Whisperish

Hey there,

a few weeks ago or so people were talking about whispering, and voiceless
vowels and other normally voiced sounds.
i was thinking about that one day after my sociolinguistics class, and
came up with an idea for a language:

phonemically, the language has only voiceless phonemes, for instance:
/ p t c k P f T s S C x H W J a* e* i* o* u* /  ~ ( /*/ = devoiced ; / W
J / = voiceless [ w j ] )

However, under certain conditions, everything becomes voiced:
[ b d c^ g B v D z Z C^ G 3 w j a e i o u ]  ~ ( /^/ = voiced )

What kind of conditions could those be?
someone mentioned a word /qqs/ in a native american language whose
speakers were unable to shout it.  maybe shouting would voice the sounds?
or, on a more sociolinguistic note, maybe there's a split between
men/women, familiar/formal, etc., that would determine whether there's
voice or not.
