The new voice feature of Google Mobile is pretty cool, but so far it seems like it's recognizing my queries only about 10 percent of the time. I found that if I make the query very simple -- like one word -- it seems to work better. Yet I got a result when I said "Weather in Fairfield, Iowa." When I saw the blog item by Matt Cutts on tips for using Google Mobile, I got excited, thinking he'd have tips for improving accuracy. But mostly he deals with other things. Still, it's a great post and explains some neat features that aren't immediately obvious when you start fooling around with it. These include pressing the magnifying glass to repeat your search in Maps, Images, News, Shopping, or Wikipedia. Also, if you press on the green query in the search box, it will pop up a list of other interpretations of what you said.
