Classification: CPC G | IPC G

Claim 10:
11. A computer-implemented method for spoofing countermeasures, the method comprising:
obtaining, by a computer, a plurality of training audio signals including one or more clean audio signals and one or more simulated audio signals;
training, by the computer, a neural network architecture to extract a spoofprint embedding from an audio signal and classify the audio signal, the neural network architecture trained by applying the neural network architecture on a plurality of features including one or more types of spoofing artifacts of the plurality of training audio signals, the spoofprint embedding exclusive of a voiceprint embedding;
extracting, by the computer, an inbound spoofprint for the inbound speaker by applying the neural network architecture on the plurality of features including the one or more types of spoofing artifacts of an inbound audio signal, the inbound spoofprint exclusive of an inbound voiceprint of the inbound speaker;
generating, by the computer, a spoof classification for the inbound audio signal based upon applying the neural network architecture on the inbound spoofprint, exclusive of the inbound voiceprint; and
generating, by the computer, a speaker identification for the inbound audio signal based upon applying the neural network architecture on the inbound voiceprint, the speaker identification exclusive of the spoof classification.
