  "title": "Psychoacoustically Aligned Latent Smoothing for Adversarial Robustness of Full-Duplex Speech-to-Speech Dialogue Models",
  "summary": "PALS replaces an undefended residual-vector-quantized latent interface in full-duplex speech-to-speech models with anisotropic Gaussian noise injection shaped by local codebook covariance, trained via a KL consistency objective, as a defense against psychoacoustically masked adversarial perturbations. It adds no inference-time cost but requires training-time access to the model's latent codebook interface and its covariance statistics, plus retraining with the consistency loss. It can fail against adaptive attackers who optimize through the smoothing noise, offers only a limited certified radius well below observed empirical robustness, and its validation is confined to a Moshi-style architecture, leaving transferability to other speech stacks unproven.",
  "rationale": "The defense requires white-box training access to a full-duplex speech model's RVQ latent interface, which is unavailable to a reader constrained to third-party APIs or a single GPU without foundation-model training, though the threat model is worth tracking if they deploy open speech agents.",
