Abstract
A continuous speech recognition circuit has a data generating circuit for calculating feature pattern data each having N-frame feature parameter data of a plurality of word-periods and reference pattern data every time one-frame period has elapsed and for sequentially generating a maximal similarity data among the calculated similarity data, and a recognition circuit for detecting a series of continuous word-periods which gives the largest similarity sum within a speech interval in accordance with the similarity data from the data generating circuit and recognizing as effective word data the word series corresponding to the detected series of continuous word-periods. The similarity data in each word period is obtained by calculating partial similarity data between the feature parameter data of each frame and each reference parameter data and using the N partial similarity data obtained during the word-period.
