Abstract:
A system for controlling access to a resource comprising:means for storing a reference voice sample of an authorized user of said resource;means for obtaining a ""dirty"" voice sample from a person seeking access to said resource;means for applying a voice recognition process to said dirty and reference voice samples, to derive an indication therefrom of the extent of mismatch between said samples;means for setting a variable mismatch limit related specifically to conditions pertaining to allowable uses of said resource;means for determining if said derived mismatch indication exceeds said related mismatch limit; a determination that said derived mismatch indication exceeds said related mismatch limit being considered indicative that the person seeking access is probably not said authorized user associated with said reference voice sample, and a determination that said derived mismatch indication does not exceed said related mismatch limit being considered indicative that the person seeking access could be said authorized user;means for utilizing said determination that said derived mismatch indication does not exceed said related mismatch limit for permitting said person seeking access to said resource to have access to said resource; andmeans for utilizing said determination that said derived mismatch indication exceeds said related mismatch limit for initiating further action to control access to said resource by said person seeking access to said resource.
