Falante: aplicativo de auxílio à fala baseado em tecnologia Android

Abstract

The inability to express a decision or a feeling, both provoked by a physical or psychological trauma, exposes the individual to personal and social impacts that sometimes may cause problems in his intellect or live in society. Thinking about this need and studying the methods currently available to this group of people, it was developed an application for tablets and smartphones which helps persons with difficulties in oral communication. Method: Collecting information with professionals who use Augmentative and Alternative Communication during their daily work, and making a deep study about the first words and sentences that are necessary when someone wants to be introduced in a new language, we created and classified a database of phrases and expressions. They were associated to the alternative communication symbols in order to be part of a communication board for cellphones and tablets running Android operational system. The application reproduces the sound corresponding to the meaning of the activated image through touch. Results: 400 images with sound make part of the system created as well as the possibility of the user to edit his own board with pictures of the collection. When Falante ́s interface and the architecture of the software used in mobile devices were presented to the volunteers, 80% of them was able to use the system after few minutes of instruction, and 90% used the application at some moment during the therapy to express needs. It proves the benefits that techniques of alternative communication in mobile devices can bring to people with communication difficulties. Conclusion: The prototype was able to reproduce efficiently the sound related to the meaning of the images, resulting in effective communication for children with speech difficulties. It was possible to observe positive emotions expressed by users when their desires and needs were understood and attended. Among the major positive feelings, we point out wellbeing, calmness and courage expressed by the users.
