A downloadable chatterbot for Windows
Talk to your newly acquired waifu using the powers of voice recognition and hear her soothing mechanical voice talk back! Too shy to talk? Press space to hear the height of artificial humor.
Includes the source, in case you're into that kind of stuff.
Requires XNA 4.0 to run. If you don't have that installed, don't panic, just run xnafx40_redist.msi from the game folder. To run the game, run talk2waifu.exe from the game folder. No installation necessary (aside from xna, obviously)
