im so painfully curious now how u decided like...how to tl the characters speech patterns now omg
KHTROUJFGKL its kinda hard for me to explain my process but its really just a combination of what nuance i pick up from the japanese + just kinda the...vibes of what i get from the characters KUDTHJGF i could probably talk all day about it tbh but it really depends on the character...!
if you want an example i think my process of how i tl akuta could be an interesting one for me to explain! in the japanese he of course speaks very casually and inserts a lot of exaggerated/excited wording and onomatopoeias into his speech + he very occasionally talks almost like ... like hes playing a role in a movie lol? (see day2 mainsto a22, when he talks to nanaki like hes a samurai: ใ้กใใใใใงใใใ๏ผ)
so to tl his casual and energetic speech into english i write him with simple words, shortened words (e.g. "wanna" instead of "want to," etc), run-on sentences (e.g. he says stuff like "[word] and [word] and [word] and [word]" a lot, esp when he gets excited), a healthy handful of intensifiers that i feel suit his character (i really like using "friggin'" and "as heck/as balls" for him KDJTHGF), and what i really like to do is tack on a "bro/dude/my friend" onto his sentences for that extra little teenage boy-ism
the other half of how i tl akuta is where the vibes come in... akuta reads as an excitable little kid to me so thats why, for example, i consciously make the decision to never make him say any curse words and instead opt to make him say "kiddie" replacements for curse words, like fudge or frick instead of fuck, holy cow instead of holy shit, etc, just because i think it fits his lighthearted and whimsical vibe more. i usually dont make him say a lot of modern-day slang words for a similar reason but theres definitely more room for flexibility in that realm kUDTJHGF
so... yeah! def varies by the character, i mostly just try and catch the details from the jp and transfer those into english as naturally as possible and then add some flavor based on the character's personality and image. if theres anyone in particular youre curious about anon just lmk!
