Pronunciation differences in 四つ仮名 (yotsugana)


Many of you probably know about the so called 四｛よ｝つ仮名｛がな｝, じ ぢ ず づ, and that
in standard Japanese only two different pronunciations for them exist, that is
じ=ぢ=/=ず=づ. However, they used to represent four distinct sounds, something
that has been preserved in some regions, especially on Kyushu. See this map:
<https://en.wikipedia.org/wiki/Yotsugana>

Now to my question, my own Japanese is from a 二つ仮名 region so I never had the
opportunity of actually learning the other sounds. Therefore I was wondering
if any of you know of any recordings, preferably videos, that clearly
highlights the different pronunciations.




A dialect that has difference between ず and づ. That between じ and ぢ seems
lost, though.
