The difficulty of listening to speech in noise is exacerbated when the speech is in the listener's L2 rather than L1. In this study, Spanish and Dutch users of English as an L2 identified American English consonants in a constant intervocalic context. Their performance was compared with that of L1 (British English) listeners, under quiet conditions and when the speech was masked by speech from another talker or by noise. Masking affected performance more for the Spanish listeners than for the L1 listeners, but not for the Dutch listeners, whose performance was worse than the L1 case to about the same degree in all conditions. There were, however, large differences in the pattern of results across individual consonants, which were consistent with differences in how consonants are identified in the respective L1s.
