Different voices

What makes someone sound sexy? To get a scientific viewpoint, researchers [gauged:waved] volunteers' responses to different voices. The conclusion: voices considered attractive send [messages:information] about body size. The work is in the journal PLoS ONE.In the animal kingdom, sound indicates size and intentions. For example, a rough and low-frequency call [suggests:examines] the vocalizer is large and aggressive, while a clearer, higher frequency signals a small, nonthreatening animal.In the study, researchers adjusted a variety of voices to [correspond:coordinate] with different body sizes. To do so, they synthesized completely artificial voices, and recorded sentences before varying the pitches and resonance.When volunteers listened to the sound samples, men preferred higher-pitched female voices like this one, which suggest a smaller body size. Low-frequency male voices that signalled a large body size were attractive to [females:women] .
