What about initializing the connection (and thus do the handshaking)
in an idle event?

http://www.pygtk.org/docs/pygobject/gobject-functions.html#function-gobject--idle-add

I guess that the speechd maintainers don't wish to add a gobject
dependency to their packages, right? If the python API exposed the
socket and a couple of functions, the caller could be responsible for
providing integration with whatever main loop it wishes to use
(gobject or qt, for example).
