PROBLEM TO BE SOLVED: To provide an authentication device which secures individual confirmation and is made high in security, speedy in authentication processing, small in size and low in price. SOLUTION: In the authenticating method and authenticating device for speech recognition, an inputted keyword speech signal P is divided as an open key into a plurality of frequency regions, speech signals P1 to P4 of the plurality of divided frequency regions are selected with a 1st digital non-open key 1 having bits as many as the frequency regions, and registers as speech information 2 information whose digital non-open key number overlaps a speech signal of a selected necessary frequency region is registered as speech information 2. In authentication, the inputted keyword speech signal P is divided into the plurality of frequency regions, differences between the speech signals P1 to P4 of the plurality of frequency regions and the registered speech information 2 are calculated in the respective frequency regions, and a 2nd digital non-open key 4 corresponding to a frequency region whose signal intensity is observed is extracted and collated with the 1st digital non-open key 1 to perform authentication.
