Welcome to the myhosting.com Forums.
I know the technology is still pretty new, but does anyone incorporate voice activation into their websites so users can navigate it just by speaking? I'm not even sure if this is possible yet, but I'd love to see examples when it is b/c I think it would be incredible.
I'm not aware of any technology that incorporates speech recognition into websites. This is a function of the operating system (not the web site):
What you can do, however, is make sure that you don't use images to represent text. Speech recognition software ignores all images, even ones that contains pictures of text.
