I will have to play with that at some point. I have noticed that even
though I'm using a 16 K voice for the menus and a 16 K voice for my voice
clips, the voice clips alias a lot more. Is the voicebox script slightly
different in it's construction, from the stuff under say, Cygwin? I'm not
sure why it sounds the way it does, but I'm trying to track down the
problem.
Even when I used the same voice to make talk clips as I did for the menus
with -q 10 and -c 10, the talk clips aliased but the menu voice did not.

Oh and I forgot to mention which I should probably do in a different
thread, that I've added GigabeteF voices and Sansa E200 to my list so
that's now 8 targets.
