Studies of vocal tension in engineering and linguistic degrees using EEG signal processing

Abstract

This work has been developed for Engineeringand Linguistic studies about signal processing algorithmsand articulatory tension of speech sounds. A educationalunit is presented related to the study of the tension generatedaround the mouth is presented. To do so, the measures of aportable EEG with 16 channels are used, which captures themuscle signals in 3 points around the mouth. Those signalsare analyzed with spectrum-temporary techniques to extractquantifiable parameters like the intensity in the tension, thefrequency in the sounds, which appear with each type ofsound or the time intervals before and after peak activitytimes. Engineering students can provide the tool with newalgorithms for the calculation of parameters, and thestudents of linguistics the characteristics of the tension in thesounds. The authors (in alphabetical order) are amultidisciplinary team.
