Abstract

An input profile (101) is generated from an input audio file using a measurable attribute that was used to generate reference profiles (102) from reference audio files. The input profile (101) is then subjected to a process that was also used to generate a reference profiles tree (103), which is structured as a sparse binary tree, which is used by the audio matcher (100) to facilitate and expedite the matching process form the reference profiles (102). The input profile (101) is then compared with this subset of the reference profiles (102), representing potential matches, to determine that either it matches one of the reference profiles (102), or that it is a spoof, or that it does not match any of the reference profiles (102).
