Evaluating voice anonymisation using similarity rank disclosure
Shilpa Chandra, Matteo Pettenò, Nicholas Evans +7
The evaluation of voice anonymisation remains challenging. Current practice relies on automatic speaker verification metrics such as the equal error rate (EER). Performance estimat…
Lightweight Model Attribution and Detection of Synthetic Speech via Audio Residual Fingerprints
Matías Pizarro, Mike Laszkiewicz, Dorothea Kolossa +1
As speech generation technologies advance, so do risks of impersonation, misinformation, and spoofing. We present a lightweight, training-free approach for detecting synthetic spee…
Robustifying automatic speech recognition by extracting slowly varying features
Matías Pizarro, Dorothea Kolossa, Asja Fischer
In the past few years, it has been shown that deep learning systems are highly vulnerable under attacks with adversarial examples. Neural-network-based automatic speech recognition…
Federated Learning in ASR: Not as Easy as You Think
Wentao Yu, Jan Freiwald, Sören Tewes +2
With the growing availability of smart devices and cloud services, personal speech assistance systems are increasingly used on a daily basis. Most devices redirect the voice record…
Large-vocabulary Audio-visual Speech Recognition in Noisy Environments
Wentao Yu, Steffen Zeiler, Dorothea Kolossa
Audio-visual speech recognition (AVSR) can effectively and significantly improve the recognition rates of small-vocabulary systems, compared to their audio-only counterparts. For l…
Fusing information streams in end-to-end audio-visual speech recognition
Wentao Yu, Steffen Zeiler, Dorothea Kolossa
End-to-end acoustic speech recognition has quickly gained widespread popularity and shows promising results in many studies. Specifically the joint transformer/CTC model provides v…
