A deep learning model for speech recognition suffers from adversarial noise. Which mechanism limits its ability to generalize from training data?

💡 Explanation

Acoustic invariance promotes over-reliance on superficial acoustic features, and adversarial noise exacerbates this. This degrades the distributional consistency because the model learns spurious correlations that do not generalize. Therefore, acoustic invariance limits robustness to novel noisy data, rather than improving feature selection or gradient stability.
