Actually this is being worked on. I have sent email to the
manufacturer (Access Solutions) last week about getting the specs. I'll
let you know what happens there.
I own a triple talk USB myself, so I am looking at writing the driver for it
to start with, then probably the dectalk USB.
I'll probably start with kernel level device drivers that create
a device in /devso they can be accessed from user space then figure out
how to integrate them into speakup.
Thanks,
William
