METHOD AND APPARATUS FOR LEXICAL DECODING

摘要

A vocabulary decoding method and an apparatus thereof are provided to shorten overall performance time of voice recognition without deteriorating voice recognition performance. Based on an inputted voice signal, length of a phoneme series which is outputted by decoding phonemes is detected. Based on the detected length of the phoneme series, recognition target words(202) similar to the length of the phoneme series are selected. Edition distance measurement with the phoneme series is carried out on the basis of the selected recognition target words. Through the edition distance measurement, at least one recognition target word having a minimum edition distance with the phoneme series is outputted.
