Mobile adaptive CALL (MAC): an adaptive s/w for computer assisted language learning

In this paper, we present a mobile adaptive computer-assisted language learning (MAC) software aimed to help Japanese-English speakers in perceptually distinguishing the non-native /r/ vs. /l/ English phonemic contrast with a view to improving their own English pronunciation. MAC is implemented in Java (J2ME), allowing the software to be used on a wide range of mobile devices including most recent mobile phones. This allows the application to be used anywhere and anytime, on devices that learners would commonly already own.
