Hey man, that's about as slick as it gets. I'm an Asterisk fan too. I run it
on my file server which is connected to mythtv via 100BaseTX and NFS.
I used to use Asterisk for voicemail and VoIP a lot, but since I bought a
cell phone I really only use it for faxing, and callerid display in MythTV.

Honestly, I didn't know voice recognition existed in Open Source yet.
Now all we need is to combine it with OpenVXI and we'll have a full
featured OSS VoiceXML solution:

One suggestion: Hack up lirc to take voice input and map it to key presses.
That way you'll already have lots of application support (mythtv, xine, etc)
and an established API.

Good luck!
