I was just doing my lesson for the day and I noticed that the Chinese language speaker had also incorporated a female voice. I think this is great, because people speak things differently. My problem is that the characters were mixed up between voices. You would get 3 in the male voice, 2 in the female, then 1 male again. I would prefer that either each lesson gets the same voice for the whole thing, or that the voices could be toggled between male and female.
