Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, advances in deep learning have made deepfake media increasingly difficult to distinguish from genuine content. In the speech domain, remarkable progress has been achieved, including the ability to generate synthetic speech that accurately mimics specific speakers. However, the malicious use of such technologies has become a serious concern, and improving robustness against attacks using previously unseen deepfake media has emerged as an important challenge.
In this study, we propose a method for generating high-quality deepfake speech that imitates multiple real speakers by applying speech enhancement and zero-shot text-to-speech to speech obtained through non-consensual recordings containing background noise, which are generally unsuitable for training speech synthesis models. Experimental results on countermeasure systems and automatic speaker verification systems demonstrate that the speech generated by the proposed method can successfully bypass existing speech security systems with high accuracy.
