Compensation for voice-producing devices for people with oral communication difficulties

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.
