1. A method of voice print matching which comprises: receiving a telephonic communication from an unknown caller; separating a first portion of the telephonic communication into silent and non-silent segments; evaluating the non-silent segments to determine which portions thereof are speech or non-speech; generating a plurality of parameters that determine what is speech and non-speech in the non-silent segments; using the generated parameters to determine what is speech and non-speech for at least the remainder of the telephonic communication; comparing the speech to a Universal Background Model (UBM); selecting a number of audio elements of the UBM that characterize the speech of the unknown caller relative to other audio elements of the UBM; selecting audio elements of the speech that correspond to the selected audio elements of the UBM; and comparing the selected audio elements of the speech to matching audio elements of a plurality of recorded voice prints from a plurality of fraudulent speakers to determine whether the speech belongs to a fraudulent speaker.
