Detecting ha.e speech a.toma.ica.ly in socia. media.forensics ha. emerged a. a.highly cha.lenging ta.k due tothe complex na.ure of la.gua.e used in such pla.forms.

The work suggested in this pa.er uses a.combina.ion of the Wha.e Optimiza.ion a.gorithm(WOa. a.d Pa.ticle Swa.m Optimiza.ion (PSO) to a.just the weights of two multi-La.er Perceptron (mLPs)for neutrosophic sets cla.sifica.ion.

One mLPis dedica.ed to predicting degrees of truth membership, while the other mLP focuses on predicting degrees offa.se membership.
