This paper presents CA²JU, a hardware/software tool that aims to help individuals with severe speech or language problems in their communication in order to promote their social and digital inclusion. CA²JU is composed of two applications: CA²JU Accelerated, which makes typing faster by suggesting potential words to the user; and CA²JU Illustrated, which automatically converts a sentence of words into a sequence of pictographic symbols, allowing a user familiar with the symbols to verify whether the written sentence is correct. We have implemented, evaluated in a controlled scenario, and deployed CA²JU in a real environment with children with cerebral palsy. In the controlled settings, the results confirm CA²JU Accelerated speed up typing by reducing the number of clicks made by users, and CA²JU Illustrated obtained high accuracy by suggesting the correct pictograms from sentences. In the real scenario, the two use cases show that the children improved their communication and linguistic abilities.
