DiffAttack: Diffusion-based Timbre-reserved Adversarial Attack in Speaker Identification
Qing Wang, Jixun Yao, Zhaokai Sun +3
Being a form of biometric identification, the security of the speaker identification (SID) system is of utmost importance. To better understand the robustness of SID systems, we ai…
Speaker Contrastive Learning for Source Speaker Tracing
Qing Wang, Hongmei Guo, Jian Kang +4
As a form of biometric authentication technology, the security of speaker verification systems is of utmost importance. However, SV systems are inherently vulnerable to various typ…
NPU-NTU System for Voice Privacy 2024 Challenge
Jixun Yao, Nikita Kuzmin, Qing Wang +6
Speaker anonymization is an effective privacy protection solution that conceals the speaker's identity while preserving the linguistic content and paralinguistic information of the…
MUSA: Multi-lingual Speaker Anonymization via Serial Disentanglement
Jixun Yao, Qing Wang, Pengcheng Guo +4
Speaker anonymization is an effective privacy protection solution designed to conceal the speaker's identity while preserving the linguistic content and para-linguistic information…
Distinctive and Natural Speaker Anonymization via Singular Value Transformation-assisted Matrix
Jixun Yao, Qing Wang, Pengcheng Guo +2
Speaker anonymization is an effective privacy protection solution that aims to conceal the speaker's identity while preserving the naturalness and distinctiveness of the original s…
Timbre-reserved Adversarial Attack in Speaker Identification
Qing Wang, Jixun Yao, Li Zhang +2
As a type of biometric identification, a speaker identification (SID) system is confronted with various kinds of attacks. The spoofing attacks typically imitate the timbre of the t…
The FlySpeech Audio-Visual Speaker Diarization System for MISP Challenge 2022
Li Zhang, Huan Zhao, Yue Li +6
This paper describes the FlySpeech speaker diarization system submitted to the second \textbf{M}ultimodal \textbf{I}nformation Based \textbf{S}peech \textbf{P}rocessing~(\textbf{MI…
Pseudo-Siamese Network based Timbre-reserved Black-box Adversarial Attack in Speaker Identification
Qing Wang, Jixun Yao, Ziqian Wang +2
In this study, we propose a timbre-reserved adversarial attack approach for speaker identification (SID) to not only exploit the weakness of the SID model but also preserve the tim…
Distance-based Weight Transfer from Near-field to Far-field Speaker Verification
Li Zhang, Qing Wang, Hongji Wang +4
The scarcity of labeled far-field speech is a constraint for training superior far-field speaker verification systems. Fine-tuning the model pre-trained on large-scale near-field s…
Distinguishable Speaker Anonymization based on Formant and Fundamental Frequency Scaling
Jixun Yao, Qing Wang, Yi Lei +4
Speech data on the Internet are proliferating exponentially because of the emergence of social media, and the sharing of such personal data raises obvious security and privacy conc…
Preserving background sound in noise-robust voice conversion via multi-task learning
Jixun Yao, Yi Lei, Qing Wang +6
Background sound is an informative form of art that is helpful in providing a more immersive experience in real-application voice conversion (VC) scenarios. However, prior research…
