Cepstral Analysis of Sexually Appealing Voice
The results of cepstral analysis in sexually attractive voices revealed higher values of CPP in comparison to the voices rated as sexually not appealing. This could be because of the presence of well-defined harmonic structure evidenced in the sexually appealing voice in comparison to voices rated as very unappealing. Our findings suggest that cepstral analysis is a good indicator of sexually appealing voice.
