Abstract
A useful, novel, and nonobvious speech verification apparatus, method and media incorporating the same, as well as a secure interactive voice response ("IVR") system. The speaker verification apparatus and method involves a determination whether one or more speech samples captured from a speaker substantially matches a speaker template in a registration database. If no substantial match is found, alternate access control is utilized to allow the speaker to verify herself, without the use of speaker verification techniques. If alternative access control is able to verify the speaker, the captured speech samples are used to modify the corresponding speaker template. The so-modified speaker template may account for acoustic idiosyncrasies or anomalies perceived in the speech samples to improve verification rates in subsequent acoustic attempts.
