialogue being to interface between this system and a user, wherein the object system further comprises knowledge sources to assist recognition;
a dialogue manager, which controls the dialogue between the object system and a user comprising;
a dialogue specification applied to the speech input from the user during recognition comprising;
a set of augmented transition networks (ATNs), having a set of states, wherein each state is one of a question/answer cycle, data processing, a simple junction, and a sub-dialogue state;
one or more tokens propagated through the states, each token comprising a set of fields which together define a current state of belief of a dialogue controller, dependent upon the preceding user-system interchanges and information obtained from the object system.

Abstract
A man-machine dialogue system employing an interactive computer system comprising an input device for receiving input from the user. An output device generating output to the user. There is provided an object system which is an information source or store, or a command and control device. The system has a dialogue manager, which orchestrates the dialogue between the object system and user dependent upon a dialogue specification. The specification employs a set of augmented transition networks (ATNs), through which are propagated one or more tokens, the token comprising a set of fields which together define the current state of belief of the dialogue controller, dependent upon the preceding user-system interchanges and information obtained from the object system.

15. A system comprising:
- an output device for generating output to a user;
an input device for receiving input from a user; a tool for generating an object system which is an information source or store, or a command and control device, the object of the dialogue being to interface between the system and the user; and a dialogue manager, which controls the dialogue between the object system and the user based upon;
a dialogue specification, comprising a set of augmented transition networks (ATNs), having a set of states through which are propagated one or more tokens, wherein each state is one of a question/answer cycle, data processing, a simple Junction, and a sub-dialog state, and wherein each token comprises a set of fields which together define a current state of belief of a dialogue controller, dependent upon the preceding user-system interchanges and information obtained from the object system.
- an output device for generating output to a user;
-
16. A method for controlling dialogue between a computer system and a human user comprising the steps of:
-
outputting at least one speech signal to the user; inputting a speech signal from the user in response to each of the at least one speech signal output to the user; propagating at least one token over a set of augmented transition networks comprising a set of states, wherein each state is one of a question/answer cycle, data processing, a simple junction, and a sub-dialogue state, wherein propagating comprises; applying a dialogue specification to the speech signal input from the user; and updating the at least one token over the set of augmented transition networks, each token comprising a set of fields which together define a current state of belief of a dialogue controller, dependent upon the preceding user-system interchanges and information obtained from the object system. - View Dependent Claims (17, 18)

19. A computer-readable medium including instructions readable by a computer which, when implemented perform steps comprising:
-
generating a speech-based output to the user; receiving a speech-based input from the user in response to the generated speech-based output; propagating at least one token over a set of augmented transition networks, wherein propagating comprises; applying a dialogue specification to the speech signal input from the user; and updating the at least one token over the set of augmented transition networks comprising a set of states, wherein each state is one of a question/answer cycle, data processing, a simple junction, and a sub-dialogue state, and wherein each token comprises a set of fields which together define a current state of belief of a dialogue controller, dependent upon the preceding user-system interchanges and information obtained from the object system. - View Dependent Claims (20)
