Voice reveals male strength

Some Santa Barbara researchers report:
Recent research has shown that humans, like many other animals, have a specialization for assessing fighting ability from visual cues. Because it is probable that the voice contains cues of strength and formidability that are not available visually, we predicted that selection has also equipped humans with the ability to estimate physical strength from the voice. We found that subjects accurately assessed upper-body strength in voices taken from eight samples across four distinct populations and language groups ...

These results provide, to our knowledge, the first direct evidence that both men and women can accurately assess men's physical strength from the voice, and suggest that estimates of strength are used to assess fighting ability.
You would think that voice would depend on innate factors, and would not have anything to do with how much time you spend pumping iron in the gym. I have noticed that there seem to be some correlations between voices and occupations, and between voices and personality types. Maybe that will get tested next.
