Not sure for other dialects. But for Kansai-ben this site has been quite helpful to me. It has structured learning materials, recordings and other useful resources.kuroi_shinigami wrote:I'm still having difficulty understanding dialect. Most used dialect I encounter so far is Osaka-ben(actually Kansai-ben) and it's quite difficult for me to understand the meaning of kansai-ben if they don't use kanji. I also sometimes encounter another dialect that use べ in the dialogue ending a lot, I think it's from Hiroshima or somewhere north. I wonder where can we self-learn these kind of dialect?
