Multiple studies demonstrate that speech perception in noisy environments differs based on a listener's native language background and linguistic experience.
The retrieved literature consistently shows that speech perception in noise varies significantly depending on whether listeners are processing their native language versus a second language, or comparing monolinguals to bilinguals. Papers [1], [3], [5], and [6] directly support the claim by testing speech perception in noise across different native language groups and finding measurable variations. No papers refute the claim.
