Ok i can understand that she think ur a man BUT HOW CAN’T U TELL IF SHES A WOMAN OR NOT DUDE
If you meant the voices, then I apologise, I misunderstood you.
But still, altering your voice can really change it. And if you do it so much, you will be able to convice others because it is so much different than your original voice. Tone means more, too.
If you whach anime, see one episode of 'Detectice Conan', the mc's voice is a woman's (If I know right), and voices a male kid, and her 'serious' voice resembles of an adult man.
Or there is Aoi Shouta, who is a man but can easily play as a woman despite being a man.
Voice should not be the one thing you pick out...
(I'm not a prick and likes just feels like these aren't the things we should point out to why would they be this or that particular gender)
They fucking look likes Mii lmaooo
