Offtopic, but from the article:<p>"'When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow.' This sentence includes every sound in the English language."<p>I see immediately it seems to lack the "oo" of food, so I don't think that's quite right. I would be very interested to see what an actual sentence is that does have all the sounds.
Can we please keep these fact-free pseudoscience articles off HN? Particularly those lacking a link to the original source or even the title of the paper.

It ought to be fascinating to find out if such vocal characteristics changes over time with upper body strength in the same person (for instance, putting them through a six month strength training program). Or if this is somehow set at puberty, and people's relative strength remained the same over most of their lives. I would imagine most people don't suddenly acquire an urge to become stronger after they reach their thirties. Or at least they didn't while humans were evolving.
If conveying that information in your voice is useful, it's also very useful to be able to fake it. I lifted weights in high school, went wakeboarding with people and (briefly) went to an MMA gym. I've met skinny people with deep voices and ripped people with high voices and vice versa. I wasn't able to find a link to the original study, but I think they're completely wrong, and the correlation is nonexistent or negligible.
Margaret Thatcher had voice training to make her sound more authoritive.
Here are 2 clips the first from 1975 and the second from 1987.
They don't sound a whole lot different to me

Men's voices tend to deepen over time. Almost thirty years later, I remember the simply awful sound of the Beach Boys (upper 30s? early 40s?) trying to sing in the keys they used at 20. Could the middle-aged BBs have thrashed the twenty-something BBs?<p>(No, I didn't pay for a concert ticket--they were on the radio from the Mall on 4th of July.)
How does the research quantify "Fighting Ability" (hand-eye, violent nature, inherent strength)?
Does muscle development through intense training change the voice?
Awesome. A journal article authored by people who don't know how to fight, summarized by a person who doesn't know how to fight <i>or</i> do basic science.
