Patent ID: 8417525

Claim:
A computer-implemented method of updating voice prints over time, the computer-implemented method comprising: receiving, by a processor, an initial voice print; calculating, by the processor, a determining period of time, wherein the determining period of time is a length of time during which an expected degree of change is predicted to occur in comparison to the initial voice print; receiving, by the processor, a new voice print after the determining period of time; comparing, by the processor, the new voice print with the initial voice print; in response to a change to the new voice print falling within the expected degree of change in comparison to the initial voice print, updating, by the processor, a voice print store with the new voice print; and in response to a predefined extended period of time passing between receiving the initial voice print and the new voice print, updating the voice print store with the new voice print, wherein the predefined extended period of time is an extended period of time during which the change to the new voice print is predicted to fall outside the expected degree of change in comparison to the initial voice print.
