Speech dialogue system for facilitating improved human-computer interaction
First Claim
1. A speech dialogue system, comprising:
- speech understanding means for understanding a semantic content of an input speech from a user;
dialogue management means for making a semantic content determination of a response output according to said semantic content of said input speech understood by said speech understanding means;
response generation means for generating a speech response and a visual response according to said semantic content of said response output determined by said dialogue management means; and
output means for outputting to said user said speech response and said visual response generated by said response generation means.

Abstract
A speech dialogue system capable of realizing natural and smooth dialogue between the system and a human user, and easy maneuverability of the system. In the system, a semantic content of input speech from a user is understood and a semantic content determination of a response output is made according to the understood semantic content of the input speech. Then, a speech response and a visual response according to the determined response output are generated and outputted to the user. The dialogue between the system and the user is managed by controlling transitions between user states during which the input speech is to be entered and system states during which the system response is to be outputted. The understanding of a semantic content of input speech from a user is made by detecting keywords in the input speech, with the keywords to be detected in the input speech limited in advance, according to a state of a dialogue between the user and the system.
