20100145680 | METHOD AND APPARATUS FOR SPEECH RECOGNITION USING DOMAIN ONTOLOGY - A speech recognition method using a domain ontology includes: constructing domain ontology DB; forming a speech recognition grammar using the formed domain ontology DB; extracting a feature vector from a speech signal; modeling the speech signal using an acoustic model. The method performs speech recognition by using the acoustic model, the speech recognition dictionary and the speech recognition grammar on the basis of the feature vector. | 06-10-2010 |
20110054883 | SPEECH UNDERSTANDING SYSTEM USING AN EXAMPLE-BASED SEMANTIC REPRESENTATION PATTERN - A speech understanding apparatus includes: a speech recognition unit for recognizing an input speech to produce a speech recognition result; a sentence analysis unit for performing morpheme analysis on a sentence corresponding to the speech recognition result, extracting additional information, and performing syntax analysis; a hierarchy describing unit for describing hierarchy of the sentence; a class transformation unit for performing class transformation on the sentence; a semantic representation determination unit for marking optional expressions for the sentence, deleting meaningless expressions and the additional information, converting the sentence into its base form, and deleting morphemic tags or symbols to determine a semantic representation; a semantic representation retrieval unit for retrieving the determined semantic representation from an example-based semantic representation pattern database; and a retrieval result processing unit for selectively producing a retrieved semantic representation. | 03-03-2011 |
20110153309 | AUTOMATIC INTERPRETATION APPARATUS AND METHOD USING UTTERANCE SIMILARITY MEASURE - Provided is an automatic interpretation apparatus including a voice recognizing unit, a language processing unit, a similarity calculating unit, a sentence translating unit, and a voice synthesizing unit. The voice recognizing unit receives a first-language voice and generates a first-language sentence through a voice recognition operation. The language processing unit extracts elements included in the first-language sentence. The similarity calculating unit compares the extracted elements with elements included in a translated sentence stored in a translated sentence database and calculates the similarity between the first-language sentence and the translated sentence on the basis of the comparison result. The sentence translating unit translates the first-language sentence into a second-language sentence with reference to the translated sentence database according to the calculated similarity. The voice synthesizing unit detects voice data corresponding to the second-language sentence and synthesizes the detected voice data to output an analog voice signal corresponding to the second-language sentence. | 06-23-2011 |
20110301936 | INTERPRETATION TERMINALS AND METHOD FOR INTERPRETATION THROUGH COMMUNICATION BETWEEN INTERPRETATION TERMINALS - A method for interpreting a dialogue between two terminals includes establishing a communication channel between interpretation terminals of two parties in response to an interpretation request; specifying a language of an initiating party and a language of the other party in each of the interpretation terminals of the two parties by exchanging information about the language of the initiating party used in the interpretation terminal of the initiating party and the language of the other party used in the interpretation terminal of the other party via the communication channel; recognizing speech uttered from the interpretation terminal of the initiating party; translating the speech recognized by the interpretation terminal of the initiating party into the language of the other party; and transmitting a sentence translated into the language of the other party to the interpretation terminal of the other party. | 12-08-2011 |
20120010873 | SENTENCE TRANSLATION APPARATUS AND METHOD - Disclosed herein are a sentence translation apparatus and method. The sentence translation apparatus includes a voice recognition unit, a morphemic part-of-speech tagging unit, a pause extraction unit, and a sentence separation unit. The voice recognition unit creates a sentence in a first language based on results of recognition of a voice in a first language. The morphemic part-of-speech tagging unit tags morphemic parts of speech from the sentence in the first language. The pause extraction unit extracts pause information from the voice in the first language. The sentence separation unit separates the sentence in the first language based on information about the morphemic parts of speech tagged by the morphemic part-of-speech tagging unit and the pause information extracted by the pause extraction unit. | 01-12-2012 |
20130103382 | METHOD AND APPARATUS FOR SEARCHING SIMILAR SENTENCES - An apparatus for searching similar sentences that has a translation sentence database includes an input unit to which a sentence is input; first language processing unit configured to perform language processing on sentences input through the input unit; and first language similarity calculating unit configured to refer to previously translated sentences to extract similar sentences for the first language sentence. Further, the apparatus includes translating unit configured to translate a sentence into a second language sentence; second language processing unit configured to perform language processing on a second language sentence; second language similarity calculating unit configured to refer to the previously translated sentences to extract similar sentences for the second language sentence; and a re-ranking unit configured to combine similar sentence extracting results of the first language with those of the second language to re-rank sentence outputs. | 04-25-2013 |
20140156256 | INTERFACE DEVICE FOR PROCESSING VOICE OF USER AND METHOD THEREOF - The present invention suggests an interface device for processing a voice of a user which efficiently outputs various information so as to allow a user to contribute to the voice recognition or the automatic interpretation and a method thereof. For this purpose, the present invention suggests an interface device for processing a voice of a user which includes an utterance input unit configured to input utterance of a user, an utterance end recognizing unit configured to recognize the end of the input utterance; and an utterance result output unit configured to output at least one of a voice recognition result, a translation result, and an interpretation result of the ended utterance. | 06-05-2014 |
20140303957 | AUTOMATIC TRANSLATION AND INTERPRETATION APPARATUS AND METHOD - The present invention relates to an automatic translation and interpretation apparatus and method. The apparatus includes a speech input unit for receiving a speech signal in a first language. A text input unit receives text in the first language. A sentence recognition unit recognizes a sentence in the first language desired to be translated by extracting speech features from the speech signal received from the speech input unit or measuring a similarity of each word of the text received from the text input unit. A translation unit translates the recognized sentence in the first language into a sentence in a second language. A speech output unit outputs uttered sound of the translated sentence in the second language in speech. A text output unit converts the uttered sound of the translated sentence in the second language into text transcribed in the first language and outputs the text. | 10-09-2014 |
20150066472 | METHOD AND APPARATUS FOR GENERATING MULTIPLE PHONEME STRINGS FOR FOREIGN NOUN - A method for generating multiple phoneme for foreign proper nouns according to the present invention comprises: converting a second language proper noun uttered in a first language to a second language word using an automatic translator; generating second language phoneme strings corresponding to the second language word using a second language G2P; converting the second language phoneme strings to first language phoneme strings; generating first language phoneme strings corresponding to the second language proper noun uttered in the first language using a first language G2P; and generating a plurality of phoneme strings by using the first language phoneme strings obtained through the step of converting to the first language phoneme strings and the first language phoneme strings obtained through the step of generating the first language phoneme strings. | 03-05-2015 |
