TS-SP: Learning Speaker-Preserving Representations in Audio Large Language Models

Junjie Li, Zheng Liang, Zhe Li +2

Audio large language models (ALLMs) can understand speech content, yet their ability to use speaker identity for verification remains limited. We propose TS-SP (Two-Stage Speaker P…

Addressing Gradient Misalignment in Data-Augmented Training for Robust Speech Deepfake Detection

Duc-Tuan Truong, Tianchi Liu, Junjie Li +3

In speech deepfake detection (SDD), data augmentation (DA) is commonly used to improve model generalization across varied speech conditions and spoofing attacks. However, during tr…

QAMO: Quality-aware Multi-centroid One-class Learning For Speech Deepfake Detection

Duc-Tuan Truong, Tianchi Liu, Ruijie Tao +3

Recent work shows that one-class learning can detect unseen deepfake attacks by modeling a compact distribution of bona fide speech around a single centroid. However, the single-ce…
