Cleaning again, getting to the last few boxes under the bed, stuffed there after the move. And it occurs to me that I want to be able have the following conversation with my house:

O House?
Yes, my son?
Where does the flashlight go?
The flashlight goes in Junk Drawer Three.
What is Junk Drawer Three?
Junk Drawer Three is in the kitchen, under the cupboard, second drawer from the left.
Thanks.
Aye aye.
O House?
Morning, sir.
Where does the whiteboard eraser go?
I don't know.
The whiteboard eraser goes into the top desk drawer.
OK, the whiteboard eraser goes into the top desk drawer.
Thanks.
Live to serve.

Surely the technology exists to make this happen. I want to know what sorts of speech-recognition software exists for Mac OS X (I used to know... hee hee, I get to look up stuff in MOSXiaN again; I love doing that), and how one might build an interface between that and Perl. Then it's just a matter of clever mic-and-speaker arrangement. Well, and buying a dedicated computer, but.
