Abstract:
PURPOSE: A material-distribution search method using a voice recognizing function and a method thereof are provided to search a proper transportation request by searching a distribution in the moving route in real time. CONSTITUTION: The location of a truck is traced and a truck owner selects a freight search mode through a voice(202). If the selected freight search mode is an automatic search mode, the truck owner selects the forward data search or the backward data search through a voice(203,204). If the forward data search is selected, the transportation request information after the current location is provided(205). If the backward data search is selected, the transportation request information prior to the current location is provided(206).
Abstract:
PURPOSE: A voice recognition apparatus for generating a plurality of recognition results is provided to generate N-best recognition results using a phoneme column-based search unit. CONSTITUTION: A continuous voice recognition unit(101) performs the voice recognition of input voice data. The continuous voice recognition unit outputs a word column which is most similar to the input voice data as a recognition result. A phoneme column converter(102) changes the recognition result into a phoneme column. A phoneme column-based search unit(103) searches a plurality of word columns of which a phoneme column distance is contiguity with the recognition result from a language model(105).
Abstract:
PURPOSE: A voice recognition apparatus and method having two-step utterance verification structure for reducing the complexity of N-best recognized word calculation are provided to induce the re-utterance of a user or notify the user of an utterance error. CONSTITUTION: Using a first model, a voice recognition module(130) recognizes the voice of input voice data. The voice recognition module outputs a first N-best word list. An utterance verification module(140) creates a second N-best word list. Using a second model, the utterance verification module creates a final N-best word list from the second N-best word list.
Abstract:
PURPOSE: An IPTV broadcasting system, a server and an apparatus for generating a lexicon are provided to offer a lexicon for voice recognition of the IPTV. CONSTITUTION: A pattern database(111) stores a voice generation pattern in order to offer an IPTV(Internet Protocol Television) broadcast service through the voice recognition. Using the voice generation pattern, a lexicon generating unit(110) generates a lexicon for the voice recognition corresponding to a voice command of a user. A structure information extraction unit extracts the extraction type keyword from the IPTV broadcasting information data.
Abstract:
PURPOSE: An apparatus and a method for discriminating a speech from music are provided to accurately discriminate a voice from a music for each section by configuring a complex vector value through a similarity test value. CONSTITUTION: A similarity test unit(104) tests voice or music signal similarity for an audio signal by comparing each feature vector value with a voice and music decision model value by feature vector. A complex feature vector extractor(106) constitutes the complex feature vector value based on similarity test value. A voice/music classification unit(108) discriminate a voice or music signal by section from the audio signal by comparing the corresponding voice and music discrimination model with the complex feature vector.
Abstract:
PURPOSE: A method for targeted advertisements is provided to integrate personalized advertising method using user information and contents-based customized advertising method suitable for broadcasting contents and supply hybrid-type customized advertisement to a user, thereby providing an advertisement suitable for tendency of the user in the broadcasting service environment. CONSTITUTION: According to user query input or recommended query input, a customized advertisement server provides advertisement about search query(S501,S503). A VOD(Video On Demand) server provides search result of VOD contents in a list form(S505). If a user selects main contents, the customized advertisement server provides opening advertisement(S507,S511). The VOD server shows program chapter of selected contents(S513). The customized advertisement server provides the real time advertisement(S515).
Abstract:
PURPOSE: A meta data searcher, a search method and an IPTV receiving apparatus for using the voice recognition of user uttered data by previously extracting an allomorph about a contents title are provided to search the contents which user desires by using information search functions and voice recognition. CONSTITUTION: A metadata processor(250) processes content meta data to inform data. A metadata storage unit stores content meta data. A voice recognizer(230) performs the voice recognition about firing data. A query processor(240) extracts the search word from the voice-recognized vocabulary. A search processor extracts content meta data corresponding to the search word.
Abstract:
PURPOSE: An utterance verification apparatus and a method thereof are provided, which can improve the reliability about the voice recognition result by performing the whole utterance verification about the word after the performance of the partial utterance verification about each sub word. CONSTITUTION: A sub word likelihood ratio calculator(204) calculates the sub word likelihood ratio about the divided sub word. A likelihood ratio weight applying unit(206) applies the weighted value of likelihood ratio according to the recognition reliability to the calculated sub word likelihood ratio. A word likelihood ratio calculator(208) calculates the word likelihood ratio by using the sub word likelihood ratio. A speech verification decision unit(210) decides the output of the word after the utterance verification with the calculated word likelihood ratio.
Abstract:
A voice recognition method is provided to model various textual language phenomenons into statistical modeling among various knowledge sources. A morpheme is interpreted for a primitive text language corpus consisting of the separate words of Korean(S201). A morpheme language corpus separated is a separate word generated to morpheme. A word trigram which is the language model consisting of a morpheme unigram about a generated morpheme language corpus as described above, and bigram and trigrams is generated(S202). A first N - best recognition candidate to the maximum N is generated for a voice(S204). Recognition result candidates applying a morph-syntactic constraints are revaluated(S205). A second N-best list generated in above step is revaluated(S206). A final N-best list is generated.
Abstract:
A voice recognition system and a method thereof for restoring the voice of the high quality are provided to maintain the performance of voice recognition by a voice recognition server by transmitting voice property parameter and the voice encoding parameter encoding the voice property parameter into the natural disposition. A voice property extracting part(110) outputs voice property parameter by extracting voice property parameter from voice signal inputted from a terminal(100). A voice signal part(130) outputs the terminal is encoded and the voice encoding parameter for the voice restore is outputted. A packet generating part(150) packetizes a packet including voice property parameter and voice encoding parameter. A packet transmission part inputs the packet and transmits the packet to a voice recognition server through the communications network.
