Voice cloning tech repurposed for anonymization, raising security concerns

By PulseAugur Editorial · [2 sources] ·

Researchers have found a way to repurpose the XTTSv2 voice cloning model for speaker anonymization without retraining. This model, trained on extensive speech data, can preserve prosodic structure independently of speaker identity, allowing for voice conversion by conditioning on a pseudo-speaker. An iterative refinement strategy balances privacy and utility, achieving high privacy and intelligibility with superior speech quality compared to existing anonymization methods across seven European languages. AI

IMPACT This research demonstrates a dual-use capability of voice cloning models, highlighting potential privacy benefits and new avenues for social engineering scams.
