OK, I can try that. ;-)

This is strange. Do you have inconsistant sources, or is anybody else
getting this, too?

Yes. I used TTS to make separate clips from the number "atoms" (I had to),
so the program is phasing out the voice at the end. Some more agressive
ttrimming (requires manual work) could improve this.

This again could be reworked in the voice file, to have it not really using
full range. Another way could be to have a configurable "delta volume" for
the voice, but I'm not too fond of another option.

I'm not sure I understand how this would improve. I don't want to load the
voice file without necessity, and not generally on boot. So I load it when
it's needed and not in buffer. Can I be more graceful or prophetic?

There's one change I want to do against the existing implementation:
The check if the voice file is present will be moved to talk_init(). At the
init time, the disk is spinning anyway. Currently this is done when the first
clip is needed, i.e. when entering the menu for the first time. Users
without the voice file get an unnecessary spinup here. Later it remembers there's
no file and doesn't try again.

> - I want a global option to enable/disable voice.

Certainly. I was planning to do that together with the talkbox patch, which
also needs 2 options. The question would be where to put it. Talkbox options
used to be in the file view menu (makes sense), versus the talking menu is
something else. On the other hand it would make sense to have all the talk
options in one place. Any opinions?
