[orca-list] Delay in ARIA live region announcement

[Francisco Javier Dorado Martínez <javier tiflolinux org>]

Hi all

Frequently I need to work with Google documents. Although Orca's has
good support for ARIA applications, I found there is too much time
between announcements for live region updates. This is no problem for
many applications, but when you
have to work editing or reading a document it's a bit unresponsive.
I have tried to change politeness level but without luck, Orca takes up
to 2 seconds for announcing changes.

Steps to reproduce:
1. Login to Google Drive and create a new document, or spreadsheet
2. Enable sticky focus mode by pressing a twice.
3. Type some text and use arrows to read it

Google's uses a live region to present messages when you move the caret
or perform any operation.
Orca takes up to 2 seconds to speak changes for this live region.

Can we modify this behaviour? is there any setting I can change to
adjust tthe delay between announcements?

Any help would be very appreciated.

Many Thanks,
Regards,
Javier
