> MiyabiHe speaks slow and clear, and uses simple vocabulary. Sometimes he mixed up his words though.
> IzuruSpeaks clearly but sometimes he speaks quite fast and strings his words in a long sentences.
> AruranSpeaks very clearly but his vocabulary is sometimes hard to understand especially when he's explaining technical stuff. Also sometimes he tells a joke with a straight face, so you have to grasp that in context.
> RikkaSpeaks soft and sometimes mumbles his words, so might be harder to catch
> AstelSpeaks clearly but I feel like you have to understand a lot of context to get his joke or his nuance when he's addressing stuff.
> TemmaClear pronunciation but sometimes he speaks quite fast. He also sometimes uses difficult vocabs or anecdote to make his point.
> RoberuAlso speaks very clearly and quite quickly, but he repeats his sentences a lot. Once you get over his accent, it might be quite easy to understand him.
> ShienI think he speaks the clearest out of all OG9 and he also repeats his sentences a lot. But he often uses modern slang that switches around the order of words, so that part might be hard to understand
> OgaSpeaks very clearly and uses simple vocabulary, easy to understand and he also uses the speech translator so it might be the easiest to understand him.
