This demo aims to bring a closer view of all the free-distribution tools gathered in “Comunica” (http://www.vocaliza.es). “Comunica” is set, initially, to provide speech therapy to children with special needs during their processes of language acquisition in Spanish. The three tools (“PreLingua”, “Vocaliza” and “Cuéntame”) cover different levels of language, from phonation and articulation to linguistic and descriptive abilities. The demo is focused on the more recent advances in “Comunica” presented at the SLaTE workshop: A novel tool for the training of the Spanish vowels with on-line formant normalization and a new version of “Vocaliza”, with phoneme-level evaluation and feedback, oriented to young children who approach Spanish as a second language.
