  In  the study, researchers suggested a variety of voices correspond with different body sizes. to do so, they sympasized completely artificial voices and recorded sentences before varying the pictures and resonance 1.
  when volunteers listened to the sound samples men prefer higher pitched female voices like this one, which a suggests smaller body size ,low frequency male voices that signal alarge body size ,were attractive to females.Interestingly ,breathy nice make both male and female voices more desirable.it certainly explains the enduring  popularity of happy birthday to you .
