Abstract
An apparatus for correcting errors in speech recognition is provided. The apparatus includes a feature vector extracting unit extracting feature vectors from a received speech. A speech recognizing unit recognizes the received speech as a word sequence on the basis of the extracted feature vectors. A phoneme weighted finite state transducer (WFST)-based converting unit converts the recognized word sequence recognized by the speech recognizing unit into a phoneme WFST. A speech recognition error correcting unit corrects errors in the converted phoneme WFST. The speech recognition error correcting unit includes a WFST synthesizing unit modeling a phoneme WFST transferred from the phoneme WFST-based converting unit as pronunciation variation on the basis of a Kullback-Leibler (KL) distance matrix.
