Language learning is a complex task and to be successful, it involves a range of cognitive processes. Intelligent Computer Assisted Language Learning systems can be useful for enhancing the effectiveness and efficiency of both teacher-led instruction and student learning. Digital technologies are routinely employed for commonly taught languages but are less frequently used in the Less Commonly Taught Language (LCTL) context. In this study, we investigate methods for encouraging the learning and teaching of LCTLs, particularly indigenous and endangered languages. Our research blends language learning pedagogy, socio-cultural theory, and Digital Game-Based Language learning (DGBLL) in the form of games and Virtual Reality. Language learning materials are enhanced with the aid of Natural Language Processing techniques. We present a DGBLL system designed to promote language learning and student engagement. The system has been tested successfully in primary school classrooms, with positive feedback from both students and teachers.
