tranny voice

Why is it that:
- MtF trannies with high voices still sound like men
- normal women with low voices still sound like women

I listen to a lot of porn audios and it's extremely, I mean extremely obvious when the girl is a tranny.

Also, I've heard a lot of deep female voices in media that sounded distinctly cisfemale to me. The voice of Winter Wyvern from Dota2 is a great example.

What actually makes a voice sound male/female?
