retrieving synthesized auio data?

hi Jacob and Luke

@Jacob do you need the audio data for further processing?
Or do you need only creating  wave files from the synthesized text?

Maybe a good start is to add a dummy audio output driver in speechd
which writes it's
output data into a fifo.
This wouldn't need any api work  and could  be implemented (in my
opinion) really fast and without much work!

Consider making pulse optional for ubuntu will solve this problem without
any new line code.

Luke! It's only an issue because you and other prefer the wrong audio
system. i hope one day you start thinking about other stuff to do for
speech-dispatcher than the ..... user session integration.

The decision to use pulseaudio (only) for ubuntu produced tons of mails from
many unhappy users in orca/speechd/ubuntu accessibility mailinglists.
Allmost every day some people asking howto use sd as system service etc.
BTW.: it works really well this way!

Starting paralel process and let them communicate through dbus will add
more and more and more overhead to speechd and it's deppendencies.
And it will only produce new issues without bringing really new
features instead of complexity.

Many other audio apps needs to be rewritten to be compatible with this
new approach. Thx to PA for this.

Just my two cents.

PS.: @Luke it doesn't make sense to ignore the user wishes in this area.
Read the mailinglists and talk with the people who are not able to use
pulse with speechd.
Talk also with other a11y projects and speechd users.
