That's good news; I haven't messed about with building emacspeak (my
speech server had been used for another project). Which build file
did you use (I think the main build target tries to build the linux
based speech servers as well)?
I dug into emacspeak sources a bit and seems fairly easy to get it all
working. It looks like you just need to modify dtk-speak.el to be
aware of the mac os server. Looks like the lisp layer communicates
with the server via (process-send-string ) which sends the string to
the process using stdin.
The way to go imo for efficiency is to write the server is native
objective c and link against appkit directly.
