[orca-list] Speech is stuttering since Feisty update

[hermann <steppenwolf2 onlinehome de>]

Hi,
since I've updated my system to Feisty, I observe a strange stuttering
of the speech. It ocurs anywhere e.g. in no special program and for no
obvious reason. It is also not reproducable or predictable. 
I use Feisty with the very latest Orca and the very latest Espeak with
Gnome speech driver.
Any ideas?
Hermann
