I'm still working on this off and on, as well as the add-on accent system.
I got bored, and
made a clip of four of the accents being used side by side for a comparison. All four NPCs have the exact same string fed to them, modified by the accent routine before the SpeakString call is made.
Likely I should have had on some background music or such, likely I could have found something appropriate to go with it, but didn't feel like recording it again.
As the description in the clip says, the accents used in it are dwarf-Faerun, High Mordentish (Ravenloft), Reptilian, and Dwarf - Ravenloft.
I'll update that part of the package again once I get a few more made. I only have six finished at the moment.
