Yesterday I was playing Half-Life 2 and realized one of the female NPCs following me around sounded like a snarky combination of Serana and an Imperial woman (i.e. Arcadia, Adrianne, Rikke, etc.)

So, I dug around in Half-Life's sound files and, lo and behold, additional voiceset.

Installation:
Copy the archive (7z) contents into the data folder, allow overwriting.
This mod will overwrite "set2" of Nanahane's original mod, which in case you couldn't tell is required for this mod to work. You can rename the "set" folder to make it replace any you want, but default will be 2.

Uninstallation:
Delete the folder "set2" from "C:\Program Files (x86)\The Elder Scrolls V Skyrim\Data\Sound\FX\nhva" and copy the "set2" folder from Nanahane's mod back in its place.

Sounds are all property of Valve Corporation, with the exception of blank .wav files to add silence and overwrite Nanahane's origional files (wouldn't wanna suddenly speak Japanese)
