@EduardPontier idk if i tagged it right but if you go on textfugu.com you can go through most of season 1 for free which inclues hiragana and the prounounciations of all the kana.
however, a i e u o are the 5 basic vowels without consonents.
a = aah
i = eee (like the ey in key)
u = ooo (like the oo moo)
e = eh (like the eh in read)
o = oh (like the second o in oreo)
and then all the other kana (excluding n which is pronounced nnn) are a consonent and one of the five vowels (a i u e o) so they're easy to sound out from there. except ra ri ru re and ro which are pronounced with a hard r, but it's better to learn that from videos where you can actually hear how it's said
