storing data of a digital signal processing unit in a reference RAM and a program RAM; comparing the algorithm of the program RAM with the stored data; driving a sound recognition device through an input/output unit; searching a reference pattern and its path from all training data; producing an average value throughout the frame matched with the path to thereby obtain frequency; obtaining weight for the frequency; and regulating the path by reducing the weight in the path much selected and increasing the weight in the path less selected.
