Use of Voice Synthesis and Voice Recognition mechanisms for the development of applications on mobile-cellular devices

Abstract

The article presents an analysis of the design and architecture used in the development of a system, built on the Android platform, that enables communication through text messages (SMS) via voice commands. The system implements actions such as reading, receiving, deleting, and writing SMS messages. The goal is to allow users to keep their hands and eyes free so they can perform other daily activities such as driving, exercising, cooking, etc. The functionality is based on the creation of a context-free grammar, which allowed for the generation of a finite language for users to interact with their phones using voice commands. To incorporate this functionality, a software platform was used that operates on mobile devices—specifically cell phones—and allows access to native services such as sending and receiving SMS, as well as the integration of third-party technologies, thus enabling the unification of various features and solutions. The system can be used by anyone with basic knowledge of how mobile-cellular technologies running on Android work, and whose vocal system is in good condition to issue the voice commands that control the system.
