Thank you.

I'm Linux only, I have to get orca working but I can't test with the 
screen readers that most people use until I can afford to build a 
windows system again.

I was just going off of what the Mozilla page says, which is that 
changes should be read to the user as it updates but it will only update 
when the audio itself is playing.

Sometimes it is used as a live region (with aria-live), but that is a different matter. You should be OK with the role progressbar (or timer, which has an implicit aria-live="off").
