Abstract
The disclosed computer-implemented method for detecting illegitimate voice calls may include (1) identifying an incoming voice call, (2) processing the incoming voice call in real time by (a) segmenting the incoming voice call into progressively produced call segments and, (b) for each new segment as the progressively produced call segments are produced, (A) extracting a set of features from the new segment and (B) feeding, as input into a neural network, the set of features and an output from the neural network generated based on a preceding segment of the incoming voice call, thereby generating a new output representing the current likelihood that the incoming voice call is illegitimate, (3) determining that the likelihood that the incoming voice call is illegitimate is above a predetermined threshold, and (4) performing a security action during the incoming voice call. Various other methods, systems, and computer-readable media are also disclosed.
