This may be partly a windoze question. I use this on a windoze box:

(defun espeak-region ()
    "Send the region to espeak"
    (shell-command-on-region (region-beginning) (region-end) "espeak -v
mb-en1 -p 50 -s 150 --stdin ")

It works, but it locks up emacs until espeak has finished reading the
text. Is there a way of spawning espeak as an autonomous process which
can finish in its own time?

See 'start-process' and 'process-send-region'.

Thanks for the suggestion. It looks as though those aren't implemented in the windoze port, but async-shell-command is. Presumably it's possible to make up an async-shell-command-on-region function from the relevent parts of simple.el.
