Pulseaudio latency problem

[Hammer Attila]

Dear list,

Sorry if my letter with possible little offtopic with this list rule, 
but my problem related with Ubuntu and Speech-dispatcher. I hope any 
people possible help me.
I read the pulseaudio latency wiky document, I think this is fantastic 
with future if I understand right the document.
So, my problem:
I downloaded the current Ubuntu Karmic dayly live cd. Pulseaudio is 
enabled again with accessible profile, this is not problem because works 
again my volume control button my notebook. The problem is 
speech-dispatcher produce very disturb latency when pulseaudio is 
running my soundcard (3-4 sec) with speech parts all time. I am using 
Orca Screen Reader. How can I fix this problem, or this is future fixing 
problem with next versions of Speech-dispatcher and Ubuntu?
lspci says following output my sound card:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio 
Controller (rev 03)

If my e-mail is offtopic, sorry every body.
