  Got a minute ?what makes someone sound sexy?don't make you ruin it . To get the scientific built point ,researchers engaged volunteers' responses to different voices,the conclusion, boys considered attractive sent messages about body size,the work is in the journal plus one,in the animal kingdom sound indicates size and intensions.for example,a rough and low frequency call suggests the vocalizer's large and aggressive ,while a clear and higher frequency signals a small and unthreatening animal.
  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 .
  Thanks for the minute for scientific American sixty-second science. I'm Sophie Bushwake.
