To be fair, Miki and Miku are pretty similarly spelled? So it’s a possibility that it was a small mistake because of the names being so similar, but you’re correct, miku sounded like a dying cat in 2011 for most songs, only the best of the best could make her not sound like that
Bro miki and miku sound sooo similar, not to mention their names are one letter off, I made this mistake at first too it was an accident on the creator 😭💖
