Abstract:

The technologies to support learning is proposed to minimize possible difficulties of students in the construction of knowledge and provides dynamic classes teachers, interactive and attractive. Therefore, technological tools should not only be an informative phenomenon, but a cognitive development tool, enabling the transformation of information and knowledge. Therefore, this work presents the development of an application questions and answers about historical characters called Ask, which uses speech recognition (questions the application) and the artificial propagation of the human voice (application plays the answers). Currently, there are several applications that use speech recognition, and others, the synthesis of speech as will be explained. Currently, there are several applications that use speech recognition, such as Google Now developed for the Android platform with the goal of helping ordinary people, showing weather forecasts, traffic and daily news of the day according to each profile. There are also applications that use artificial propagation of the human voice, like Google Translate available on the web, which in turn, reproduces words or phrases written. However, currently there is not an application that combines these two technologies (voice recognition and synthesis), especially with the educational focus. Therefore, the aim of this is to demonstrate the possibility of combining these two technologies in an application with an educational focus in order to be a tool to support interactive learning and dynamic. Therefore, the application was tested on a group of public school students aged between age 7-10 years. And, through the tests performed before and after using the application was possible to contemplate satisfactory results demonstrating the performance improvement after using the application where it was observed that the students explored the application through the questions, which led them to acquire knowledge on the historical character chosen.
