A new research paper published on arXiv details a corrected protocol for evaluating the hackability of speech quality metrics. The study identifies flaws in existing measurement methods, such as attributing the perturbation effects of neural codecs to the attack itself and relying on a single trained attacker. Using the proposed protocol, the researchers found significant differences in hackability among four published predictors, with NISQA being the most vulnerable and UTMOS the least. The paper also examines a closed attack-detect-patch loop, concluding that it offers limited hardening and is less effective than a random-perturbation baseline. AI
