I want to know the answer to the following question:
Where do dialects tend to be limited to in the Italian speaking regions?
All the background I'm provided with is that "The role played by dialects in each linguistic region varies dramatically: in the German-speaking regions, Swiss German dialects have become ever more prevalent since the second half of the 20th century, especially in the media, such as radio and television, and are used as an everyday language, while the Swiss variety of Standard German is almost always used instead of dialect for written communication (c.f. diglossic usage of a language).". Is that enough to answer the question?
Answer: no
