Unfortunately, no. Third party companies do make specific microphones for Wii (like Logitech), however they will not work as well as first party microphones. Microphones made for PC won't work. The Wii speak accessory is still available at the Nintendo Online Store for $30: http://store.nintendo.com/webapp/wcs/stores/servlet/ProductDisplay?productId=146210¤cy=USD&catalogId=10001&tranId=0&lastAction=setCurr&storeId=10001&languageId=-1&categoryId=62707&ddkey=http:SetCurrencyPreference
However, you can find it much cheaper on Amazon ($12)
