Exploiting Neural Audio Codec Latents for Adversarial Audio Attacks

Researchers demonstrate a novel adversarial attack method against audio classification systems by operating in the latent space of neural audio codecs, achieving 99% attack success rates with extremely low inference latency (sub-7ms). This approach significantly outperforms existing generative and optimization-based attack methods, revealing critical vulnerabilities in real-time audio security systems like speaker verification.

Speaker Identity in Non-Verbal Vocalizations: Conditional Distillation and Mixture of Experts Approach

Researchers present a novel framework for speaker verification in non-verbal vocalizations (NVVs) like laughter and sighs, combining Data2Vec features with ECAPA-TDNN and a Mixture of Experts module. The approach reduces speech-to-NVV error rates from 38.93% to 22.66% while maintaining speech verification accuracy, addressing a critical gap in voice authentication systems as TTS and voice conversion technologies become increasingly sophisticated.

RAT: Reference-Augmented Training for ASV Anti-Spoofing

Researchers introduce Reference-Augmented Training (RAT), a novel approach for detecting voice spoofing and deepfakes that improves performance even when reference audio is absent during inference. The method achieves state-of-the-art results on the ASVspoof 5 benchmark, demonstrating that training with reference data induces beneficial invariance properties that enhance detection robustness.

Speaker Verification with Speech-Aware LLMs: Evaluation and Augmentation

Researchers developed a protocol to evaluate speaker verification capabilities in speech-aware large language models, finding weak performance with error rates above 20%. They introduced ECAPA-LLM, a lightweight augmentation that achieves 1.03% error rate by integrating speaker embeddings while maintaining natural language interface.
