Hey guys,

First off, let it be said from the horses mouth that I got speech going in
my audio plugin with a botch. I did NOT port the speech system over to

There are a number of technical issues which need to be raised before the
speech system can be opened to the plugins in a way which will be of LONG
TERM help. There's no point in getting it wrong three times - it will
come, give it time :)

For one, I patched-together everything I needed out of samples that were
already available, adding more is currently out of the question. I would
propose that on a more generic scale, each plugin have it's own speech
file, as well as access to the core speech-lib ...which in itself causes
certain memory issues ...and so the wheel turns again.

My intention is to wait until Rockbox has full plugin speech support (and I
feel it is likely to happen) and then change Audio-3587 to suit that ...not
the other way around.

As for the next release of Audio-3587, very sorry about the delay - it has
been hell here.

I have had to simultaneously work on the new graphics lib, A rapidly
changing UISim, repair the broken devkit (rebuild form scratch), fix bugs
in audio-3587, not to mention "have a life" in the gaps in-between ;)

I anticipate the beta-2 release of Audio-3587 "any day now" ...but then
I've been thinking that for about a week now - LOL
