It is to provide a speaker verifying apparatus and the like capable of updating the identifier of a registering speaker at a low cost, considering that voices change over time. An update data generating apparatus comprises functions of: inputting registering speaker's voice feature value data to the speaker identifier of the registering speaker to obtain hypothesis scores, and generating a registering speaker score vector string constituted with a plurality of vectors having the hypothesis scores as the elements; inputting background speaker's voice feature value data to the speaker identifier of the registering speaker to obtain hypothesis scores, and generating a background speaker score vector string constituted with a plurality of vectors having the hypothesis scores as the elements; and storing the registering speaker score vector string and the background speaker score vector string to a storage device.
