I don't know about you, but I'm all for simplicity where voice control is concerned. I have been using a product for about 1 year that accomplishes all you wish to do without being tied to a computer. This product is the Mastervoice Series II. In one small unit this product combines voice control, telephone control (of x-10), timer routines, macros, if then routines for x-10 (2-way only) and so much more. It speaks and responds to voice control of up to four different users. These devices retailed for around $4000, but I have seen several on Ebay (where I got mine) for anywhere from $250 to $500. There is an optional IR controller as well which I am using. Take a look at http://www.mastervoice.com and click on series II. You won't be disappointed.
