Voice recognition method and voice recognition apparatus
First Claim
1. A voice recognition apparatus for recognizing a voice spoken by a speaker comprising:
- a recognition dictionary which stores groups of recognition candidates respectively associated with visual target objects located around the speaker;
a sight line detector that detects a direction of a sight line of the speaker; and
a controller that;
determines one of the visual target objects located in the direction of the sight line of the speaker on the basis of the direction of the sight line;
from among the recognition candidates in the recognition dictionary, sets each of the recognition candidates associated with the determined visual target object as a recognition target range; and
from among the recognition target range, selects a recognition candidate which is highly similar to voice data inputted by a microphone.

Abstract
Systems and methods store groups of recognition candidates respectively associated with visual target objects located around a speaker. The systems and methods detect a direction of a sight line of the speaker or a movement by the speaker. The systems and methods determine one of the visual target objects on the basis of the direction of the sight line or the movement. The systems and methods set, from among the recognition candidates in the recognition dictionary, each of the recognition candidates associated with the determined visual target object as a recognition target range, and from among the recognition target range, select a recognition candidate which is highly similar to voice data inputted by a microphone.

9. A voice recognition apparatus for recognizing a voice spoken by a speaker, comprising:
-
a recognition dictionary which stores groups of recognition candidates respectively associated with visual target objects located around the speaker; a movement detector that detects a movement of the speaker; and a controller that; selects a category associated with the movement of the speaker and determines one of the visual target objects on the basis of the selected category; sets the each of the recognition candidates associated with the visual target object as a recognition target range; and from among the recognition target range, selects a recognition candidate which is highly similar to voice data inputted by a microphone. - View Dependent Claims (10, 11)

12. A voice recognition method for recognizing a voice spoken by a speaker, comprising:
-
detecting a direction of a sight line of the speaker; predicting a visual target object located in the direction of the sight line; setting each of a plurality of recognition candidates corresponding to the predicted visual target object as a recognition target range; from among the recognition target range, selecting a recognition candidate which is highly similar to the voice spoken by the speaker. - View Dependent Claims (13, 14)
