摘要:
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.

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.

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.

An idle address controller for a shared buffer type ATM switch controls the addresses of output cells in a common memory to be stored directly in an idle address buffer without passing through the conventional idle address delay controller, by improving the idle address control scheme of a unit switch. The idle address controller includes an idle address control signal generator for generating idle address control signals based on the buffer length information from counters, idle address control signal buffers for storing the idle address control signals, and an idle address control signal multiplexer. Therefore, the idle addresses can be efficiently provided, and this mechanism lowers cell loss and reduces required memory capacity.

Provided are an apparatus and method for speech segment detection, and a system for speech recognition. The apparatus is equipped with a sound receiver and an image receiver and includes: a lip motion signal detector for detecting a motion region from image frames output from the image receiver, applying lip motion image feature information to the detected motion region, and detecting a lip motion signal; and a speech segment detector for detecting a speech segment using sound frames output from the sound receiver and the lip motion signal detected from the lip motion signal detector. Since lip motion image information is checked in a speech segment detection process, it is possible to prevent dynamic noise from being misrecognized as speech.

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.
