Piotr is striving mightily to explain breathy-voiced and
creaky-voiced in words. What we really need, of course, are sound files. I do
know that some people on cybalist and/or phoNet have the soft/hardware to
create such files, but I don't know if they can manage this particular set of
sounds. As for the disk space to support such sounds, go to the search engines
and use the free space they offer.
The one sound I really want to hear is Czech r-hacek (r-caron),
[ř], as in the composer Dvořák's name. This
is probably the most sensational phoneme in any Indo-European
language.
My next computer, probably a cadillac from Gateway, will have all the
goodies, but presently, I don't.
Mark.
