This kind of user modification of the UI sounds like what people
currently do with Greasemonkey scripts and other browser extensions. I
think that the same mechanisms should work fine for speech UIs as
well, e.g. by using user-scripts to modify the DOM. I think that
allowing this is a browser feature, and that it falls outside the
scope of most web standards. For example, I don't think that any HTML
specs require allowing user modifications.
