Abstract
A computer system that classifies audio content is described. During operation, the computer system may receive audio content. Then, the computer system may determine a representation of the audio content (such as a signal-processing representation) by performing a transformation on the audio content. In some embodiments, the transformation may include a neural network and/or the representation may include word embedding or sense embedding of words in the audio content. Moreover, the computer system may analyze the representation using a predetermined neural network. Next, the computer system may classify, based at least in part on an output of the predetermined neural network, the audio content as being fake or real, where the fake audio content is, at least in part, computer-generated. Furthermore, the computer system may selectively perform a remedial action based at least in part on the classification.
