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.
