RESUMO

This work presents some results of the application?s study of Evolvable Hardware (EHW) in the area of circuits design and voice recognition. Evolvable Hardware is able to change inner connections, using genetic learning techniques, adapting its own functionality to external condition changing. This technique became feasible by the improvement of electronics devices as the Programmable Logic Devices. Nowadays, it is possible to have, in a single device, the ability to change, on-line and in real-time, part of its own circuit. This work aim to develop a reconfigurable architecture of a system that is able to receive voice commands to execute special tasks as, for instance, to help handicapped persons in their daily home routines. The idea is to collect several voice samples, process them through algorithms based on Mel - Ceptrais theory to obtain their numerical coefficients for each sample. These coefficients compose a universe of search that is used by Genetic Algorithm. The voice patterns considered, are limited to the seven sustained portuguese vowel phonemes (a, eh, e, i, oh, o, u)
