Beyond Waveform Robustness: Robust Feature-Vocoder Adversarial Attacks on Automatic Speech Recognition
Researchers have developed a new adversarial attack method against automatic speech recognition systems that operates in feature space rather than directly on audio waveforms, achieving significantly higher transfer rates to black-box ASR models and bypassing existing defenses. The attack uses self-supervised learning representations and vocoders to reconstruct adversarial signals, revealing critical vulnerabilities in current ASR robustness evaluation protocols.
