SOUNDBREAK: A Systematic Study of Audio-Only Adversarial Attacks on Trimodal Models
This study systematically investigates audio-only adversarial attacks on trimodal audio-video-language models, revealing significant vulnerabilities. By perturbing only the audio stream, attackers can induce severe multimodal failures, achieving up to 96% attack success. The research demonstrates that encoder-space attacks are particularly potent, often succeeding with low perceptual distortion, highlighting a critical overlooked single-modality attack surface in complex AI systems.
Executive Impact Summary
For enterprises deploying multimodal AI, this research highlights a critical, underexplored vulnerability. Audio-only perturbations can severely compromise decision-making in systems integrating sound, vision, and language. This exposes a significant risk of internal misalignment and misclassification, even with imperceptible audio manipulation, necessitating robust cross-modal consistency defenses.

SOUNDBREAK investigates untargeted, audio-only adversarial attacks on advanced trimodal AI models. The methodology systematically probes vulnerabilities across six distinct stages of multimodal processing, from raw audio encoding to high-level output likelihoods, without altering visual or textual inputs.

Incorrect Output
The study reveals that audio-only perturbations can achieve an alarming 96% attack success rate, significantly degrading multimodal reasoning. Encoder-space attacks, which target the audio encoder's representations, prove most effective, often outperforming attacks on attention mechanisms or hidden states directly.

Maximum Attack Success Rate Achieved
Crucially, effective attacks can be achieved with very low perceptual distortion, meaning the manipulated audio is often imperceptible to humans. Metrics like LPIPS remain low (e.g., 0.06), demonstrating that structured, subtle perturbations, rather than brute-force noise, are sufficient to induce catastrophic model failures. Speech recognition systems (like Whisper) are primarily sensitive to overall distortion magnitude.
| Attack Objective | ASR (%) | LPIPS (↓) | SI-SNR (dB) (↑) | Key Characteristic |
|---|---|---|---|---|
| LnegLM | 10.27 | 0.22 | -11.48 | High Distortion, Output-focused |
| L(cos) | 89.12 | 0.08 | -1.77 | Low Distortion, Encoder-focused (most effective) |
| L(audioatt) | 56.21 | 0.06 | 0.33 | Low Distortion, Attention Amplification |
| L(combined) | 96.03 | 0.14 | -6.23 | Highest ASR, Combined Effects |
This research underscores the critical need for advanced robustness strategies in enterprise AI systems, particularly those relying on multimodal inputs. The discovery of low-distortion, audio-only attack vectors means traditional anomaly detection based on signal magnitude may be insufficient. Businesses must explore defenses enforcing cross-modal consistency and potentially redesign audio processing pipelines to be less susceptible to subtle adversarial manipulations. Ignoring this attack surface could lead to compromised decision support, misinformed operations, and security breaches in critical applications.
Mitigating Subtle Audio Threats in AI
In an autonomous surveillance system relying on audio-visual cues, a subtle audio perturbation, undetectable by human ears, could lead to the misidentification of threats or misinterpretation of events. For instance, a system trained to identify 'breaking glass' might incorrectly report 'fire alarm' if a low-distortion audio attack targets its encoder. This compromises real-time decision-making and could have severe operational consequences, especially where human oversight is limited or delayed.
