Desenvolvimento de um aplicativo móvel para treinamento em detecção de características subjetivas da voz

Abstract

This work seeks to develop an application for mobile devices, based on the Android platform, to assist in the training of future professionals in the fields of speech therapy and otorhinolaryngology. For this purpose we propose the use of a bank with thirty voices previously classified in predominance of three types of subjective characteristics: roughness, breathiness and tension. It will also make use of the Android Studio software using Java programming language and XML markup language to develop such an application. This work resulted in a tool that provides a reproducer of vocal samples and four comparison methods for auditory - perceptual characteristics and degree of vocal deviation. This didactic tool allows the user to listen, compare and classify samples according to their perceptual evaluation. Finally, the application proved to be feasible when performing its function proving to be an excellent tool for training and possible future work.
