Has nothing to do with the vocal tone:
I've never smoked, but neither has my voice ever been confused with that of a female.
The tonality of your voice IS something you can change, within a range, and it's apparent that the denigration of the American male has had the effect of making males afraid to sound like men.
Note the distinction I make between "male" and "man."
To use a foreign example, the current actor portraying James Bond (and rather forgettably, too, or I'd be able to think of his name!) is male;
Sean Connery, OTOH, is a man.
I find it interesting that most tough guys lately are not Americans.
Daniel Craig (the current Bond, and you are being a little harsh on him. I have found him to be excellent in everything he does.)
Jason Statham
Gerard Butler
Clive Owen
Hugh Jackman
At the same time, they have all branched out in some very non-masculine movies. Butler follows up 300 with P.S. I Love You, Jackman did The Boy From Oz after X-Men, between King Arthur and Sin City, Owen did Closer.
I take that back Statham hasn’t branched out. Unless you count cartoony action as opposed to a more traditional action movie branching out.
