Abstract

Currently all technological progress should go in search of satisfying a need of society, in all contexts: health, work, study, etc. in this article we plan a prototype bracelet in the field of assistive technologies specifically for deaf or hearing loss people. the development of this prototype is able to discriminate sounds an alert or emergency, in addition to managing a user Interface quite friendly with additional features like Clock, alarm, among others. For the process of discrimination of sounds and alert detection system was used as a training tool, the Artificial Neural Networks (ANN). Was implemented for the microcontroller DSPIC33EP512GP502 microcontrollers. Previous tests demonstrate greater efficiency of 75% in identifying three types of sounds of emergency (ambulance, police, fire).
