20100268533 | APPARATUS AND METHOD FOR DETECTING SPEECH - 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. | 10-21-2010 |
20110071789 | Real-time motion recognition system and method - 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. | 03-24-2011 |
20120035935 | APPARATUS AND METHOD FOR RECOGNIZING VOICE COMMAND - 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. | 02-09-2012 |
20120075178 | APPARATUS AND METHOD FOR GENERATING DYNAMIC RESPONSE - A dynamic response generating apparatus and method that may analyze an intention of a user based on user input information received from an inputting device, may analyze at least one of first response information with respect to the analyzed intention of the user, context information associated with the user input information, user motion information, and environmental information, may dynamically determine a modality with respect to the first response information, may process the first response information, and may dynamically generate second response information in a form of via the determined modality. | 03-29-2012 |
20120095766 | SPEECH RECOGNITION APPARATUS AND METHOD - 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. | 04-19-2012 |
20120173244 | APPARATUS AND METHOD FOR VOICE COMMAND RECOGNITION BASED ON A COMBINATION OF DIALOG MODELS - 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. | 07-05-2012 |
20120278066 | COMMUNICATION INTERFACE APPARATUS AND METHOD FOR MULTI-USER AND SYSTEM - 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. | 11-01-2012 |
20140118248 | REAL-TIME MOTION RECOGNITION SYSTEM AND METHOD - 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. | 05-01-2014 |
