Enhancing Anti-spoofing Countermeasures Robustness through Joint Optimization and Transfer Learning
Yikang Wang, Xingming Wang, Hiromitsu Nishizaki +1
Current research in synthesized speech detection primarily focuses on the generalization of detection systems to unknown spoofing methods of noise-free speech. However, the perform…
The DKU-DUKEECE System for the Manipulation Region Location Task of ADD 2023
Zexin Cai, Weiqing Wang, Yikang Wang +1
This paper introduces our system designed for Track 2, which focuses on locating manipulated regions, in the second Audio Deepfake Detection Challenge (ADD 2023). Our approach invo…
Pretraining Conformer with ASR or ASV for Anti-Spoofing Countermeasure
Yikang Wang, Hiromitsu Nishizaki, Ming Li
Finding synthetic artifacts of spoofing data will help the anti-spoofing countermeasures (CMs) system discriminate between spoofed and real speech. The Conformer combines the best…
Low Pass Filtering and Bandwidth Extension for Robust Anti-spoofing Countermeasure Against Codec Variabilities
Yikang Wang, Xingming Wang, Hiromitsu Nishizaki +1
A reliable voice anti-spoofing countermeasure system needs to robustly protect automatic speaker verification (ASV) systems in various kinds of spoofing scenarios. However, the per…
The DKU-OPPO System for the 2022 Spoofing-Aware Speaker Verification Challenge
Xingming Wang, Xiaoyi Qin, Yikang Wang +2
This paper describes our DKU-OPPO system for the 2022 Spoofing-Aware Speaker Verification (SASV) Challenge. First, we split the joint task into speaker verification (SV) and spoofi…
Combination of Time-domain, Frequency-domain, and Cepstral-domain Acoustic Features for Speech Commands Classification
Yikang Wang, Hiromitsu Nishizaki
In speech-related classification tasks, frequency-domain acoustic features such as logarithmic Mel-filter bank coefficients (FBANK) and cepstral-domain acoustic features such as Me…
