Abstract: A method of updating speech recognition data including a language model used for speech recognition, the method including obtaining language data including at least one word; detecting a word that does not exist in the language model from among the at least one word; obtaining at least one phoneme sequence regarding the detected word; obtaining components constituting the at least one phoneme sequence by dividing the at least one phoneme sequence into predetermined unit components; determining information regarding probabilities that the respective components constituting each of the at least one phoneme sequence appear during speech recognition; and updating the language model based on the determined probability information.

Abstract: A communication interface apparatus for a system and a plurality of users is provided. The communication interface apparatus for the system and the plurality of users includes a first process unit configured to receive voice information and face information from at least one user, and determine whether the received voice information is voice information of at least one registered user based on user models corresponding to the respective received voice information and face information; a second process unit configured to receive the face information, and determine whether the at least one user's attention is on the system based on the received face information; and a third process unit configured to receive the voice information, analyze the received voice information, and determine whether the received voice information is substantially meaningful to the system based on a dialog model that represents conversation flow on a situation basis.

Abstract: Provided herein is a voice recognition server and a control method thereof, the method including determining an index value for each of a plurality of training texts; setting a group for each of the plurality of training texts based on the index values of the plurality of training texts, and matching a function corresponding to each group and storing the matched results; in response to receiving a user's uttered voice from a user terminal apparatus, determining an index value from the received uttered voice; and searching a group corresponding to the index value determined from the received uttered voice, and performing the function corresponding to the uttered voice, thereby providing a voice recognition result of a variety of user's uttered voices suitable to the user's intentions.

Abstract: A method of obtaining a grammar model to perform speech recognition includes obtaining information about a state of at least one device, obtaining grammar model information about the at least one device based on the obtained information, and generating a grammar model to perform the speech recognition based on the obtained grammar model information.

Abstract: An apparatus and method for recognizing a voice command for use in an interactive voice user interface are provided. The apparatus includes a command intention belief generation unit that is configured to recognize a first voice command and that may generate one or more command intention beliefs for the first voice command. The apparatus also includes a command intention belief update unit that is configured to update each of the command intention beliefs based on a system response to the first voice command and a second voice commands. The apparatus also includes a command intention belief selection unit that is configured to select one of the updated command intention beliefs for the first voice command. The apparatus also includes an operation signal output unit that is configured to select a final command intention from the selected updated command intention belief and to output an operation signal based on the selected final command intention.

Abstract: A system and method that may sense and recognize a motion of a user is provided. The system and method may recognize a variety of motions of the user based on sensing data received from a remote controller.

Abstract: Provided are a voice command recognition apparatus and method capable of figuring out the intention of a voice command input through a voice dialog interface, by combining a rule based dialog model and a statistical dialog model rule. The voice command recognition apparatus includes a command intention determining unit configured to correct an error in recognizing a voice command of a user, and an application processing unit configured to check whether the final command intention determined in the command intention determining unit comprises the input factors for execution of an application.

Abstract: A speech detection apparatus and method are provided. The speech detection apparatus and method determine whether a frame is speech or not using feature information extracted from an input signal. The speech detection apparatus may estimate a situation related to an input frame and determine which feature information is required for speech detection for the input frame in the estimated situation. The speech detection apparatus may detect a speech signal using dynamic feature information that may be more suitable to the situation of a particular frame, instead of using the same feature information for each and every frame.

Abstract: A speech recognition apparatus is provided. The speech recognition apparatus includes a primary speech recognition unit configured to perform speech recognition on input speech and thus to generate word lattice information, a word string generation unit configured to generate one or more word strings based on the word lattice information, a language model score calculation unit configured to calculate bidirectional language model scores of the generated word strings selectively using forward and backward language models for each of words in each of the generated word strings, and a sentence output unit configured to output one or more of the generated word strings with high scores as results of the speech recognition of the input speech based on the calculated bidirectional language model scores.

Abstract: An avatar facial expression representation technology is provided. The avatar facial expression representation technology estimates changes in emotion and emphasis in a user's voice from vocal information, and changes in mouth shape of the user from pronunciation information of the voice. The avatar facial expression technology tracks a user's facial movements and changes in facial expression from image information and may represent avatar facial expressions based on the result of the these operations. Accordingly, the avatar facial expressions can be obtained which are similar to actual facial expressions of the user.
