An acoustic pattern of continuous input speech is divided by an acoustic analyzer into frames of a predetermined time interval. A similarity calculator calculates similarities between frame data and the reference phonemic labels prestored in a dictionary memory, and supplies similarity data to a main processor, which has memories prestores speech duration data and connectability data. The main processor extracts, from among the references phonemic labels, those which satisfy phonetic/phonological conditions with respect to phonemes of the input speech. Similarity sum calculation is conducted only for the similarity data of the extracted labels. |
