MisinfoTeleGraph: Network-driven Misinformation Detection for German Telegram Messages
Lu Kalkbrenner, Veronika Solopova, Steffen Zeiler +2
Connectivity and message propagation are central, yet often underutilized, sources of information in misinformation detection -- especially on poorly moderated platforms such as Te…
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…
Unsupervised Classification of Voiced Speech and Pitch Tracking Using Forward-Backward Kalman Filtering
Benedikt Boenninghoff, Robert M. Nickel, Steffen Zeiler +1
The detection of voiced speech, the estimation of the fundamental frequency, and the tracking of pitch values over time are crucial subtasks for a variety of speech processing tech…
Multimodal Integration for Large-Vocabulary Audio-Visual Speech Recognition
Wentao Yu, Steffen Zeiler, Dorothea Kolossa
For many small- and medium-vocabulary tasks, audio-visual speech recognition can significantly improve the recognition rates compared to audio-only systems. However, there is still…
Variational Autoencoder with Embedded Student- Mixture Model for Authorship Attribution
Benedikt Boenninghoff, Steffen Zeiler, Robert M. Nickel +1
Traditional computational authorship attribution describes a classification task in a closed-set scenario. Given a finite set of candidate authors and corresponding labeled texts,…
Similarity Learning for Authorship Verification in Social Media
Benedikt Boenninghoff, Robert M. Nickel, Steffen Zeiler +1
Authorship verification tries to answer the question if two documents with unknown authors were written by the same author or not. A range of successful technical approaches has be…
Imperio: Robust Over-the-Air Adversarial Examples for Automatic Speech Recognition Systems
Lea Schönherr, Thorsten Eisenhofer, Steffen Zeiler +2
Automatic speech recognition (ASR) systems can be fooled via targeted adversarial examples, which induce the ASR to produce arbitrary transcriptions in response to altered audio si…
Adversarial Attacks Against Automatic Speech Recognition Systems via Psychoacoustic Hiding
Lea Schönherr, Katharina Kohls, Steffen Zeiler +2
Voice interfaces are becoming accepted widely as input methods for a diverse set of devices. This development is driven by rapid improvements in automatic speech recognition (ASR),…
