Re: Belgium language
Here is a Wisconsin update.
Professor Kelly D. Biers (University of North Carolina) plans to create a Wisconsin Walloon primer that will be easily accessible to the Wisconsin Belgian community. The primer will include basic information about the language and essential words and phrases which will allow current and future community members to understand, practice and thereby preserve a record of their language. The project involves the development of an orthography and content for the primer, involving native speakers in the creation and editing of materials, and dissemination online and in print. Much of this process is already underway and has received enthusiastic support from community members and organizations.
He started is research of the language in 2015, and he just recently published a 10 page paper by titled: "Quantity-to-Quality Contrast Shift and Phonemic Merger in Wisconsin Walloon High Front Vowels "
