• A laboratory training study was conducted in order to investigate the effect of context on identification of English words minimally contrasting in /r/-/l/, /b/-/v/, or /s/-/θ/. Thirty native speakers of Japanese participated in a word identification task and perceptual training under the three stimulus conditions: (1) WD condition (words in isolation), (2) NS condition (words within a semantically neutral carrier sentence), and (3) CS condition (words within a semantically contextual carrier sentence). Identification performance for /r/-/l/ and /b/-/v/ during test phases showed that the accuracy differed significantly between the stimulus condition in the order, NS < WD < CS. This tendency was not significant for the /s/-/θ/ contrast, which showed the highest identification score among the three contrasts. These results suggest that semantic context raised identification accuracy while acoustic context lowered it when the target phonemes were difficult to identify. Furthermore, in case of /r/-/l/, it was shown that training with the CS stimuli improved the accuracy for stimuli in CS condition but not for those in other conditions. This result together with the above results implies that when language learners are provided with meaningful information during training, they are likely to learn the strategy to exploit semantic cues. Thus, perception training based on auditory input is revealed to be important in order to develop robust listening comprehension ability.
