Historically, most of Silesia was German speaking until 1945. Today, the vast majority of the region is Polish speaking with accompanying smaller regions speaking either Czech or German. There is a small German minority to be found in Upper Silesia. Upper Silesia is also home to a separate Slavic language/dialect, also called Silesian.
