Hi Scott,
Cc'ing this to the Rockbox list for others - hope you don't mind.

Currently, the quick screen cannot be spoken without changes to the
Rockbox code. I can see this myself looking at the code, but it is a
little difficult to explain. Suffice it to say that menus presented with
the standard Rockbox menu code are automatically voiced, but the quick
screen is not a standard menu and therefore needs additional code for
the items to be spoken, which is not a trivial task. I don't quite
follow why the quick screen is non-standard or how it is different to
most menus, but i can definitely see that it isn't by looking at the
code. I'd have to spend a little more time examining it to work out why;
my understanding of Rockbox code is still very sketchy at best. Can
anyone else shed some light on this? I don't really even understand how
the quick screen works.

The most up to date english.lang formatted for makevoices, including my
own changes (currently only the inclusion of the edit preset and remove
preset voice entries), can be found here:

Only with changes to the code. Perhaps make a feature request on the
tracker?

When you enter the sound settings menu while audio is playing, Rockbox
enters low latency mode so that sound setting changes will occur with
the lowest latency possible; i.e. almost immediately. It is not possible
for the voice UI to work in this low latency mode. As I understand it,
there is not enough audio with which to mix voice clips, as the amount
of audio in the output buffer gets shortened to lower the latency. I
have suggested that perhaps low latency mode could be disabled by a
setting and/or while a voice file is loaded, but this would mean rather
large latency if crossfade is enabled depending on crossfade settings. I
still think this would be better for me, particularly as I don't use
crossfade, but even if this does get implemented, it won't be until
after 3.0.
