The present invention facilitates the change of a voice password in the vocal print authentication. A vocal print authentication system includes voice recording means for recording vocal print data of single elements of numbers and/or letters which constitute a password and vocal print data of link elements which links the respective single elements for every registrant, password forming means for forming a random password using the respective elements, vocal data forming means for forming vocal data of the password which is formed by the password forming means using the vocal print data, and password determination means for determining whether a determination requesting person is the registrant or not based on the collation between vocal data which is obtained due to the inputting by voice of the password by the determination requesting person and the vocal data which is formed by the vocal data forming means. In place of registering the voice password per se which is obtained by uttering the password, the vocal print data of the respective elements which constitute the password are registered.
