Need an opinion on home automation and speech recognition

["Nath" <ndg26@xxxxxxx>]

Hi,

I'd like to automate certain simple tasks at home (for example turning
on lights) using voice commands.

I already have a few X10 devices communicating with a linux box.

I'd be very please to hear about your opinion on the subject. Success
stories... Hardware requirements? Is it hard to set up? What to buy?
Good books on the subject?

Thanks a lot,
Nathalie.
