Investigating Codec-Internal Latent Audio Watermarking for Neural Codec Robustness

Zi Hu, Houmin Sun, Linxi Li +4

Neural audio codecs are challenging transformations for audio watermarking because they re-encode, quantize, and resynthesize speech. This paper investigates continuous latent-spac…

PC-Mix: Partial-Component Audio Spoofing Detection under Mixed Speech and Environmental Sound Conditions

Zhenshan Zhang, Xueping Zhang, Linxi Li +2

Recent studies on partial audio spoofing mainly focus on studio-recorded speech with temporal localization of spoofed segments. However, these studies often overlook realistic cond…

Making Separation-First Multi-Stream Audio Watermarking Feasible via Joint Training

Houmin Sun, Zi Hu, Linxi Li +4

Modern audio is created by mixing stems from different sources, raising the question: can we independently watermark each stem and recover all watermarks after separation? We study…

ESDD2: Environment-Aware Speech and Sound Deepfake Detection Challenge Evaluation Plan

Xueping Zhang, Han Yin, Yang Xiao +4

Audio recorded in real-world environments often contains a mixture of foreground speech and background environmental sounds. With rapid advances in text-to-speech, voice conversion…

MultiAPI Spoof: A Multi-API Dataset and Local-Attention Network for Speech Anti-spoofing Detection

Xueping Zhang, Zhenshan Zhang, Yechen Wang +3

Existing speech anti-spoofing benchmarks rely on a narrow set of public models, creating a substantial gap from real-world scenarios in which commercial systems employ diverse, oft…

CompSpoof: A Dataset and Joint Learning Framework for Component-Level Audio Anti-spoofing Countermeasures

Xueping Zhang, Yechen Wang, Linxi Li +2

Component-level audio Spoofing (Comp-Spoof) targets a new form of audio manipulation where only specific components of a signal, such as speech or environmental sound, are forged o…
