Prior-Enhanced Audio LLMs (PELM)

The proposed PELM framework unifies speech editing detection and content localization using a generative formulation based on Audio LLMs. It addresses the limitations of traditional frame-level detectors, especially for deletion-type edits where manipulated content is absent.

Key components include prior-enhanced prompting, which injects word-level probabilistic cues from a frame-level detector, and an acoustic consistency-aware loss, which explicitly enforces separation between normal and anomalous acoustic representations in the latent space.

AiEdit: A Comprehensive Bilingual Benchmark

To overcome the limitations of existing datasets, we introduce AiEdit, a large-scale bilingual dataset (approx. 140 hours) covering addition, deletion, and modification operations. It is generated using state-of-the-art end-to-end speech editing systems, providing a more realistic benchmark for modern deepfake threats.

AiEdit's diverse editing patterns and inclusion of deletion operations make it uniquely suited for evaluating advanced detection models, reflecting the evolving landscape of audio manipulation.

Strengthening Acoustic Evidence

Audio LLMs, while powerful, can sometimes over-rely on semantic information, leading to predictions not sufficiently grounded in acoustic evidence. PELM mitigates this through two core mechanisms:

  • Prior-Enhanced Prompting: Word-level probabilities from a frame-level detector are injected into the prompt, guiding the LLM's acoustic reasoning.
  • Acoustic Consistency-Aware Loss: This loss function explicitly encourages discriminative feature structures in the latent space, separating normal and anomalous acoustic representations.

Safeguarding Against Modern Deepfakes

The robust performance of PELM across diverse editing types and its strong cross-domain generalization ability make it a vital tool for enterprise security. It can accurately detect and localize subtle audio manipulations that evade conventional methods, crucial for sectors like finance, media, and legal.

This technology provides a proactive defense against misinformation, impersonation, and fraudulent activities relying on sophisticated audio deepfakes.
