- 30 - LPC WORD RECOGNIZER UTILIZING ENERGY FEATURES Abstract In a speech recognition arrangement, a plurality of reference templates are stored. Each template comprises a time frame sequence of feature signals of a prescribed reference pattern. A time frame sequence of feature signals representative of an unknown speech pattern is produced. Responsive to the feature signals of the speech pattern and the reference pattern templates, a set of signals representative of the similarity between the speech pattern and the reference templates is formed. The speech pattern is identified as the one of the reference patterns responsive to the similarity signals. The similarity signal generation includes producing a plurality of signals for each frame of the speech pattern, each signal being representative of the correspondence of predetermined type speech pattern features and the same predetermined type features of the reference pattern. The similarity signal for the template is formed responsive to the plurality of predetermined type correspondence signals.
