Hi everyone, This is my first post (at last!)
One thing I don’t really understand is the pronunciation of ～あい sounds (ない、ばい、だい…), are they pronounced (roughly) /aj/, /aɪ/, /a.ɪ/ or something else? (This is the IPA for those who don’t know)
Edit: Forgot to add this, most of the times it sounds like /aj/, as in ない but sometimes it sounds to me like /aɪ/; maybe it’s only me…
It’s worth noting that in very informal (usually masculine) speech, words ending in ai-sounds frequently are pronounced ee (as in ehhhh). Not something you should learn to do in more polite settings, though. Example: 本当？ 行きたくねえよ！ (Really?! I don’t wanna go!)
On another note, is じ pronounced as /ʒɪ/ (as in vision) or /dʒɪ/? (as in gerund) Because I’m pretty sure I’ve heard both in WK. And is there any difference between じ and ぢ, in their pronunciation?
For all your pronunciation questions, I’d recommend checking out Dogen. He has a few free phonetics videos on youtube and the rest of them are available to buy on his Patreon. They’re really well made and really useful.
Also, in lesson #43 he says じ is pronounced as dʑ at the beginning of a word, and can often become ʑ after a vowel. (He also has more information on this in the video.) I believe he said じ and ぢ once had differences in pronunciation but in modern Japanese do not.
In another lesson, he also covers how to pronounce あい if you want to check that out!
