Just admitted on main to being a huge vocal synth lover and having a fixation on it, so here’s my “which vocal synth would sound similar to my ocs (and by vocal synth, I mean original characters from vocaloid and vocaloid-esque systems and not voice actors who got their art stolen by ai)”:
Xander - Kevin (SynthV). I’m trying to imagine more but he would sound super similar and that hurts lol. Possibly VY2/Yūma (Vocaloid) or An Xiao (SynthV) but I’m still unsure.
Mia - Kikyuune Aiko (UTAU), Ci flower (CeVIO), Kasane Teto (SynthV). UTAU Teto and Vflower are too crunchy for them, but they also work
Carol - Haruno Sora (Vocaloid/SynthV), IA (Vocaloid/CeVIO), Luka (Vocaloid). Calm and gentle, quite deep
Ricky - Fukase (Vocaloid), po-uta (Vocaloid), JUN (SynthV), SAROS (SynthV). Slightly ambiguous but quite masc
I’m only doing these four since they’re the clearest speakers in my head.
