APPARATUS AND METHOD FOR GENERATING SPEECH RECOGNITION UNITS CONSIDER MORPHOLOGICAL PRONUNCIATION VARIATION

摘要

The apparatus for generating a speech recognition unit in consideration of the morpheme pronunciation variation of the present invention includes a pronunciation sequence extracting unit for extracting a pronunciation sequence of a word unit from the word unit corpus and extracting the pronunciation sequence of a pseudomorpheme unit from the pseudomorpheme unit corpus, And a pronunciation sequence alignment unit for arranging the pronunciation sequence and the pronunciation sequence of the pseudo morpheme unit, and a pronunciation sequence attaching unit that attaches the pronunciation sequence of the word unit to the pronunciation sequence of the pseudo morpheme unit to generate a corpus of the speech recognition unit. According to the present invention, by generating a speech recognition unit in which morpheme pronunciation variations are considered, the overall Korean language by reflecting variously mutated pronunciations of pseudo morphemes to the pronunciation dictionary and language model without increasing the congestion of the search network for speech recognition. There is an effect that can improve the speech recognition performance.
