Resumen
Abstract
This article presents the results obtained using adaptive
digital filter FIR to compensate the spectral components of the
human voice signal attenuated to be acquired in experiments that
simulate amplification devices for people with oral
communication difficulties. The signals used are human voice
recordings taken at the level of the throat in young subjects as a
reference signal and a voice signal acquired from the same
subject at the mouth. The results obtained show that the
adaptation process provides a set of coefficients that are the basis
for designing FIR digital filter with the ability to make the voice
signal level of the throat and compensate for attenuated
components.
