for file in *.mp3 ; do
	file="${file/%.mp3/}"
	say -fo "${file}.tmp" -a "$file"
	lame "${file}.tmp" -o "${file}.talk"
	rm "${file}.tmp";
done

I expect its something to do with quoting all the file names, but I
can't tell exactly what it might be for any particular files. I fixed a
few little problems that were the result of dashing that off under the
influence of too much coffee, but there seems to be some problem with
the say command where it won't write the text I give to it with the -a
option to the file specified by -fo. Alas the closed source nature of
say prevents me from figuring it out easily. The solution probably
involves writing all the file names to temporary text files and then
passing them to say using the -fi option. I'll fiddle with it a little
more and let you know if I get a good one working as this just seems
like its a cool idea to get working and it should be pretty easy once I
get all the cob webs out of my head regarding shell scripting.
