ABSTRACT:
A speaker recognition system for recognizing a speaker from an input voice using a neural network, in which a feature quantity extracted from the input voice is timewise averaged to create an input pattern to the neural network. The averaging technique is such that the input voice is equally divided timewise into a plurality of blocks in a simple manner and that such feature quantity is averaged every block. The feature quantity includes a frequency characteristic, pitch frequency, linear prediction coefficient, and partial self-correlation (PARCOR) coefficient of the voice.
