Vista has speech recognition, why doesn't Julio?

Julio has decided snow and slush is good to eat. The problems are that 1: he is NOT supposed to be eating anything other than stuff I give him, and 2: I don't want him to get sick from the salt and chemicals that snow gets treated with to melt ice on the sidewalks. We're going to walk to Brewberry's today, which will be good, because I notice that getting the sweety off the campus helps with his focus. I can't blame him, it's hard to focus on similar routines.
