Software for Alternative Communication
Software for Alternative Communication
The aim of this study is evaluate a software developed for alternative communication designed
 for people with speech difficulties. The software was executed by 30 volunteers using mobile
 devices that helped to play the scenarios simulated of communication situations.
Communication is a fundamental element that contributes to the development of the human
 being, promoting their coexistence in society. However, several factors, among them the
 Cerebral palsy (CP), can cause changes in muscle tone, causing injury in phono-articulatory
 which prevent or impair the speech production. This research aims to the development of a
 mobile application to promote the augmentative and alternative communication for people with
 CP, which adapt to the characteristics of motor limitations of these users. A mobile
 application was developed with pictographic resources and a voice synthesis engine, which can
 be customized according to the level of motor impairment and need for communication of the
 user. Were recruited 30 volunteers with CP who have speech difficulties and motor impairment.
 By means of a test script, these volunteers have used the mobile application and evaluated
 their usability using the questionnaire System Usability Scale (SUS), which contains 10
 questions related to the ease of learning, efficiency, ease of memorization, occurrence of
 runtime errors of execution and level of user satisfaction.
