Speakup and pulse audio don't get along primarily because speakup is
built into the kernel as a module, meaning any speech synthesizers taht
talk to it have to be ran as root. If speakup is started before
pulseaudio starts, you'll get a situation where you get speech in the
desktop but not speech outside it. I'm not completely sure what the
cause is, but if you start espeakup, which is the espeak connector to
speakup after your desktop or pulse audio is started, it works, although
it's a little laggy. This sounds like a probme either for the speakup or
the pulseaudio people, but both deny responsibility for the problem,
urging me to bug the other, so nothing gets done. The only real
solution, if it can be called that, is to use speech-dispatcher with
speakup through a program called speechdup. But this program is long
abandoned and only works even half way in vinux, which is based off of
