As I said last week, I'd like to try it, but I'm not convinced. The
clicking might be annoying to some, and the wait/loading splash really
signifies a longer wait than usual, which I think is a different
information.

Oh. OK I've updated it and tried it out. I'll upload my version and
comments shortly. It's not working too reliably for me though :-). I like
some aspects of it, but I don't feel it really replaces the loading splash
information.

Now do you mean remove the voicing of the loading splash, or remove the
splash itself?

I agree that the non-visual interface should try to convey the same
information as the on-screen UI. Using the same strings is often the best
approach. But I do feel that some creativity is called for in some cases
to provide a smoother non-visual UI.

Now if you're saying that the entire loading splash is annoying to you,
then that's another story. But your initial post said you were annoyed
specifically by its voicing. Seems to me speaking "loading" IS an exact
match to the displayed UI, and that's what's annoying you. But that splash
is indeed somewhat special, among other reasons because it's a zero
duration splash.

P#8067 adds an exception case in the voice processing, but it at least
conveys similar info to the displayed UI, and the exception makes it
smoother. Removing the voicing of the splash while keeping the splash on
screen would be a much bigger deviation IMO.

<slight digression>
Speaking things outloud allows to convey a great variety of info and is
easily interpreted by new users, but it's not necessarily the only means
available in a non-visual UI. Sound effects are a bit like icons on a
screen: they're require less attention to interpret, although they work
only in cases where the interpretation is obvious. And of course sound is
a fairly linear medium compared to a screen, so things can't always match
exactly.

If you mean to take out the wait splash completely and replace it with the
keyclick, you should probably ask sighted users for their opinion :-).

IMO hearing the click on each key press builds an expectation of
instantaneous response: you're so used to it that you stil feel things are
stuck when one particular key press suddenly seems to have no effect and
has you waiting for a few seconds. As I said before, I find the loading
splash most appropriate on disk spin ups. Conceivably it might be taken
out altogether on flash players. Oh and also, it could be argued that the
playback beep and the loading splash are two inconsistent ways of
conveying the same info.

Definitely. But OTOH a disk spinup takes long enough that there is plenty
of time to play a more indicative sound.

Now I've tried and updated your patch, and will go post comments on the
tracker. Will you at least try mine out please?
