Replay attacks are the simplest and the most easily accessible form of spoofing attacks on
voice biometric systems and can be hard to detect by systems designed to identify spoofing …

Chances are that most of us have experienced difficulty in listening to our interlocutor during
face-to-face conversation while in highly noisy environments, such as next to heavy traffic or …

We present a system that associates faces with voices in a video by fusing information from
the audio and visual signals. The thesis underlying our work is that an extreme simple …

Audio-visual synchronization aims to determine whether the mouth movements and speech
in the video are synchronized. VocaLiST reaches state-of-the-art performance by …

针对现有一致性判决方法主要对整句(段) 话进行分析, 并无对分析内容加以筛选,
存在运算繁琐及结果易受静音等弱关联片段影响等不足, 以唇型变化显著的韵母发音单元为研究 …

Audiovisual speech synchrony detection is an important part of talking-face verification
systems. Prior work has primarily focused on visual features and joint-space models, while …

We address the problem of liveness detection in audiovisual recordings for preventing
spoofing attacks in biometric authentication systems. We assume that liveness is detected …

Speech and speaker recognition systems are integrated into our everyday life; voice
assistants answer questions, set timers, or play music, but also send personal messages …

Audiovisual speech synchrony detection is an important part of talking-face verification
systems. Prior work has primarily focused on visual features and joint-space models, while …

The ability to employ automatic speaker verification systems without face-to-face contact
makes them more prone to malicious spoofing attacks compared to most other biometric …
