EchoFake: A Replay-Aware Dataset for Practical Speech Deepfake Detection
Tong Zhang, Yihuan Huang, Yanzhen Ren
The growing prevalence of speech deepfakes has raised serious concerns, particularly in real-world scenarios such as telephone fraud and identity theft. While many anti-spoofing sy…
Backdoor Samples Detection Based on Perturbation Discrepancy Consistency in Pre-trained Language Models
Zuquan Peng, Jianming Fu, Lixin Zou +3
The use of unvetted third-party and internet data renders pre-trained models susceptible to backdoor attacks. Detecting backdoor samples is critical to prevent backdoor activation…
Audio-visual Event Localization on Portrait Mode Short Videos
Wuyang Liu, Yi Chai, Yongpeng Yan +1
Audio-visual event localization (AVEL) plays a critical role in multimodal scene understanding. While existing datasets for AVEL predominantly comprise landscape-oriented long vide…
PASE: Phoneme-Aware Speech Encoder to Improve Lip Sync Accuracy for Talking Head Synthesis
Yihuan Huang, Jiajun Liu, Yanzhen Ren +3
Recent talking head synthesis works typically adopt speech features extracted from large-scale pre-trained acoustic models. However, the intrinsic many-to-many relationship between…
