Claim 0:
1. A computer-implemented method for spoofing countermeasures, the method comprising:
generating, by a computer, an enrollee spoofprint for an enrollee based upon a first set of one or more features extracted from one or more enrollee audio signals for the enrollee, wherein the first set of one or more features includes one or more types of spoofing artifacts of the enrollee, the enrollee spoofprint exclusive of an enrollee voiceprint of the enrollee;
applying, by the computer, a neural network architecture to an inbound audio signal, the neural network architecture trained to detect spoofing artifacts occurring in an audio signal;
generating, by the computer, an inbound spoofprint for an inbound speaker by applying the neural network architecture to the inbound audio signal for the inbound speaker, the inbound spoofprint exclusive of an inbound voiceprint of the inbound speaker;
generating, by the computer, a voice similarity score based upon one or more similarities between the inbound voiceprint and the enrollee voiceprint to compare against an enrollee voice match threshold; and
generating, by the computer, a spoof likelihood score for the inbound audio signal based upon one or more similarities between the inbound spoofprint and the enrollee spoofprint to compare against a spoof detection threshold separate from the enrollee voice match threshold.
