The Milwaukee Journal Sentinel did what's probably an obligatory SuperBowl piece: They interviewed people in Dallas, asking them to pronounce Wisconsin placenames, pretty much all ones of Alongonquian origin, I think. Here's the link.
If you need help with Wisconsin names of any sort, you can go to Mispronouncer. It's especially useful for people, since the site tends to have public figures saying their own names. So, you'll hear for example that State Rep. (and bane of UW's existence) Steve Nass uses the German-like vowel [a], not the [æ] people often use for his name.
