i think you have it nailed! [g]vim creates a .SWAP file in
the pwd; so since gvim creates .talk.N.txt.swp while the
textfile is being types into, i do a while(!done) check on
the .swap file. then i do a second while loop while
talk.N.txt exists. finally, espeak [flags] | aplay speaks
the words in the text file. [ i tee the output of espeak
and hand it off to aplay because of strange driver bugs here
on my desktop.]

thanks much. i'll check g_spawn_async() to see how it is
used. i hadn't thought of any of the flavors of wait;
everything has worked: gvim//write-quit/espeak a dozen
times.
but the gtk app is greyed and the quit button doesn't work!
