Abstract

A voice recognition/response system comprising an utterance recognition unit, a dialog control processing unit, an utterance feature analyzing unit and a response voice generating unit. The utterance recognition unit recognizes utterance content of a user through a voice input therefrom and outputs recognition results. The dialog control processing unit controls progress of dialog with the user based on the recognition results so as to determine response content to the user. The utterance feature analyzing unit analyzes utterance features of the user to generate utterance feature information. The response voice generating unit generates response voice to the user based on the response content and the utterance feature information.

Claims

1. A voice recognition/response system comprising:

an utterance recognition unit for recognizing utterance content of a user through a voice input therefrom and outputting recognition results;

a dialog control processing unit for controlling progress of dialog with the user based on said recognition results so as to determine response content to said user;

an utterance feature analyzing unit for analyzing utterance features of said user to generate utterance feature information; and

a response voice generating unit for generating response voice to said user based on said response content and said utterance feature information.

2. The system as claimed in claim 1, wherein:

said utterance feature information includes a plurality of utterance feature categories, which are obtained by classifying the utterance features of the user into a plurality of groups, said utterance feature analyzing unit selecting an utterance feature category from said plurality of utterance feature categories based on said recognition results to output said utterance feature category.

3. The system as claimed in claim 2, wherein:

said plurality of utterance feature categories include parameters concerning regionality of said user.

4. The system as claimed in claim 2, wherein:

said utterance feature analyzing unit comprises;

a database for storing the utterance feature parameters, which are utilized to select said utterance feature category associated with utterance of said user; and

a device for selecting said utterance feature category, utilizing the utterance feature parameters corresponding to said recognition results.

5. The system as claimed in claim 3, wherein:

said utterance feature analyzing unit comprises;

a database for storing the utterance feature parameters, which are utilized to select said utterance feature category associated with utterance of said user; and

a device for selecting said utterance feature category, utilizing the utterance feature parameters corresponding to said recognition results.

6. A storage medium on which a voice recognition/response program to be executed by a computer is stored, wherein said program causes said computer to function as:

an utterance recognition unit for recognizing utterance content of a user through a voice input therefrom and outputting recognition results;

a dialog control processing unit for controlling progress of dialog with the user based on said recognition results so as to determine response content to said user;

an utterance feature analyzing unit for analyzing utterance features of said user to generate utterance feature information; and

a response voice generating unit for generating response voice to said user based on said response content and said utterance feature information.

7. A voice recognition/response program to be executed by a computer, wherein said program causes said computer to function as:

an utterance recognition unit for recognizing utterance content of a user through a voice input therefrom and outputting recognition results;

a dialog control processing unit for controlling progress of dialog with the user based on said recognition results so as to determine response content to said user;

an utterance feature analyzing unit for analyzing utterance features of said user to generate utterance feature information; and

a response voice generating unit for generating response voice to said user based on said response content and said utterance feature information.
