hi i was just thinking of a new idea and i thought of a bedroom light controller then i thought of a dimmer but then i thought it would be a pain to build or have to stand up to get a remote or press a button then i thought voice controled because i think lots lol i was just wondering if this could be possible using something like a picaxe and a small ciruit im not sure how we could wire it into the mains 240v so any help will be great thanks.
Get your voice recognition working first, then worry about the mains interface - to be honest, it sounds a silly idea! - even commercial voice recognition doesn't impress me greatly!
sorry should have said that a bit better on some dimming switches you press a button or turn a little dial to change the lights brightness. hmm to get the voice recognition would you simply use something like a microphone to a input on the picaxe thanks

I suggest you try looking into the difficulties of voice recognition?, which you aren't going to do with a tiny amount of program space and a very slow BASIC interpreter.
Get an old computer with a 733 Pentium III in it, and put M$ windows on it, along with a good flavor of the .net suit (i would suggest VB.NET, or C++, or C.), then download the MS Speech SDK. Simple as pie. Just a few lines of code to get a simple voice recognition program, and then another couple of lines to send data out the parallel port.

How practical would it be to do it on a PIC? And how would this be expensive? Yeah, sure, the computer would be running for a long time, but the code would be free, and i am sure you could get a suitable computer for free at a yard sale.
As for reliability, it isn't very good, but, like you yourself said,

Reliability does go up after the "training" sessions are run. I doubt one could match the quality (or lack there of) of the Speech SDK on a simple PICAXE.
Another advantage of using Linux would be that as you don't need graphics you wouldn't bother with the X window system or a destop so you could get away with less RAM.
Also some BIOSes actually underclock the CPU when it isn't being used to save power. You also might be able to configure it to but the system into sleep mode and only wakes up when the microphone recieves sound.
