Spawning autonomous shell commands

[Hilary]

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

(defun espeak-region ()
"Send the region to espeak"
(interactive)
(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.

Of course, they are. What made you think they aren't?

Yes, that's another way to go.
