日本語アクセントの歴史が変わった！？最新科学が暴く「東京式」と「京阪式」の意外なルーツ【言語学/ベイズ統計】【ゆっくり解説】

This time, we'll explore the history of Japanese accents. "Rain" (ame) and "ame" (candy), "bridge" (hashi) and "chopsticks" (hashi). Why do accents differ by region? For many years, the prevailing theory in the world of linguistics (according to Haruhiko Kindaichi) was that "Kyoto accent evolved into Tokyo accent." However, recent research using a scientific method called "Bayesian phylogenetic analysis" has shown that this theory may be overturned! Ancient documents from the Heian period and living fossils found on Ibukijima, a small island in Kagawa Prefecture... We'll slowly explain the mystery of language that spans thousands of years.
