DIALOGUE SYSTEM AND DIALOGUE METHOD THEREOF
First Claim
1. A dialogue system, comprising:
- a multimodal input unit receiving speech and non-speech information of a user;
a domain reasoner, which stores a plurality of pre-stored situations, each of which is formed by a combination one or more speech and non-speech information, calculating an adaptability of each of the pre-stored situations based on a comparison with a situation generated based on the speech and the non-speech information received from the multimodal input unit, and determining a current domain according to the calculated adaptability of each of the pre-stored situations;
a dialogue manager selecting a response corresponding to the current domain; and
a multimodal output unit outputting the response.

Abstract
A dialogue system and a method for the same are disclosed. The dialogue system includes a multimodal input unit receiving speech and non-speech information of a user, a domain reasoner, which stores a plurality of pre-stored situations, each of which is formed by a combination one or more speech and non-speech information, calculating each adaptability of the pre-stored situations on the basis of a generated situation based on the speech and the non-speech information received from the multimodal input unit, and determining a current domain according to the calculated adaptability, a dialogue manager to select a response corresponding to the current domain, and a multimodal output unit to output the response. The dialogue system performs domain reasoning using a situation including information combinations reflected in the domain reasoning process, current information, and a speech recognition result, and reduces the size of a dialogue search space while increasing domain reasoning accuracy.

12. A dialogue system, comprising:
-
a multimodal input unit receiving speech and non-speech information of a user; a domain reasoner, which stores a plurality of pre-stored situations, each of which is formed by a combination one or more speech and non-speech information, selecting a candidate domain corresponding to a speech signal received from the multimodal input unit, calculating an adaptability of each of the pre-stored situations based on a comparison of a situation generated based on the non-speech information received from the multimodal input unit, and determining a current domain based on one of the pre-stored situations having the highest adaptability in relation to the generated situation, and the candidate domain; a dialogue manager selecting a response corresponding to the current domain; and a multimodal output unit outputting the selected response. - View Dependent Claims (13)

-
receiving speech information and non-speech information from a user; calculating an adaptability of each of pre-stored situations based on a comparison to a generated situation based on the received speech and non-speech information; determining a current domain based on the calculated adaptability; and selecting a response corresponding to the determined current domain and outputting the selected response. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
