Valued by employers in our globalized societies, plurilingual communication skills are essential for international mobility. It is therefore vital to develop pedagogical techniques that encourage the acquisition of linguistic and cultural skills, since future job candidates who possess these will be more successful in professional networking. As we boldly venture into the Fourth Industrial Revolution (FIR), the job market is evolving rapidly and the integration of Artificial Intelligence (AI) continues in our private and professional lives. Consequently, the job market is even more competitive and many job candidates may perhaps one day require career conversions. Accelerated language learning, with diagnostic assessment and evaluation through human and machine interaction could serve as a potential solution. Two decades of Information Technology (IT) development have yielded a plethora of pedagogic language tools and resources; however, some argue that these tools remain tedious, limited, dispersed or partitioned. In contrast, AI offers a single entry point into a world of technological opportunities for impartial language assessment and diagnostic evaluation. This presentation proposes to briefly explain how a three-year dictogloss study with third-year Psychology students evolved into an innovative transversal project which focuses on human interaction with AI, in order to yield standardized diagnostic assessments through real-time personalized training of individual language learners.
