ABSTRACT:
A identity of a remote speaker is verified by receiving compressed audio formants from a remote Internet telephony client and comparing the compressed audio formants with sample compressed audio formants known to represent the person the remote speaker purports to be. The compressed audio formants include energy and pitch data characterizing the residue of the speaker uttering a predetermined pass phrase and a plurality of formant coefficients characterizing the resonance of the speaker.
