Assignee: PINDROP SECURITY, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 13:
14. A system comprising:
a non-transitory machine readable memory; and
a computer comprising a processor configured to:
generate 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 for the enrollee;

store the enrollee spoofprint into the memory;
apply a neural network architecture to an inbound audio signal, the neural network architecture trained to detect spoofing artifacts occurring in an audio signal;
generate an inbound spoofprint for an inbound speaker by applying the neural network architecture to an inbound audio signal for the inbound speaker, the inbound spoofprint exclusive of an inbound voiceprint for the inbound speaker;
generate 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
generate 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.
