So, I am having a hard time with a ton of leeches, and almost half of them are さざせぜそぞ related. I simply can not hear if it should be with a S or Z sound, and that makes me highly unsure of which one I should use.
Do anyone have any tips for studying when to use what kana? Or just how to better hear what sound is being said. I am unsure when the z sound is not simply a rendaku that happens all the time with the correct kanji/sound combination.
