摘要
The present invention relates to an apparatus and method for recognizing Korean continuous speech and an automatic interpretation system using the same, using a conventional simple grammar as a forward search method and adopting a dependent syntax that expresses Korean grammar features well with a backward search method. Feature extraction means (11) for extracting features of an input speech to provide a speech recognition apparatus and method and an automatic interpretation system using the same; Word modeling means 15 for modeling words; Word recognition means (12) for recognizing speech on a word-by-word basis; Sentence recognizing means (13) for recognizing a sentence using a bigram 18 as a forward-looking language model; And sentence recognizing means (14) using the dependent grammar (19) as a backward language model, comprising: a first step (31, 32) of determining whether it is the last frame after initialization; A second step (33, 34) of performing a language processing process by applying a forward language model after performing Viterbi calculation on the input speech every frame unit; and backward language model every word unit from the last frame. A continuous speech recognition means (41, 42) comprising a third step (35) of applying the grammar and using the dependent grammar as a backward language model; Storage means 43 for storing parsing results analyzed by the backward language model; Conversion and generating means 44 for converting and generating a result of parsing into a sentence of another language; And a speech synthesis means 45 for synthesizing and outputting the translated speech, thereby improving continuous speech recognition rate, and having an economic effect by reducing interpretation time and simplifying the system.
