Abstract
The present invention discloses a method for optimizing a voiceprint recognition system, a terminal device, and a computer-readable storage medium. The method comprises: obtaining a target sample corresponding to a target object identified by the voiceprint recognition system to be optimized based on a preset recognition threshold; generating a flux corresponding to the target object based on the target sample; spatially perturbing the flux and conducting a deception attack on the voiceprint recognition system based on the perturbed flux; and optimizing the voiceprint recognition system based on the perturbed flux when the deception is successful. By constructing the flux and directly optimizing the voiceprint recognition system based on the flux, the optimization time of the voiceprint recognition system is reduced and the optimization efficiency of the voiceprint recognition system is improved.
