Method of and apparatus for managing dialog between user and agent
First Claim
1. A method of managing a dialog turn between a user and a spoken dialog system, the method comprising:
- generating first dialog turn information using dialog information analyzed from a speech uttered by the user;
generating second dialog turn information using facial expression information analyzed from a face image of the user;
selecting one of the first and second dialog turn information using predetermined weight information; and
determining a final dialog turn using the selected one dialog turn information, information on a status of the spoken dialog system, information on whether the user speech is input, and information on a no-answer time of the user, for controlling a dialog between the user and the spoken dialog system.

Abstract
A method of rapidly and precisely managing a dialog turn between a user and an agent by using speech information, facial expression information, and delay time information includes generating first dialog turn information using dialog information analyzed from a speech uttered by the user, generating second dialog turn information using facial expression information analyzed from a face image of the user, and determining a final dialog turn using the first and second dialog turn information, information on a status of the spoken dialog system, information on whether the user speech is input, and information on a no-answer time of the user.

10. An apparatus for managing a dialog turn between a user and a spoken dialog system, the apparatus comprising:
-
a dialog analyzer that generates first dialog turn information using dialog information analyzed from a speech uttered by the user;
a facial expression analyzer that generates second dialog turn information using facial expression information analyzed from a face image of the user;

15. A spoken dialog system comprising:
-
a speech input unit that amplifies a user speech input via a microphone to a predetermined level;
a speech recognizer that recognizes the speech signal provided by the speech input unit to output a character string signal;
an image input unit that inputs a user face image;
a timer counts a user no-answer time for a predetermined period of time;
a dialog manager that generates first dialog turn information using dialog information analyzed from the character string signal, generates second dialog turn information using facial expression information analyzed from the user face image, and determines a final dialog turn using the first and second dialog turn information, information on a status of the spoken dialog system, the character string signal, and the user no-answer time; and
an answer generator that generates an answer corresponding to the character string signal with reference to a dialog model database according to a control operation of the dialog manager.

-
generating first dialog turn information using dialog information analyzed from a speech uttered by the user;
generating second dialog turn information using body expression information analyzed from a detected body expression of the user;
selecting one of the first and second dialog turn information using predetermined weight information; and
determining a final dialog turn using the selected one dialog turn information for controlling a dialog between the user and the spoken dialog system. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
