Adaptive-avg-pooling based Attention Vision Transformer for Face Anti-spoofing
Jichen Yang, Fangfan Chen, Rohan Kumar Das +2
Traditional vision transformer consists of two parts: transformer encoder and multi-layer perception (MLP). The former plays the role of feature learning to obtain better represent…
Key-Sparse Transformer for Multimodal Speech Emotion Recognition
Weidong Chen, Xiaofeng Xing, Xiangmin Xu +2
Speech emotion recognition is a challenging research topic that plays a critical role in human-computer interaction. Multimodal inputs further improve the performance as more emoti…
Data Augmentation with Signal Companding for Detection of Logical Access Attacks
Rohan Kumar Das, Jichen Yang, Haizhou Li
The recent advances in voice conversion (VC) and text-to-speech (TTS) make it possible to produce natural sounding speech that poses threat to automatic speaker verification (ASV)…
HLT-NUS Submission for NIST 2019 Multimedia Speaker Recognition Evaluation
Rohan Kumar Das, Ruijie Tao, Jichen Yang +3
This work describes the speaker verification system developed by Human Language Technology Laboratory, National University of Singapore (HLT-NUS) for 2019 NIST Multimedia Speaker R…
Light Convolutional Neural Network with Feature Genuinization for Detection of Synthetic Speech Attacks
Zhenzong Wu, Rohan Kumar Das, Jichen Yang +1
Modern text-to-speech (TTS) and voice conversion (VC) systems produce natural sounding speech that questions the security of automatic speaker verification (ASV). This makes detect…
Multi-modal Attention for Speech Emotion Recognition
Zexu Pan, Zhaojie Luo, Jichen Yang +1
Emotion represents an essential aspect of human speech that is manifested in speech prosody. Speech, visual, and textual cues are complementary in human communication. In this pape…
