This will be nice for navigating my playlists while driving; currently I have
them moved into individual subfolders to obtain the voicing. I can't see ever
using it for music files, but some of our Blind friends may want that option,
and perhaps the audio book listeners who listen while driving.

I'll update the script ASAP. It may be best to make separate versions so that
nobody "accidentally" makes clips for all their songs. I can imagine that taking
a *looooong* time.

As far as the script is concerned, have you found a certain set of parameters
for the SAPI voices and LAME that generates better sounding clips than others? I
know that some of the versions that were tried (in order to keep things
compatible with the digital output, for instance) made clips that sounded very
"scratchy", as if there were a lot of high frequency noise.

Sounds fine. I never used "on enter" personally.

Would it be easier to implement a per-directory setting for this, i.e., only
look for file voice clips in directories that are flagged to permit this? Or
would checking for the presence of such a flag generate almost as much activity?
I'd only use it on a very limited basis, but I suppose I could just toggle it on
and off with config files, as needed.

Ahh - I'd probably want to voice files in the folder where I store configs, too.
