One of the coolest features of Animal Crossing: City Folk for Wii (the newest game in the Animal Crossing series) is the fact that the game supports Nintendo’s new microphone accessory, the Wii Speak, which allows for voice chat when playing City Folk online with friends.
The microphone can either be bought bundled with the game (at an American msrp of $70 or just the game for $50) or separately (just the microphone) for $30. And eventually other games should support voice chat while playing online, but right now it’s just City Folk.
When you buy the microphone, packed inside the box is a 16-digit “Wii Download Ticket” code that allows you to download the “Wii Speak Channel” to your Wii Channels menu. The channel allows you to simply chat with an unlimited amount of friends in one of four available chat rooms. Each user is represented by their Mii who will lip-synch what they are saying. In addition the Wii Speak Channel allows you to leave friends audio messages as well as attach audio clips to stored photos. You can also share photo slid shows and comment on them with the Wii Speak Channel.
Give a look at how the channel works and how to download it in this video.
