In this paper an augmentative and alternative communication mobile application for people with language and speech impairments, called Diga Olá, is presented. With this mobile application, we aimed to assist people with speech and language impairment in their communication process, by presenting an alternative mobile solution in Portuguese language. The main results achieved on a preliminary user assessment were: first-rate performance, higher satisfaction and total autonomy in their interaction with the solution presented.
