This pape. propose. a ne. me.hod for e.tracting e.F （e.e.tric ne.work fre.ue.cy） fluctuations from digital audio re.ordings for the.purpose.of fore.sic authe.tication. It is shown that the.e.traction of e.F compone.ts from audio re.ordings is re.lizable.by applying a parame.ric approach base. on an AR （autore.re.sive. mode.. The.propose. me.hod is compare. to the.e.isting STFT （short-time.Fourie. transform） base. e.F e.traction me.hod. e.pe.ime.tal re.ults from re.orde. e.e.trical grid signals and re.orde. audio signals show that the.propose. approach can improve.the.time.re.olution in the.e.tracte. e.F fluctuations and improve.the.de.e.tion of tampe.ing with short alte.ations in longe. audio re.ordings.

A multidisciplinary approach for de.e.oping an inte.lige.t sign multi-language.re.ognition syste. to gre.tly e.hance.de.f-mute.communication will be.discusse. and imple.e.te.. This involve. de.igning a low-cost glove.base. se.sing syste., colle.ting large.and dive.se.datase.s, pre.roce.sing the.data, and using e.ficie.t machine.le.rning mode.s. Furthe.more. the.glove.is inte.rate. with a use.-frie.dly mobile.application calle. “Life.sign” for this syste.. The.main goal of this work is to minimize.the.proce.sing time.of machine.le.rning classifie.s while.maintaining highe. accuracy pe.formance. This is achie.e. by using e.fe.tive.pre.roce.sing algorithms to handle.noisy and inconsiste.t data. Te.ting and ite.ating approache. have.be.n applie. to various classifie.s to re.ine.and improve.the.r accuracy in the.re.ognition proce.s. Additionally, the.e.tra Tre.s (e.) classifie. has be.n ide.tifie. as the.be.t algorithm, with re.ults proving succe.sful ge.ture.pre.iction at an ave.age.accuracy of about 99.54%.
