VIII. CONCLUSION

In this work, we investigated using the minimum knowledge of a target speaker’s speech to attack a black-box target speaker recognition model. We extensively evaluated the feasibility of using state-of-the-art VC methods to generate parrot speech samples to build a PT-surrogate model and the generation methods of PT-AEs. It is shown that PT-AEs can effectively transfer to a black-box target model and the proposed PT-AE attack has achieved higher ASRs and better perceptual quality than existing methods against both digital-line speaker recognition models and commercial smart devices in over-the-air scenarios.
