Communication is a vital human need, its code is the language which is mainly composed by the written and the spoken channel through a set of symbols and phonemes, namely, Idiom. In this context, a person is influenced in his life by different factors to learn or train an Idiom, such as, interacting with new cultures or suffering a neuro-communicative disease. Although there exist different systems that allows language training, those approaches are designed from developers perspective leaving aside final users needs. This paper proposes a computational model based on language development theories to train idioms in context. Specifically, the design and implementation of a first module focused on the Vocabulary training is proposed and evaluated. Finally, a case study shows promising results for the model implementation.
