Perceptual learning alters effects of foreign language backgrounds in speech-in-speech recognition.

The effect of training on linguistic release from masking (LRM) was examined. In a pre-test and post-test, English monolingual listeners transcribed sentences presented with English and Dutch maskers. During training, participants transcribed sentences with either Dutch, English, or white noise maskers and received feedback. LRM was evident in the pre-test (performance was better with Dutch maskers) but was eliminated after training (masker conditions did not differ). Thus, the informational masking driving LRM can be ameliorated through training. This study is a basis for future research examining the specific aspects of informational masking that change as a function of experience.
