Subject: need help with callback
To: GTK Devel List <gtk-app-devel-list gnome org>
i hope you can help me get the largest function to print
[via fprintf() --to a voiceconfile file-- the
1) gender [M or F]
2) pitch
3) speed [of speech in words/minute]
4) volume [0 -- 200%]
5) delay [in 10th of a sec between words
originalyy, i thought coding this would be trivial. it may
well be, but if so, i haven't figured it out!
this code will be on my options dropdown. please see
http://www.thought.org/vbc for my latest pix. --this is
entirely raw and unpolished; there are no links besides my
.signature.
the reason i am asking help is that my shoulder is giving
out and i don't want to press my luck. also because i am
still hard in Learn mode with gtk ... so this is one for you
gurus.
thanks for insights..
appended: dDemo.
