Ah it's a setting for Text To Speech functionality. Guess they replaced there being just a male and a female voice with there being a list of different voices each identified by a name.
You're probably right, but my first thought was Luffy from One Piece, voiced by Mayumi Tanaka in Japanese and Colleen Clinkenbeard in English, both women.
(Also, I can't get over what a good name Clinkenbeard is for a VA who voices a pirate)
