20080212932 | SYSTEM FOR MANAGING VIDEO BASED ON TOPIC AND METHOD USING THE SAME AND METHOD FOR SEARCHING VIDEO BASED ON TOPIC - A video management method and system based on a topic, and a video search method based on a topic. The video management system includes: a video topic management unit extracting a topic from information associated with a video, storing the extracted topic, and monitoring the video associated with the stored topic; a video storage management unit storing the video and information associated with the video, and managing a storage space based on the topic which is stored in the video topic management unit; and a topic video management unit generating a topic video of the monitored video when the video associated with the stored topic is monitored, and providing a search function and a navigation function of the video which is stored in the video storage management unit. | 09-04-2008 |
20090055179 | Method, medium and apparatus for providing mobile voice web service - Provided are a method and apparatus for providing a mobile voice web service in a mobile terminal. The method includes analyzing a web history of a user from web search logs of the user and generating a voice access list based on the analysis results, and performing voice recognition by dynamically generating a voice recognition syntax according to the generated voice access list. Accordingly, by limiting syntax required for voice recognition by generating a syntax suitable for a web context of the user, efficient voice recognition, which can be performed in a terminal not a server, can be implemented. | 02-26-2009 |
20090157383 | VOICE QUERY EXTENSION METHOD AND SYSTEM - A voice query extension method and system. The voice query extension method includes: detecting voice activity of a user from an input signal and extracting a feature vector from the voice activity; converting the feature vector into at least one phoneme sequence and generating the at least one phoneme sequence; matching the at least one phoneme sequence with words registered in a dictionary, extracting a string of the matched words with a linguistic meaning, and selecting the string of the matched words as a query; determining whether the query is in a predetermined first language, and when the query is not in the first language as a result of the determining, converting the query using a phoneme to grapheme rule, and generating a query in the first language; and searching using the query in the first language. | 06-18-2009 |
20090157398 | Method and apparatus for detecting noise - A method of and apparatus for detecting noise are provided. The method of detecting noise includes: receiving an input of a voice frame and converting the voice frame into a filter bank vector; converting the converted filter bank vector into band data; calculating a weight Gaussian mixture model (GMM) for each band by using the converted band data; and detecting noise in the voice frame based on the calculation result. | 06-18-2009 |
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 |
20100277579 | APPARATUS AND METHOD FOR DETECTING VOICE BASED ON MOTION INFORMATION - Disclosed are an apparatus and method of deducing a user's intention using motion information. The user's intention deduction apparatus includes a speech intention determining unit configured to predict a speech intention regarding a user's speech using motion information sensed by at least one motion capture sensor, and a controller configured to control operation of detecting a voice section from a received sound signal based on the predicted speech intention. | 11-04-2010 |
20100280983 | APPARATUS AND METHOD FOR PREDICTING USER'S INTENTION BASED ON MULTIMODAL INFORMATION - Disclosed are an apparatus and method of deducing a user's intention using multimodal information. The user's intention deduction apparatus includes a first predictor to predict a part of a user's intention using at least one piece of motion information, and a second predictor to predict the user's intention using the predicted part of the user's intention and multimodal information received from at least one multimodal sensor. | 11-04-2010 |
20100286987 | APPARATUS AND METHOD FOR GENERATING AVATAR BASED VIDEO MESSAGE - An apparatus and method for generating an avatar based video message are provided. The apparatus and method are capable of generating an avatar based video message based on speech of a user. The avatar based video message apparatus and method displays information that corresponds to input user speech. The avatar based video message apparatus and method edits the input user speech according to a user input signal with reference to the displayed information, generates avatar animation according to the edited speech, and generates an avatar based video message based on the edited speech and the avatar animation. | 11-11-2010 |
