I wipe and reinstall OS X about once ever few months—probably more than necessary if I'm honest with myself, but then, it has become my go-to way to fix problems, and I've become very fast at getting everything set up again.
There is however one thing I have to do after every reinstall that takes quite some time on my slow internet connection: re-downloading the "enhanced quality" version of the "Samantha" system voice (my personal favorite).
Is there any way I could back up this enhanced voice so that I won't have to re-download it every time I install OS X? Ideally, I'd like a simple .pkg file I can just double click to install. Such a .pkg file for "Enhanced Speech Recognition" can be downloaded here, but I can't find anything similar for system voices.
