So yknow how sounds like せい、へい、おう are pronounced with a long vowel (sē, hē, ō)
Why is it that the audio in both WaniKani and Memrise pronounce it like sei, hei, ou in some words? For example, 兵士 is pronounced heishi instead of hēshi. 正解 is pronounced seikai instead of sēkai. 上演 is pronounced jouen instead of jōen.
Is the audio correct? I’ve always pronounced these words with a long vowel and now I’m really confused. Thank you
