Ok, the new version of ttsd, 1.0a3 is available for download.

It includes the audio overlay patch. Tony, with an unpatched kernel, does it work the same as before or does it not run?

The other big change (for me atleast) is that pcmplay is now integrated into flite. So this version is slightly smaller. I don't yet have looping logic in flite, so it still needs the shell script to run it again after it says something. When I get that included, then the memory footprint won't include bash (yay).

I was expecting to have to play with priorities and worried about giving flite a low priority and pcmplay a higher one (making integration difficult), but that wasn't even an issue... just running at default priority works fine.

In this version, I broke the ability to have flite write to a file (it will only write to /dev/audio). I'll put that back in the next version... it was just easier to force it for now.
