Native and non-native listeners’ perception of Thai and English final stops were examined in two experiments.
Listeners demonstrated distinct response patterns of results according to their L1.
While it is not possible to conclude
that bilinguals’ L1 perception has remained intact after an extensive exposure to L2, the results obtained in this study are interpreted as suggesting that L2 learning does not impact negatively on one’s L1 perception system.
In this study, overall results averaged across different contrasts (CDT) and places of articulation (identificationtest) were presented.
Discrimination accuracy of each of the three contrasts tested (i.e., /p/-/t/, /p/-/k/, /t/-/k/) and identification patterns of each place of articulation are currently being analyzed
