Method and apparatus for recognizing speech according to dynamic display
First Claim
1. A speech recognition apparatus, comprising:
- a display device configured to display data on a screen;
a controller configured to generate a display variation signal indicating that variations have occurred on a screen, and create display information about the varied screen; and
a speech recognizer configured to adjust a word weight for at least one word related to the varied screen and a domain weight for at least one domain included in the varied screen, according to the display variation signal and the display information, and perform speech recognition using a dynamic language model in which the adjusted word weight and the adjusted domain weight are reflected,wherein the speech recognizer comprises a weight adjusting unit configured toadjust word weights and domain weights according to variations of the display information, andassign a greater domain weight to at least one domain having a greater portion overlapping a current screen and at least one domain having a shorter distance to a center of the current screen.

Abstract
A speech recognition apparatus and method that can improve speech recognition rate and recognition speed by reflecting information for dynamic display, are provided. The speech recognition apparatus generates a display variation signal indicating that variations have occurred on a screen and creates display information about the varied screen. The speech recognition apparatus adjusts a word weight for at least one word related to the varied screen and a domain weight for at least one domain included in the varied screen, according to the display variation signal and the display information. The adjusted word weight and the adjusted domain weight are dynamically reflected in a language model that is used for speech recognition.

21. A speech recognition apparatus, comprising:
-
a display device configured to display words on a screen; and a speech recognizer configured to perform speech recognition using a dynamic language model, and to dynamically adjust the dynamic language model such that words currently displayed on the screen have an increased probability of being recognized as speech when subsequently receiving an utterance from a user, wherein the speech recognizer comprises a weight adjusting unit configured to adjust word weights and domain weights according to variations of display information, and assign a greater domain weight to at least one domain having a greater portion overlapping a current screen and at least one domain having a shorter distance to a center of the current screen.
