Kudos and much gratitude to all who work on this! Here's the way Karmic
is supposed to run.

Hi, David. I rewrote the pulseaudio driver for speech-dispatcher,
based on work by some other folks with a libao driver. It does get
rid of the long delay. The easiest way to get the patch is probably
to add the Vinux/Ubuntu Karmic repository to your sources.list file,
and then to apt-get upgrade. Note that if you use ibmtts, you'll need
to install those files as well from the repository. To use the
repository, as root, edit /etc/apt/sources.list, and add these lines
at the bottom:
deb http://ppa.launchpad.net/vinux/vinux-karmic/ubuntu karmic main
deb-src http://ppa.launchpad.net/vinux/vinux-karmic/ubuntu karmic main
Next, you want to tell your system not to complain about unsigned
packages when installing. To do this, import the key from Ubuntu
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EF2AFDCF
Then, do the usual apt-get commands:
$ sudo apt-get update
$ sudo apt-get upgrade
That should update speech-dispatcher and espeak. If you use speakup
and speechd-up, then the speechd-up package will be updated as well,
so that it can run as a service on boot.
Base on e-mails I read from Luke, it seems likely that Lucid will ship
with a new pulseaudio driver based on this work, and should have much
better performance. I hope to release a Vinux/Ubuntu Lucid ISO
shortly afterwards, probably in May, which has these improvements and
