1. A system for detecting manipulated vocal audio, comprising:
one or more processors; and
memory in communication with the one or more processors and storing instructions that, when executed by the one or more processors, are configured to cause the system to:
receive a communication comprising a first utterance of a user;
transform the first utterance from a wavelength domain to a frequency domain;
determine a divergence of one or more amplitude values of the frequency domain from a predetermined frequency distribution;
determine whether the communication is associated with a first predefined risk tier, a second predefined risk tier, or a third predefined risk tier;
when the divergence exceeds a predetermined threshold and the communication is associated with the first predefined risk tier, execute one or more first security measures;
when the divergence exceeds the predetermined threshold and the communication is associated with the second predefined risk tier, execute one or more second security measures; and
when the divergence exceeds the predetermined threshold and the communication is associated with the third predefined risk tier, execute one or more third security measures.
