1. A method comprising:
receiving, via a processor and from a user, a plurality of speech samples of a same word, wherein the plurality of speech samples of the same word comprises a current speech sample and a plurality of previously recorded speech samples;
generating, via the processor, a sample similarity from the plurality of speech samples;
making a decision, via the processor, whether to enroll the user in a speech verification system according to a comparison of the sample similarity with a threshold, wherein the decision is a first decision if the sample similarity is above the threshold and the decision is a second decision different from and mutually exclusive with the first decision if the sample similarity is below the threshold; and
enrolling the user in the speech verification system based at least in part on the decision.
