SPEECH RECOGNITION DEVICE, SYSTEM AND METHOD

摘要

According to a speech recognition device of the present invention, even in the case where there are many abutting sight-line detection areas or many overlapping portions between sight-line detection areas, as exemplified by the case where a plurality of icons (display objects) are congested on a display screen, it is possible to narrow down to thereby identify one icon (display object) efficiently using a sight line and a speech-based operation, and further to decrease false recognition, so that the user's convenience can be enhanced.

主权项

1. A speech recognition device which recognizes a speech spoken by a user to thereby identify from among a plurality of display objects displayed on a display device, one display object that corresponds to a recognition result, said speech recognition device comprising:
a controller to acquire the speech spoken by the user, thereby to recognize the acquired speech with reference to a speech recognition dictionary, and to output the recognition result; a sight line detector to detect a sight line of the user; a group generator to combine sight-line detection areas defined respectively for the display objects, on the basis of a sight-line detection result detected by the sight line detector, to thereby group together the display objects existing within a combined sight-line detection area having been combined; and an identifier to perform narrowing-down from the display objects grouped by the group generator, on the basis of the recognition result outputted by the controller; wherein the identifier identifies one display object from among the grouped display objects, or, when the one display object cannot be identified, re-groups the narrowed-down display objects.
