In this paper we describe Bliss2003, an Information and Communication Technology (ICT) aid for verbal impaired people supporting the use of Augmentative and Alternative Communication (AAC) languages. Bliss2003 allows to compose messages in Bliss and other AAC languages (i.e. PCS, PIC, etc.), to translate them in natural language, to send and receive them via email, or to vocally synthetize them. Bliss2003 is characterized by a predictive module that allows for a more efficient selection of graphical symbols and more natural sessions of communication by adapting a model of the user language behavior.
